kasane teto - age 15, she/they/it nonbinary lesbian. very sociable and talkative, causing more introverted people to see her as annoying. she loves to tease her friends and play pranks. she doesn't have a very good sense of boundaries. she has little fangs
yokune ruko - age 12-14, she/her bi trans girl. i'm keeping her height as 6'5" because i think it's funny. sleepy and has no thoughts. she's not really shy, but sometimes she comes off that way in conversations because she spaces out too much to contribute much. generally very optimistic and loves her friends.
namine ritsu - age 12-14, he/she/they gay trans boy. pissed off most of the time. he refuses to admit that he likes and cares about his friends, he's really only openly caring toward ruko his best friend. has a less mature sense of humor as expected of his age. his special interest is mega man but you have to be at like level 10 friendship with him to know that
sukone tei - age 19, she/her aro lesbian. she doesn't really leave the house unless her friends force her to. even though she's not very talkative she is very protective of these kids and is willing to kill anyone who hurts them. people who don't know her well think she's creepy because she walks kinda stiffly and speaks pretty monotone but her friends are 100% used to her demeanor and don't acknowledge any of her oddities at all.
ooka miko - age 14-15, she/they non-binary girl (anything more specific is unknown). she tawks like dis in weal life owo. very childlike and softspoken and doesn't talk about herself much, prefers to ask lots of questions about other people. also depending on the universe i depict her in she is sometimes a werewolf but she doesn't talk about. not because it's a secret but because she doesn't think it's important
rook - age 13-15, he/him ??? guy. the other vippers just kinda vaguely know him in passing. ruko's the only one who regularly hangs out with him because she's his "big sister" (she is younger). no one believes him when he says he can become a dog. he probably lives in the basement.
there's other vipperloids but i'm tired
