Astra: doom-and-gloom pessimistic emo.
She and Virgil Sanders could be friends. She definitely needs a hug though. Please give her some love.
K.T.: little ball of sunshine.
(idk their pronouns, so apologies in advance) And they can be the one to give Astra a hug. I feel like they just kinda give everyone hugs, regardless of who they are. I feel like they also might have a sweet tooth.
Asuki: strong but silent type.
Bro, why do all of your characters require hugs? What have you put them through? (that's no offense to you, I'm sure you're a fantastic writer) Probably hides their feelings from everyone they care about and then will kinda boil over when things get to be too much.
Dye'a: curious as hell, doesn't know how humans work.
Another hug-giver! Gives off golden retriever energy and probably extremely hyper-active.
Sai'ya: desperately needs a nap, gambles away actual money through online poker games and regrets it the next morning.
Please take a nap, bro. Naps are good. Sleep is healthy. They may need therapy and friends to keep their sleep schedule on track. Also hugs.
Zira: would destroy you for joking about her family, going to the gym is serious business for her.
Ooh, she could kick my ass and I'd thank her. Probably not straight and I respect her. She also can give hugs but they're probably extremely intense and they might break someone's ribs.
