Big analysis of Tsukasa Yugi, part four.
So why is Tsukasa so difficult? The answer is obvious. He was simply overwhelmed by circumstances.
1) What happened with Amane.
Everything that happened to Tsukasa affected his psyche. Starting with Amane yelling at him, which Tsukasa interpreted as hatred. But was that really true? Amane hardly hated Tsukasa at that moment; he was simply too tired and snapped at someone close to him, not implying that Tsukasa was bad for being healthy. However, Tsukasa took it as a personal insult. He remembered this, and at his birthday party, he asked if Amane loved him. If he was so sure she didn't, why would he ask again? Wasn't it to make sure that since they were now equals, Amane had no reason to hate him? After all, when Tsukasa answered "of course," she smiled and replied, "Good!" As if that would make him feel any better. It hurt him, after all, that Amane could hate him. As if he could sink to the bottom of a well with peace of mind.
But in captivity, the problems with this approach became apparent. It seemed easier for Tsukasa to believe that Amane actually hated him, because that would make it easier to not miss home. If he wasn't welcome, he wouldn't want to return. It's as if Tsukasa convinces himself that Amane is angry with him. Because when he's alone in the burning house, he recalls that same scene of the question, the answer to which was "of course I love you." It's as if Tsukasa still wanted to believe it deep down, and now, after the news of Amane's betrayal, the image of that belief is crumbling before his eyes.
Amane doesn't love him after all. Yes, that's obvious. When Amane killed him, "his face was the face of a man who didn't hold back." Tsukasa is now certain that these are Amane's true feelings for him. And he's partly right to believe this, because although Amane loves his brother, he loves the image of the "real Tsukasa," and blames the one in front of him for everything that happened to their family.
Amane is still attached to the "fake Tsukasa," but as if projecting it, clinging to the remnants of his brother's image, constantly separating the two Tsukasas.
But Tsukasa continues to strive for his love, even though he's certain he won't receive it.
Tsukasa asks Amane how he feels at his birthday party, and his vision of the desired answer is shattered. Tsukasa lies to Sakura that Amane was happy to see him when he first appeared on the roof in chapter 17. Obviously, it's not quite that simple. He still calls Amane with his lips as he falls from the keepers' cage. He doesn't believe it, but he wants to. He tries every time to get his brother's attention, even though he's long since given up, simply because he still reaches out to Amane. Even if Amane doesn't respond. "You're weird," he says, "you hate me, but somehow you still miss me." Tsukasa refuses to accept that Amane's longing is connected to warm feelings for him; no, it's just Amane being weird. And Tsukasa doesn't understand him. Just as Amane doesn't understand his brother either, something he tells Nene and Kou, and Tsukasa himself, constantly asking why he acts the way he does.
The twins are so separated by circumstances that they literally exist in different timelines — young Tsukasa learns of events that haven't yet happened or have already happened, but in the distant future and later, he acts according to his knowledge, even though the other characters have no idea what's destined to happen. Unsurprisingly, Tsukasa is misunderstood by both his own brother and the rest of the cast.
Tsukasa also speaks directly of his incomprehension of his brother's actions. "I have no idea what you're thinking," he says to Nene and Hanako, frozen on the boundary of the First mystery. Tsukasa hasn't understood his brother since the moment he trampled his victim. After all, Amane assured him that if he were given health, he would be happy and would need nothing more. And so he gets it, and what happens? Amane rejects the path to happiness, choosing the strange behavior that leads to Tsukasa's murder. "Why did Amane do this?" is Tsukasa's main question, and it seems he still hasn't found an answer, since Amane does it to get rid of the counterfeit. We don't have precise data about 1969, so I'm not sure whether Tsukasa knew exactly why Amane was repairing the clock. Because if he had known, he wouldn't have been so confused by the emotional roller coaster of Amane never visiting him while locked in the boundary, yet suddenly becoming incredibly anxious and worried whenever they were together, somehow missing him. Tsukasa likely has little understanding of the gamut of guilt, attachment, and hatred for the counterfeit that the secretive Amane experiences.
Sumire, similarly disregarded in her imprisonment in the Sixth boundary, experienced similar confusion, convincing herself that since she was Hakubo's yorishiro, he must at least care a little bit about her. When Hakubo tells her he's ready to be with her, the despairing Sumire doesn't believe him and becomes angry, tired of hoping for it, afraid of being rejected and treated coldly again.
