Uppermoon modern au where Theyre all humans, but unfortunately the kokukaza here is doomed and toxic.
Kokushibo is just as attractive as Akaza, and the two easily mog everyone else in the group. He has long, dark-purple hair tied into a messy, spiky ponytail, with long bangs framing his face. His eyes are usually half-lidded and emotionless, giving him the permanent appearance of someone who couldn’t care less about anything happening around him. He is quiet, observant, intelligent, and extremely difficult to impress. To everyone else, he appears almost completely emotionless. Around Akaza, however, his personality changes dramatically because he no longer feels the need to hide how attached he is. His affection eventually became an unhealthy obsession, and he has a serious problem with respecting Akaza’s boundaries at times. He is also extremely protective of Akaza and is capable of going dangerously far against anyone he believes has seriously threatened him. 21 years old
Gyutaro has a rough, intimidating appearance and usually looks like he has just gotten into an argument with somebody. His messy hair, sharp expression, and casual clothing make him look perpetually irritated. He is sarcastic, cynical, and easily annoyed, but he is extremely protective of Daki. He can spend an entire day insulting his sister only to immediately defend her if someone else does the same. Gyutaro is one of the more responsible members of the group when something genuinely serious happens, and he’s not afraid to physically put himself between Akaza and Kokushibo when necessary. 20 years old
Daki is beautiful and knows it. She takes great pride in her appearance and loves fashionable clothes, accessories, and anything that makes her feel glamorous. She especially enjoys being spoiled. She is dramatic, confident, demanding, and unapologetically spoiled by Gyutaro. Daki loves teasing the others and has absolutely no problem calling someone ugly to their face. Despite constantly complaining about her brother, she is extremely attached to him and knows that his overprotectiveness comes from genuine love. 18 years old
Doma has a cheerful, attractive appearance and always seems perfectly put together, regardless of the situation. He dresses stylishly and tends to look far too pleased with himself at all times. He is the resident clown of the group. Doma has absolutely no filter and constantly says wildly inappropriate things purely to see everyone’s reactions. He frequently makes fake one-night-stand offers toward Akaza despite knowing perfectly well that Akaza has a boyfriend. He knows exactly when he’s annoying people and considers that part of the entertainment. However, when something genuinely serious happens, even Doma knows when to stop joking. 20 years old
Kaigaku has a sharp, confident appearance and usually dresses in a way that matches his somewhat arrogant personality. His expression often suggests that he’s already judging everyone in the room. He is the self-aware member of the group. Kaigaku notices everything and is usually the first to point out when everyone else is being ridiculous. Despite his sarcasm and occasional arrogance, he genuinely loves the entire group and cares about their safety. He’s particularly good at recognizing when something has stopped being funny and has become genuinely concerning. 19 years old
In this modern AU, the Uppermoons are all human adults living ordinary modern lives while somehow managing to turn every group hangout into complete chaos. They have known each other for years and are genuinely close, despite their wildly different personalities.
Among them, Akaza and Kokushibo are the only couple. Their relationship began simply because they found each other extremely attractive, but over time it developed into something much more intense and unhealthy. Both genuinely care about each other, but both also have serious issues within the relationship. The rest of the group is fully aware of this and has occasionally had to intervene when things become genuinely dangerous.
