Shun Morita (森田 俊,Morita Shun?) is a second year high school student and a main character in Blood School.
Shun has short, dark brown hair with a fringe that sweeps off to the left, and some strands sticking out at the sides. He also has light brown eyes and square, light green glasses. Like the other boys at his school, he wears a yellow blazer, dark brownish-red slacks, a white long-sleeved shirt, a bright red tie, and brown shoes.
Shun is a very no-nonsense, intelligent boy, but can prone to panic or get antsy when frightened. He and Kaito have a very cat/dog-like relationship and it's not uncommon to see the two of them arguing with each other, but he deeply cares about Kaito underneath all this. He likes to tutor his friends and help them when they're stuck. Without him, the group would never be able to escape the old schoolhouse, or solve the mystery behind it.