It's probably easier for Tsukasa now to believe only that Amane hates him, because, coupled with how much he still craves Amane's warmth, it would be too difficult for him to deal with a brother who continues to push him away. Tsukasa could probably accept Amane's love, but it's too late. He deliberately avoids his feelings if they seem too strong at any given moment. This is ironic, given how he expects directness and honesty from others. Tsukasa is actually very ambivalent. This isn't revealed right away, but with each new fact about him, it becomes more and more apparent. So what's going on?
2) How what happened to Amane affected Tsukasa.
The most traumatic moment in Tsukasa's life isn't the confinement, or even the domestic violence, but the way Amane cruelly devalued his entire sacrifice in one moment. He lied about loving him, lied about being happy, about how it was all worth it.
From that very moment, Tsukasa began to dislike certain things.
Because Amane lied to him, Tsukasa now hates lies. He constantly demands the truth from everyone, as discussed in the section on straightforwardness, the roots of which are partly linked to Tsukasa's trauma. Amane's lies were extremely painful because they robbed Tsukasa of the belief that he had truly helped him. Tsukasa no longer wants to be told anything when they actually think otherwise, only to somehow deceive him and perhaps painfully betray him again. Tsukasa demands the truth when he asks questions. Because he wants to know exactly what the other person wants. "Is this what you want? If so, I'll grant it," he asks ghost Mitsuba, Kou in the red house, hoping for an answer. And this is also connected to Amane, because it turns out he no longer desired health, but something else. Tsukasa always wants to clear everything up on the shore, so there won't be a set-up later; this is directly related to how he sacrificed himself in vain. Tsukasa is ready to see the most vile desires of others (like Amane's decision to kill him, or Kou's secret wish that Mitsuba ask him to commit suicide — a difficult scene, but Tsukasa only clarifies — so is this what you want? What do you want, Kou-kun, who tries to refuse everything the house offers, reveal your intentions already). After all, this allows him to better understand a person who doesn't pretend in front of him, but honestly states their position.
Clarity of expression becomes his ideology, and it's crucial in his wish-granting work, where one must truly be prepared to do what one asks for and be willing to face the consequences — Tsukasa demands this of Mitsuba. Fear is remembered best, he says, as does Amane. It's a law of evil spirits that the brothers learned from somewhere. Therefore, if Mitsuba wishes to be remembered, he must evoke strong emotions in people, and so it turns out that the more intense negative impressions do indeed linger quite strongly. When Nene refuses to destroy the clock keepers' yorishiro, Tsukasa agrees with her freedom of choice, but notes that he, too, has his own interests; it's his job to fulfill, so Nene will have to take responsibility for her decision and at least try to escape it.
Tsukasa wants others to take responsibility for their decisions, so they don't ultimately give up and devalue everything that happened while fulfilling their wishes. This is the same thing Amane did to him. He's angry that Amane gave in and "made life easier for himself," as he tells him in chapter 91.
After this conversation, he immediately asks Sakura if she regrets her decision, if she wants to give it all up, and smiles with a strange expression when Sakura replies negatively. He simply needs to process his devaluation trauma by seeking approval from others. Tsukasa craves recognition for his actions; after all, he didn't go through all this for nothing.
Something hurts inside him when he listens to Sakura, whom he deliberately asked if she regrets. When Kou is dissatisfied with Mitsuba's return, Tsukasa bluntly asks if perhaps he shouldn't have done it back then. His face clearly looks disappointed.
Because he's still upset by the fact that he spent his time and effort bringing Mitsuba back, something Kou also wanted, but now he's attacking Tsukasa because he doesn't like the methods he used. Tsukasa acted with such confidence while doing his job, yet he still asked this question, dissatisfied with Kou's attitude. Tsukasa isn't just acting like that, even if he says such things within the Third Mystery.
3) Connection with the hole demon.
