Okay, so everyone assumes that Rin is stronger than Yukio. He’s a half-demon, inherited Satan’s flames and Mephisto gave him a cool sword. Rin is openly demonic. Satan thinks that Rin is going to be his new vessel, but Satan’s going to get a rude awakening. He thinks Yukio isn’t a threat, he’s just a weakling and a window Satan can use to watch his more powerful son. Yukio is only human after all…..
Yukio physically takes after his mother. She had long exposure to Satan since childhood and it made her body resilient. This is why she was able to bear Satan’s children. Yukio is like Yuri. He’s human but extra strong and Satan can’t hurt him or possess him. Is Satan safe from Yukio….nope. Satan is in danger.
Yukio has the same sort of powers that Todo does. Todo (a demon-eater) was able to harness the powers of the demons and maintain his consciousness. Todo remained himself, forcing demons to acclimate to his body until they synched. Todo was the master over the demon’s power and the demon was just an unwilling passenger.
If the same is true about Yukio (which Todo seems to believe), then Yukio is a demon-eater.
Yukio hasn’t inherited Satan’s power, but he will eventually become the master over Satan and will become the next great power of Gehenna. Yukio will not be possessed by Satan but has the potential to be his replacement. Satan thinks he’s using Yukio, but slowly Yukio will take control of Satan. This is why all the flames of Gehenna can’t harm him.
If Yukio gives in to his dark side; He could become the next big bad. He has a hell of a temper and dangerous. Not only that but he’s super smart. The other demon kings would be forced to bow to Yukio and would have a difficult time outsmarting him.
Perhaps this is why Mephisto is plotting against Yukio, he’s a bigger threat than Lucifer or even Satan. Mephisto has tried many times to get through to the Yukio but hasn’t had any luck. Yukio is so obsessed with power, and he’s stubborn as a mule. He’s emotionally just like Shiro after all.
The question is…would Yukio willingly choose power over the lives of his friends? Shura seems to think so…and she’s worried.
but I think Mephisto has changed his mind on the matter. Yukio didn’t shoot him, so perhaps he can be redeemed? The timeline for Yukio changed, which surprised Mephisto, but will that difference matter? Mephisto has seen all of this happen before. It mirrors the development of Shiro, the once mean and cruel exorcist was eventually capable of love. Maybe the apple doesn’t fall too far from the tree.
When we take a look at Yukio’s emblem. We see a scale, a scale with plants on one side.
Shiemi is the key to winning Yukio back. She is going to have an even worse time than Yuri. Yukio and Satan….they’re going to be the same person. Satan totally noticed Shiemi too…because hell…she reminds him of someone doesn’t she?
If Satan wants to get his freedom back, Lucifer would have to kill Yukio’s consciousness to release his father from servitude. Then Satan is stuck with a second problem; if a demon is forced out of a close bond with a human, the demon can be weakened substantially. If Satan tried to yeet himself into Rin (his preferred vessel), Rin might be able to overpower him and send him Shiro-style back to Gehenna.
However, it plays out. It is going to be fantastically entertaining. Yukio is going to be far more interesting than I originally thought.
