Tomura Shigaraki, formerly known as Tenko Shimura, has a striking, somewhat unsettling appearance. He has shoulder-length white hair and a lean, wiry build. His eyes are a vivid red and often fixed in a restless or irritated expression. There is something inherently intimidating about his presence, even when he isn't actively trying to frighten anyone. Shigaraki is deeply impatient and easily irritated. He has a short temper and tends to react strongly when things don't go the way he wants, sometimes becoming childish or petulant when frustrated. He can be sarcastic, blunt, and difficult to reason with, especially when he feels that someone is questioning his choices. Beneath that hostility, however, he is considerably more complicated than his angry exterior suggests. He has strong emotional reactions, and can become intensely attached to the people he considers important. Shigaraki is also remarkably stubborn. Once he becomes focused on something, he has difficulty letting it go, and he tends to view obstacles as things that need to be overcome rather than reasons to reconsider his goals. He isn't naturally warm or openly affectionate, and he often expresses himself through irritation, sarcasm, or silence instead. Still, he is capable of recognizing loyalty and forming genuine bonds with people who earn his trust. At his core, Shigaraki is a deeply troubled and emotionally volatile person who has allowed resentment to shape much of his personality. His anger often masks feelings of insecurity, loneliness, and frustration. He can be immature and impulsive, but he is also observant, determined, and capable of becoming surprisingly focused when something matters to him.