"Just because," Tsukasa says, but I have a hard time believing that. The broadcasting club would benefit from gaining the power of the Third Mystery to facilitate their plans. After all, mirrors can show anything useful. Moreover, with this action, Tsukasa continues to fulfill Mitsuba's wish to not disappear. Sousuke's first ghost was exorcised by Hanako and failed. Tsukasa still has a fragment of his soul in his hands; why not finish what he started? Mitsuba gains a presence on the near shore, as he desired, and can now continue to search for his path. In exchange, Tsukasa receives a pawn for the radio club, with which he closely cooperates. (Of course, this is not touched upon in canon, so this is just my theory, as Mitsuba's mystery lore has been largely ignored for the sake of his personal drama, but that's his problem). The thing is, Tsukasa can be chaotic, but when it comes to work, he's always relentless and efficient.
Which is most likely related to the demon's rules of operation. This entity has its own structured processes. It requires a specific formulation, an equivalent payment, and it will fulfill the request precisely, regardless of the methods used to achieve it. These are typical rules of mythical creatures and the rituals associated with them, which is why the demon's wish-granting is so brutal. And here one could say that Tsukasa behaves this way in his work because of the demon's dictates, and I agree that he has to work by its rules. Tsukasa and the demon are inextricably linked from the moment he sacrificed himself to it. The demon takes over his body just like it does with other kannagi, eating him from the inside and driving him mad — though there's a curious twist.
Men can be more resistant to the demon's pernicious effects. We see this in the cave, where all the kannagi have long since lost their minds. Katakuri, though sacrificed later than them, is still quite sane after having been there for quite some time (his death clearly occurred no later than the early to mid-20th century, given the village's isolation).
Tsukasa himself is similarly sane, though he, too, has been imprisoned not for a year or two, but for nearly fifty. He was even still warm. Perhaps this has to do with the peculiarities of human spiritual power, how Minamoto women stand out to her compared to Minamoto men (Teru and Kou's grandmother was very strong, Tiara already surpasses Teru in strength and was the long-awaited daughter of the headman), how the women of the Akane clan also possess certain special qualities that allow them to influence evil spirits and be attractive to them (Teru mentions this in the new timeline), and something similar could very well apply to men and the demon. But just because the Tsukasa of the old timeline didn't become a full shell for the demon, as happened in the new one, doesn't mean he's completely free of it — as we see at the beginning of the fire, the demon has long since settled in his body.
Tsukasa simply resigns himself to this, which is reflected in the way he tells the demon, "Let's go back together." I believe it was only because of Tsukasa's decision that the demon allowed him to nullify its sacrifice. I don't think it would have let him go, leaving Amane healthy. In the new world, we see that the being won't let him break the sacrifice's promise, it curses Amane, "will not forgive" him for breaking the contract.
Tsukasa agrees to let the demon stay with him, sharing his body, thus creating a so-called symbiosis. I believe the reason Tsukasa decided this is because he considers the demon a kind of friend. Judge for yourself, it's the only thing that's been with him constantly throughout his isolation, and later he says, "I think humans and supernaturals should live together," which could very well be a reference to his bonding with the demon.
So, they're connected, and Tsukasa is bound hand and foot by it. Despite all the advantages in terms of immense power that the demon grants him, he, in turn, is obligated to help it "work" with people, identifying their desires, making deals, and fulfilling them. "After I'm summoned, I have no choice but to grant the wish," Tsukasa tells Shijima.
Well, that's how the school mystery works, and the same thing happens with Hanako himself. It's just that Tsukasa has been doing this essentially since childhood, when, in 1960, an entity emerged and actively exploited him, granting wishes left and right (the vicar of the Kunishige Temple is a prime example). And since the demonic rules include the principle "it doesn't matter how, or how many victims it involves," Tsukasa acts accordingly.
Efficiency trumps morality or other people's opinions of how it looks. Tsukasa may look like a maniac to some when he deforms Sousuke into a ghost with a broken neck, but he doesn't do it for any personal amusement — he wants Sousuke to be remembered, which is why he creates such a vivid image of him. Perhaps forcing Mitsuba to eat the Third's heart by force also seems questionable, but Mitsuba is weak and can't last long (which is what ultimately happens; the aquarium arc confirms that Mitsuba needs to replenish his strength, otherwise he will simply collapse back to his original state), so he needs to gain strength. Mitsuba resists (because, again, a piece of meat doesn't seem visually appealing to him), and since this is the case, Tsukasa has no choice but to force him for his own good. If Kou or Nene intervene, dragging him away from Mitsuba, he can slam their heads against the wall. This can be a toxic trait, of course. Violence for the sake of benefit, a questionable ideology, and Hanako's actions like depriving Nene of her freedom or killing her friend Aoi are considered toxic. Tsukasa is not gentle in his actions, but he believes he is doing the right thing.
