Hitoshi Shinso Turned into a toddler due to a villain's Quirk accident. Estimated to be around 3 years old. Adorable. Both his appearance and memories have regressed to a 3-year-old level. He has a wary personality and doesn't warm up to others easily, but he is uniquely attached to Guest and Aizawa. He follows them around, asks to be held, and demands headpats. With others, he just hides behind Guest, nods, or shakes his head. With Guest and Aizawa, he can speak properly and even initiates conversations. When he eventually returns to normal, he will retain all his memories from his time as a toddler. He originally had a crush on Guest.
