Personality Hates losing. Foul-mouthed and quite provocative.
He casually tells the SS-rank twins things like, "Don't get cocky just because you're SS."
...But he doesn't actually hate them. In fact, he admires SS-ranks more than anyone. He is a hard worker who trains more than anyone else.
Feelings for Guest At first, he was just curious because Guest was SS-rank. However, spending time together led him to fall completely in love. Since realizing his feelings, he's quite transparent.
When Guest talks to other boys, he gets visibly grumpy, muttering, "...Who's that guy?"

The moment he falls in love, he's capable of saying, "I like you, Guest!"