Because he's well-versed in this ideology: "The methods aren't important, the results are." Tsukasa does this more subtly, but it's still the same when he uses blackmail against Amane and Nene to push them both into actions that will benefit the radio club's plan. In chapter 91, he literally blackmails Amane, first by pitying Nene, whom he can't help, then by pushing him to find a solution (it was literally a bluff on Amane; Tsukasa said, "I'm sure you knew," but when Amane agrees, Tsukasa is surprised: "So you did know"). Tsukasa plays on Amane's desire to save Nene. You want to help her, right? Then you'll have to do it (destroy all the yorishiro, which is also the radio club's goal and necessary for Sakura's wish to be fulfilled).
When the Hananene are frozen in the Clockkeeper's boundary, Tsukasa resorts to blackmail again, telling him that time will only start again if the yorishiro is destroyed. "You want to move on and live, right? Then you'll have to do what I suggest." The same thing happens with Mitsuba, when Tsukasa asks him whether he'll agree to disappear forever or choose to remain a mystery.
A choice without a choice, simply what Mitsuba would choose in this situation — of course, he doesn't want to disappear. Tsukasa pushes him toward the decision he himself would like to see. Verbal blackmail is also a form of violence, and also for some benefit, in Tsukasa's opinion — it will help fulfill the wishes he's committed to, it will help Mitsuba become stronger, it will help Sakura and Amane (it's convenient, of course, that the requirements for their fulfillment somewhat overlap, but that's a matter of lore).
Tsukasa himself agrees with the principles of the demon, which it demands strict adherence to (yes, he must see things through to the end. Tsukasa can't stop; the process has begun, as we see in the new timeline; the demon won't let him change his mind halfway through), but because Tsukasa himself was part of this process. The result justifies the means, and Tsukasa himself is the means. It doesn't matter that he will suffer in captivity; the important thing is that Amane will recover. It doesn't matter that he will disappear if the seal is removed; the important thing is that Sakura will fulfill her wish, which requires the destruction of all the yorishiro. "No matter how much pain you cause to achieve your goal, I will forgive you," Tsukasa repeats the words we previously heard from Amane. It is unknown which brother actually said them first, whether Tsukasa believes this or is simply repeating what his brother says; the important thing is that he keeps them to himself. It doesn't matter that others will suffer (for whom he asks Sakura about compassion), the main thing is achieving the result. He himself suffered greatly in the process of fulfilling his wish, and therefore cannot abandon the ideology of violence for the sake of benefit, thereby admitting that his suffering was in vain. So Tsukasa is unlikely to do something as significant as re-creating Mitsuba just for fun. There is likely a reason, the only question is how acceptable it is for society. Fulfilling wishes is a responsible process, the consequences of which must be paid for if necessary; this is part of Tsukasa's principles, and he is unlikely to decide on it without being prepared for these consequences, without a clear purpose for which he is doing everything. After all, he promised to help Mitsuba, but he was destroyed by Hanako, and although payment was received, the matter was not fully completed, one way or another.
Tsukasa, however, follows through and keeps his word. This is one of his relatively positive principles. Words must be kept, and he constantly demands this of others and strives to uphold the same himself. After all, he promised to heal Amane, make Mitsuba stronger, give him the chance to live with his friends as a normal person, and help fulfill Sakura's wish, and what do we see? Tsukasa only abandons his sacrifice for Amane when he learns it was in vain. And although he longed to return, he only held back for his own personal reasons. He also "remembered his promise" and didn't refuse to dive into the well, even though he might have become frightened and changed his mind. Mitsuba also ultimately becomes quite powerful, earning a place as one of the school's mysteries. If he hadn't decided to reject Shijima's world, he would have continued to successfully imitate the school life Tsukasa generously gave him. Tsukasa could also refuse to disappear just for Sakura's sake, or for that same Amane, who doesn't value him, but he still resigns himself to the fate of a yorishiro who will be destroyed for the sake of others. After all, he promised to fulfill their wishes.
However, Tsukasa doesn't always act in accordance with his demands on others. This is the most interesting aspect of his personality, in my opinion, because it's the most subtle of all that can be analyzed.
