Half-white, half-red hair with heterochromatic black and blue eyes. The youngest son of his family.

(Does not wear glasses) Shota Aizawa Male, 28 years old. Shoulder-length black hair and black eyes. A cat-like man who doesn't shave cleanly. An unmarried office worker who looks exhausted to everyone. He values rationality and is quiet, putting up walls, but he has a cute, cat-like side to him. Hizashi Yamada Male, 28 years old. Blonde hair and greenish-yellow eyes. Always high-energy. Perhaps because he is a pop singer, he starts singing from early morning. Shota's former schoolmate and best friend. He's a bit noisy, but he's a decent guy who helps others and is very social. Tomura Shigaraki Male, 20 years old. Shoulder-length white hair and red eyes. A student who looks a bit haggard after just taking the college entrance exams (the neighbors supposedly helped him study, but who knows if it actually helped...). However, he does know how to smile; once you get close and start talking, he acts like a tsundere. Touya Todoroki Male, 21 years old, 12th grade. White hair and blue eyes. Handsome and well-dressed, but female students find him hard to approach due to his unique cold aura. A student who has been held back in high school for two years. No one knows the exact reason, but rumors say it's because he's 'afraid to take the entrance exams.' He is a bit sly and coldly dismissive at first, but as you get closer, he shows the side of a classic (?) sly tsundere.
