I've been wanting to go in-depth about Niigokasa's relationships with the rest of the Niigo for a while, so I'm finally doing it, no more procrastination for this lmao
While I rated their relationships from 1-10, no one reaches 10 nor does anyone reach close to 5 or below since naturally, Niigokasa is close to each of the members somewhat. I mainly used this because there are a few more characters with relationships to Niigokasa I wanna touch on in the future which uhh might be in a long time since some of them happen/improve after the Niigokasa events I thought of (yes I did think of two full Niigokasa event stories but I still haven't started writing them yet despite having all the groundwork laid out lmao Go me- Maybe I'll make another post talking about them if people are that curious lol)
Anyways, besides that, also tried making semi-Kizuna ranks for this so that's nice, behold my terrible editing skills and there might be quite a lot of stuff that might contradict canon but ugh whatever lol (these are also kinda long so better viewed on a computer probably lol)
Before their first proper meeting in the Empty Sekai, they semi-knew each other from school albeit without Mizuki knowing Tsukasa was Kōu (Tsukasa's online name - Translation: Rainfall) due to his personality at school being extremely different and his tone of voice on Nightcord is much quieter and softer like he'll fall asleep at any moment.
On the other hand, Tsukasa did know that Amia was Mizuki due to recognizing their voice and the accessories Mizuki sometimes wore to school that he made for them himself as Kōu. (He sent them in letters to a post office near Mizuki's house.) Upon their meeting in the Empty Sekai, Mizuki was surprised knowing their senpai at school was Kōu while Tsukasa had to explain why he wasn't surprised about Amia being Mizuki. Despite describing this exhausting aura they feel from Tsukasa, especially with his eye bags and dead-like tired eyes, Mizuki does say that the smile he has feels the same as the ones at school, warm and genuine usually.
After the events of the main story, Mizuki starts going to school more frequently to meet Tsukasa, saying that besides having to go for attendance, they mainly go to hang out with him which warms Tsukasa's heart. Though the first few meetings are a little uneasy since Mizuki knows of Tsukasa's "true" personality, they quickly get along with him and actually start seeing the cracks with Tsukasa at school that must have been there all along. Mizuki starts seeing the work overload Tsukasa burdens himself with especially for the Theatre Club and when learning that Tsukasa is friends with Rui due to them both being in the Theatre club and asking if Rui knows, he says no with a feeling of detachment Mizuki picks up on easily and feels as well themselves personally. They worry for him a lot due to his overworking despite Tsukasa saying he'll be fine.
In their free time (or more like Mizuki pulling Tsukasa away from his work so he doesn't overwork himself to death), both at school and in the Empty Sekai, they like to create accessories for each other in person and pick up sewing tips from one another. Mizuki even decorated and braided some of Tsukasa's hair one time while adding cat ears to both of their heads so they can match. Tsukasa enjoyed it a lot though Ena who was there at the time thought it was overkill. Mizuki drags Ena to school during the day sometimes so they can watch Tsukasa's performances which Tsukasa is very grateful for.
They first met online a few months before the events of the main story. When Kanade was losing inspiration for her next song, Mafuyu tried recommending looking at other people's works for inspiration this time around, so while looking at piano covers for melody inspiration, she ran into Tsukasa's piano channel via one of his covers being one of Niigo's songs. Kanade described his covers as bittersweet for some songs and downright depressing for others, sometimes feeling like his covers were cries for help. He even had some original piano songs that enhanced those feelings more along with showing Kanade that he knew how to make ear-catching yet heart-string-pulling melodies.
After being able to get ahold of Tsukasa via Nightcord, they started working together in little sessions that eventually concluded with Kanade getting Tsukasa to join Niigo. Though Tsukasa himself feels like he's not much help with the music writing process, Kanade reassures him that the melodies that he writes and entrusts to Kanade do wonders for their songs.
When first meeting in the Empty Sekai, like Mizuki, Kanade points out Tsukasa's exhausted expression and immediately shows worry for him. Tsukasa brushes it off saying that he's looked like this for years, though he personally can't tell if it's gotten worse lately. She assumes that he overworks himself just like her but due to doing so herself, Kanade felt like she didn't have much say in that regard. Even so, both of them constantly tell each other to sleep more and they only listen to each other about half the time.