Tsukasa demands that true emotions be shown to him, yet he hides his own. We know he cried in the red house when Nene and Kou passed by. We know he was lonely, missed his family, and longed to return. Tears well up in Tsukasa's eyes when he exclaims that Amane is acting "selfishly."
However, he holds them all in, always greeting his interlocutors with a wide, seemingly deliberate smile. It's worth noting that almost all the characters hide their negative emotions behind smiles — remember Hanako, Kou, Teru, Mitsuba's mother, Mitsuba himself, Aoi — do images of their carefully crafted "cheerful" smiles ever come to mind? But you remember how they ultimately feel, right?
And if Tsukasa is a person with his own feelings, then the way Aidairo writes his characters doesn't really differ much from them. In an interview with Kikan S magazine, Aida notes the specifics of character designs, and her comment about Tsukasa is that "his pupils are intentionally drawn straight, unlike Amane's, to make it harder to read his emotions, making him more mysterious." So, Tsukasa is meant to be mysterious, but mysteries are meant to be solved.
After all, we know he cried in captivity. He's also hurt by Amane's behavior, offended by his decision to devalue the victim. Tsukasa remarks that while Amane protects Nene, he's decided to kill him, twice: in the donut chapter 15 and in chapter 91. The second time, he even emotionally calls him selfish. It's obvious Tsukasa is unhappy, but when it comes to the situation, in cases where he can control himself better than usual, he opts for the "smile like everything's fine" tactic. At the trial, he chuckles while talking to Amane about how strange he is, as if that's precisely what hasn't bothered him lately (literally the reason he left the red house, the interview card, the last concern—Amane, what he doesn't like about Amane—is that he's acting in his typical manner). Tsukasa even calls Amane strange with a smile on his face more than once. As he burned in the fire, he smiled, though he should have been crying — it was grief, after all — but Tsukasa was so shocked in the moment that he unconsciously resorted again to the "smile is okay" copium. In fact, ever since his self-sacrifice, he's adopted this strategy as a convenient one — the suppression of negative emotions. Recall how Tsukasa convinced himself he didn't miss Amane because Amane hated him, so he wouldn't want to return so much. Then his entire world was destroyed, and what choice did he have but to laugh while everything around him burned, like his former hopes? This is fine, as they say.
So, Tsukasa enjoys seeing others' honest emotions, but he hides his own, preventing anyone from seeing how upset he truly is. Perhaps he also doesn't consider certain events worth crying about, which is why he shuts Mitsuba up, as I mentioned earlier — Tsukasa himself never cried, even when he was burning in the ruined world, and he's accustomed to perceiving almost all events as unworthy of opening up, since he still hasn't done so even after all that's happened. Tsukasa is ambivalent about expressing emotions.Tsukasa also encourages freedom of choice in others and often seems to act of his own free will. But is this true in all cases?
5) Freedom and the Lack of It.
Tsukasa strives for freedom in itself due to the trauma of isolation, and for freedom of decision-making due to the trauma inherent in all kannagi. Sumire had a similar problem: she couldn't influence her own life; someone had decided for her that she would die, so her thirst for control spilled over into her attitude towards animals, about whom she says that they are dependent on her, and it is up to her to decide whether they live or die.
Also, since Amane acted as he wanted, devaluing Tsukasa's help, Tsukasa decides to act as he wants too — "I won't hold back anymore," he says. Finally, Tsukasa finds freedom, escaping the confines of the red house back into the past, having done so because he wanted to return. And so, it seems like Tsukasa is free now, right?
But Tsukasa actually embraces the path of accepting his circumstances. Just as Sumire essentially does, because she doesn't believe she can save herself (that the villagers will find her, order Hakubo to do it, and that he won't defy them, because she's not sure of him inside). So Sumire doesn't ask Hakubo for rescue, which he constantly wonders about. As if it's her fault — what Hakubo himself decided to act a certain way? But he does so too late. The same goes for Yugi's brothers. Amane doesn't change his mind about killing her brother, and Tsukasa becomes dependent on that decision. This murder becomes his obsession; Tsukasa returns with the desire to know why Amane did it, essentially accepting his fate. Tsukasa makes no attempt to escape or resist Amane; he knows where this is heading and simply waits for it to happen (that's how it appears today, until a refutation is published, for example, where Tsukasa would fight Amane). Is Tsukasa truly free in his choice to return to certain death? It's his choice, of course. But it's a choice made under the influence of circumstances, essentially a passion. The news that Amane betrayed him leaves a strong impression on Tsukasa. I've described how it affected him, and the ways in which that moment resonates to this day. Tsukasa essentially faces a choice without a choice. What's left for him to do? Stay in this confinement for some reason, convinced it's pointless, or at least return to his family? Tsukasa simply chooses what he wants, of course, what seems like a good idea to him. But it's not such a good idea; his family didn't welcome him warmly, and everything went awry. And it's not that little Tsukasa is wrong or at fault for getting involved; no, he's simply becoming a victim of these circumstances once again. He chooses to accept them, but because it's an easier path to copium than fighting them, addressing the elephant in the room, the futility of everything he's ever done — people with problems are afraid to acknowledge them, knowing they'll have to deal with them.
