Birth date: November 8 (Scorpio)
Yoshiki comes across as a troublemaker, and honestly, he's struggled at school for a while thanks to stuff going on at home. He was pretty close to just dropping out of Kisaragi Academy altogether—couldn't see the point in showing up if he didn't care anyway. That changed when Ayumi stood up for him against PE teacher Mikio Tsubota. She basically gave him a reason to stick around.
His home situation definitely carries over into how he acts. He's quick to snap when things get frustrating, and while he usually has decent intentions, people around him don't always see it that way. His outbursts and reactions can come off as cold or flat-out selfish, even when that's not really what he's going for.
