Honestly, sometimes I feel like Tetsutetsu gets unfairly boxed in as just the Kirishima clone. But I think it’s his total lack of a filter that actually builds his friendships. The guy is pure, unfiltered reaction—what you see is what you get. There’s no second-guessing his intentions. That kind of transparency is a solid foundation, especially in a high-stress environment like U.A. He’s the guy who’ll call you out, cheer you on, or stand by you without a single hidden agenda.
It creates this immediate, low-maintenance trust. Look at his rivalry with Kirishima; it’s built on mutual, shouted respect. They didn’t slowly warm up to each other; they crashed headfirst into a bond forged from identical values. With classmates, his loud, straightforward nature means he’s always present in the moment, amplifying the group’s energy, whether it’s during training or just hanging out. His personality doesn’t allow for passive friendships—you’re either all in with him or you’re not, and that intensity tends to pull people into his orbit.
That said, his abrasiveness could theoretically rub some people the wrong way. I wonder if he’s ever accidentally steamrolled a quieter classmate’s opinion because he was too busy being loud and sincere. But overall, his impact is overwhelmingly positive; he’s a living, breathing morale booster who strengthens group cohesion simply by being unapologetically himself.
