Platonic Love:

Yuu and Floyd was a surprise friendship that no one in NRC understands how it happened, mostly because of how they met. During the fight in Mostro Lounge, Yuu punched Floyd in the gut and sent him wheezing to the ground. Floyd has decided to latch onto her ever since and they grew into fast friends from there.

Yuu and Jamil's friendship was probably the longest it took to fix. Starting out from: acquaintances, to being dislike, then back to acquaintance, a very slow climb into becoming friends, and then finally a shift into Platonic Love. She straight up kept calling him "Viper" until the end of book 5. Jamil no longer sees Yuu as a nuisance, but the two sometimes mess with each other and often Jamil goes to Ramshackle to relax (and escape Kalim).

Yuu and Idia are video game buddies. He was shy around her at first, until he learned of her gaming knowledge, now they both complain about their SR and UR luck. Idia invites Yuu over for gaming tournaments and she is a menace in any team match. They've gotten so close that, when playing any team game, most of the time they don't need to call out to each other to handle a problem.

Dislike:

Yuu and Malleus's friendship tanked after the events of his overblot. She was hurt, but mostly she was furious with Malleus for going as far as he did and for endangering others with his selfish need to keep everything the same. She switched to calling him "Draconia" and has made no effort to rekindle that friendship. Malleus had hoped she had changed her mind, but realizes that he had lost his only friend to what he had done.
