Atsushi Doujou Husbando

First Lieutenant librarian. Captain of the special unit "Dojo Squad". Superior in combat and normal library office work. Has quite a short figure compared to men in his age, but that never makes him weaker than the others. Dojo is a strict leader and has a straight character. He always pushes his subordinates (especially Iku Kasahara) to their limit. His straight character makes himself a good prey of teasing by other officers. He is usually calm and composed, but not whenever it's concerning Iku. She often calls him "a devil" and he is very tough, in part, because he sees his old self in her, but he also often worries about Kasahara and even defends her.