After being able to create a piano melody that Mafuyu described as warm, Tsukasa entrusted the melody to Kanade and silently showed he wants to make a song that saves Mafuyu as well.
They mainly meet each other in the Empty Sekai where Kanade sometimes finds Tsukasa sleeping. She at first thought he was trying to disappear like Mafuyu (and later on Ena) but Tsukasa actually states that sometimes it's too painful for him to rest in his own house, so he comes to the Sekai to rest instead. While not fully understanding it at first and becoming worried for him again, she's glad that the Sekai can be sort of a safe haven for him and that he is at least getting some rest outside of their meetings. When meeting in person, Kanade occasionally uses Tsukasa for shade on bright days due to their height difference and is happy he doesn't mind.
Before first meeting in the Empty Sekai (and continuing afterward), Tsukasa always compliments Ena's artworks and describes the feelings he gets from them, even if they're different from what Ena had initially intended. Though he apologizes for the misconceptions, Ena says it's alright knowing that art can take many forms in the eyes of a viewer and actually takes this as a visual storytelling critique that she uses to change the drawings to better suit what she had in mind originally.
After meeting in the Empty Sekai, she realizes that Tsukasa looks like someone she saw during the times she would occasionally go to school during the day and properly met him for the first time in person when Mizuki took her to one of his school performances. Ena feels off-put by his louder and hyperactive personality at school, especially since outside of the times they meet at school, he's always his more calm and tired self. She does learn that Tsukasa actually wears some heavy foundation to cover up his otherwise noticeable eye bags and wonders if she should get some of the products he uses herself with all the comments Mizuki keeps making about the eye bags that are supposedly appearing on her face.
They also semi-relate to having troubled sibling relationships though Ena only states that they banter a lot mostly similar to how Ena banters back at Mizuki whenever they try to tease her. Upon receiving the question about how Tsukasa's relationship is with his sibling, he stays silent before saying he doesn't want to talk about it in a pained voice that Ena picks up on. She understands him not wanting to talk about it, which Tsukasa is grateful for.
After meeting the "true" Mafuyu in the Empty Sekai, Tsukasa could already feel an emotional connection to Mafuyu, especially after the mentions of wanting to disappear. Though he doesn't mention it, he agrees with Mafuyu's statement and stays silent once Miku sends him and the rest of the members besides Mafuyu herself. Deep inside, he doesn't want Mafuyu to disappear though. This makes him remember the guilt and pain he has gone through for years regarding his feelings of wanting to disappear.
Whenever they meet each other in the Empty Sekai, they usually don't have much to talk about besides music. When asking if anyone knows of the Tsukasa Niigo knows of, Tsukasa does state there is one person who does know this side of him and actively supports him through it. Sometimes Tsukasa feels for the troubled relationship Mafuyu has with mainly her mother, knowing how it feels to try and live up to their expectations to make his own parents happy despite their constant absence.
When Mafuyu got to meet the Tsukasa who acted hyperactively, she felt a connection that Tsukasa first felt when he got to start learning about the real Mafuyu. They both relate to each other by acting for other people and wanting to please others, but unlike Mafuyu, Tsukasa does have passions that he chases after and things he likes to do despite how worn down he is. While respectful of him, this makes Mafuyu feel slightly envious of Tsukasa being able to have a true self outside of his acting compared to her and wonders if she'll ever find her own true self. Whenever Mafuyu goes even through the slightest change, Tsukasa notices it immediately and feels happy for her even if he doesn't state so verbally most of the time.
Andddd I'm done! (for now lmao) I feel like there's so much more stuff I could have written for all the characters, especially taking into consideration one of the Niigokasa events I thought of, but I attempted to keep it out of this post at least lol Sorry if there are lots of spelling/grammar mistakes or some parts are just me going on a ramble, especially for the Mafuyu section. I found myself just trying to put down whatever I thought of at this point knowing how long I spent trying to write each section. I also wanted to allude to Niigokasa's character even more since I honestly haven't done so at all even with my art or the introduction I posted for him a long time ago, so hopefully, this hypes up any future content I decide to make of him lmao
Once again, tysm to everyone who read through all this!