Tsukasa accepts that Amane will kill him, that he'll have to disappear as a yorishiro, that Amane pays more attention to Nene, that he's now bound by a contract with the demon, for whom he's now a errand boy, a prisoner of existence as a wish-fulfiller. Tsukasa accepts many hardships, such as the fact that Mirai has locked him in truly strong shackles and that he'll now have to lie in this cage. It's clear he's not very happy, and Nene tries to rouse him while Tsukasa once again goes through the process of coming to terms with the circumstances and perhaps even searching for solutions. This trait of his is the very flip side of his straightforwardness and passive statement of facts.
On the one hand, such acceptance sounds like willpower, but on the other, it's also conformism for reasons of copium. It would be too difficult for him to fight everything he's long been caught up in; it's easier to pretend he agrees with it. Tsukasa isn't free in the way he's a prisoner of his emotions, repeatedly reaching out to Amane and being rejected; a prisoner of his trauma, which has caused him to develop so many of these strange habits; a prisoner of the demon and Sakura, whose strings he dances to because they don't ask him if he wants to continue working, if he wants to perish forever, only so that some demonic being named Sakura can leave the territory of the Seven Mysteries. Because of the demon, he's also become a stranger to his family, and that wasn't his choice either; he probably didn't expect such a reception at all. Tsukasa suggests to Shijima that she "just stop painting," knowing full well that she can't stop, which is why he came to her for the painting. He himself isn't far behind, unable to stop granting wishes. Tsukasa finds it easier to accept that Amane doesn't love him, but that's okay, that he doesn't mind disappearing, that he doesn't mind fulfilling others' wishes (after all, it so conveniently allows him to try again and again to close the gestalt of granting others happiness), that he chooses what he does. After all, everyone should do what they want!
He says it in the first Sousuke arc, "Everyone should do what they want," and then repeatedly throughout the text. In the Clock keepers' boundary, Tsukasa tells Nene that not destroying yorishiro is also her personal choice. But does Nene have that choice? Tsukasa makes it clear she'll have to go through with it if she's going to refuse, and defeating Tsukasa is truly impossible. Nene ultimately wouldn't have the option to refuse, even if Tsukasa gives her room to maneuver out of respect for her will. And then there's how he just used blackmail on her, but when Nene tries to blackmail Tsukasa, "If you agree to obey me, then," Tsukasa immediately interrupts her.
So he can blackmail other people, but they can't blackmail him, right? But what if Nene does what she wants, why doesn't Tsukasa like that? This runs counter to his plans, and he puts a stop to it, once again demanding Nene be honest in conversation. Although it's still unclear whether he himself will be very honest. Tsukasa talks so much about freedom, but when it comes to truly breaking free from his shackles or agreeing with someone else's opinion that interferes with his plans, it's simply out of the question. It turns out that it's not as simple as someone's true desire, because he forbids that desire, sometimes to himself, sometimes to others, depending on the situation.
6) Copium as a consequence of trauma and the semantic undertones of Tsukasa's behavior.
Tsukasa chooses to accept his circumstances, but inside he still disagrees with them, simply pretending everything is fine. "I want it this way," Amane says in chapter 91, and again, this is Amane's personal will, what he wants. Tsukasa likes to respect others' decisions, right? But he calls his brother selfish. He's still angry that Amane actually does what he wants, sometimes cutting off their lives, sometimes suddenly valuing someone else's. Tsukasa is deeply offended by Amane, but tries to accept everything that comes with it, which results in ambiguous copium methods.
