Karma's got a reputation around school as the violent troublemaker, and honestly, it's earned. A teacher betrayed his trust back in the main building, which basically poisoned his view of all adults—he has almost no respect for them now. He's frighteningly good at fighting, manipulation, and weaponry, and he genuinely enjoys causing problems. He's one of the few students who's actually managed to hurt Korosensei.
On the surface, Karasuma pegged him as lazy, but there's mischief written all over his face. Karma skips boring stuff like assemblies without blinking, and when he actually fights, he gets vicious—no hesitation about roughing up anyone who threatens him or his Class E friends. But underneath the casual attitude, he's ranked 4th academically out of 186 students school-wide, which tells you something.
Despite being strong across the board, he doesn't excel at any one assassination technique. Instead, he wins through tricks and psychological games. Itona described some kind of "vision" Karma has that makes him genuinely dangerous. He loves humiliating opponents more than actually finishing them off.
What's interesting is that Karma actually has solid principles. He got sent to Class E for standing up for a senior being bullied by main building students—he didn't look down on them like everyone else did. And while he plays the lazy card, he's proved he can buckle down and study hard when it matters; he just hides it by pretending he's gaming instead.
