Oohh so about your ocs (I'm gonna go with BBBB but don't mind hearing about anyone!) What's something they each really love? What's something that drives them crazy?
I'm sorry this is stupid late, I just really wanted to think long and hard about this.
What he loves: The whole bosozoku aesthetic, obviously. There's no real way I can see him existing like that if he's not a nerd about vintage stuff on some level. Motorcycles and rock n' roll, baby.
What drives him crazy: People that prey on the meek, it's a big berserk button. In fact, it's the entire reason why The Strikin' Vipers exist in the first place. Princess Primrose is also a huge nuisance to him when she first shows up, but they eventually get along.
What he loves: The Strikin' Vipers in general, but particularly Akio. He really cannot imagine his life without him.
What drives him crazy: His family. Dad's a big businessman that owns a lot of the shit in town. They very much do not want him to be part of a gang, not out of concern for his safety but because it makes them look bad. They can't seem to get a leash on him no matter how much they try, though.
What he loves: His big sister, embroidery, attention, stabbing
What drives him crazy: Akio. They butt heads quite a bit, as he much prefers more aggressive approaches to defending their territory and the like. He's the lancer, what else do you expect from him?
What he loves: Anything action, particularly battle anime, or fantasy. He's probably the most stereotypically geeky of them in terms of interests.
What drives him crazy: Rules that make no sense and the people that try to control him with them
What he loves: Ducks! There's a pond near the shrine where his family lives and there's been ducks around ever since he was small. It extends to affection towards birds in general, so he's good friends with Primrose before he's in on the whole Bride's Bouquet business.
What drives him crazy: People who are quick to judge based on looks. Also, stairs.