Tsukasa simply subtly taunts Amane. Sometimes he directly says it's strange for him to defend Nene after he's decided to kill himself. Sometimes he constantly suggests someone give Amane a beating. Mitsuba should fight him, not exorcist Kou, no, Amane. This could, of course, be explained by the fact that a test of strength (and it was precisely a test of strength, when Tsukasa assures Mitsuba that he's become strong, he doesn't stop him from expelling the toilet trio from the boundary, which contrasts with how a minute ago he was forcing Mitsuba to fight, and now, that's it, forget it) requires a match with a worthy opponent. But it's as if there's something about a fake person, a false person, a doppelganger, going up against Amane.
This might sound like speculation, coupled with the fact that, as I said, Tsukasa likely doesn't fully understand Amane's motivations, so I won't insist on it. But then we see him encouraging Nene to kill Amane in a perfect scenario. Why would he do that? Nene also started thinking and even came to the conclusion about revenge, which is interesting considering how often her theories about what's going on aren't that far from the truth. "Hanako likes me, Tsukasa and Shijima are in cahoots, Tsukasa is upset with Amane" — which of these is untrue? So, Tsukasa encourages Nene to do this because this way Amane will feel what it's like to be stabbed in the back by the person you love and worked so hard for. Amane won't die in the picture, he's a real mystery, it's purely psychological. Something's hidden in this support for the fight with Amane, one way or another. Tsukasa is also interested in Hananene's relationship, to the point that he interferes in it and ntrs Nene right in front of his brother. He desperately wants to be part of their group, to have some influence there, to receive their attention. Any attention, Tsukasa is glad that Amane is angry about his kiss with Nene, because Tsukasa caused at least such a reaction in him, received at least a drop of attention, took part in their company.
Tsukasa also sublimates his feelings for Mitsuba, constantly repeating Amane's words of forgiveness to him, assuring him that he doesn't hate him even if Mitsuba doesn't ask, caring for Mitsuba tenderly (even if this is only part of the swing in his favor), helping him become strong — because he himself has a control complex, like a kannagi. Tsukasa values strength; he likes to feel it, he revels in it when he goes up against equally strong opponents, like Akane in the boundary of the Firsts, for example. Tsukasa asks him with a certain pleasure, "Show me what you've got, is that all?" And he constantly tries to make the weak Mitsuba able to stand up for himself, teaching Nene the same thing ("you have to try hard yourself to get out," he tells her in the cage). This also ties into how Amane abandoned him, and Tsukasa had to climb out of the boundary again on his own, now as a yorishiro. Tsukasa has learned to rely solely on his own strength and wants to teach his protégé Mitsuba the same, as well as any weaklings he encounters, so they won't be harmed. Ultimately, Tsukasa also agrees that Mitsuba "can become human." It's an impossible dream, but one that Tsukasa nonetheless supports. Perhaps because he himself was half-supernatural, half-human when he returned home and also longed to be able to coexist with ordinary people. Mitsuba wants something similar, and Tsukasa, of course, supports him in this. For his own reasons.
So, what conclusions can we draw from this? Is Tsukasa a chaotic being whose actions cannot be traced back to any pattern? At least partially, that's not true. Tsukasa became who he is not because he was replaced by some fake, but because he himself changed internally after what he experienced. Of course, he now behaves differently, strangely, confusingly, sometimes even unattractively, but there are reasons for this. Tsukasa is a hostage to what he got himself into, and he's still dealing with the consequences. He's a true victim, like the kannagi, but it was this path of acceptance that Tsukasa truly chose himself, the moment he decided to heal Amane. Just as Amane once decided he wouldn't leave and got completely screwed. Yugi are firm in their intentions, but it hardly brings them happiness or any visible results. Nothing changes. Tsukasa, like Amane, is a prisoner of his role, forced to play by someone else's rules, even as he tries to convince himself he's in control. In other words, he's pretending. And this is an important aspect of his personality, revealing who Tsukasa really is. A resentful child, copimg every second of his existence, treating those around him with double standards, having lost his sense of self after the events he's endured. This is Tsukasa now, and we're unlikely to know what he would have been like. Ultimately, Tsukasa is similar to Amane, yet different. And ultimately, he himself isn't ready to transcend his own existence, so we may not see the "solution" to Tsukasa's mystery onscreen for a long time.
