Ataru Mizorogi (溝呂木 辺; Mizorogi Ataru) or most commonly referred to as Mizorogi-sensei (溝呂木先生; Mizorogi-sensei; lit. Professor Mizorogi) by his students is an additional character in the manga and anime series Akuma no Riddle. He was the home room teacher of the 10th year's Black Class at Myojo Academy. He is a civilian, and thus had no idea about the assassination competition that is taking place, or that the students are even assassins in the first place.
Whenever a student is expelled after failing to kill Haru Ichinose, he is told that the student has transferred out due to unknown circumstances.
Personality
He is a very friendly teacher that always wants his students to think of him as a big brother, telling them that they can come to him for help. While his students do not all reciprocate his friendliness, he cares deeply for all of them. He even gets depressed when more and more of the class begins transferring out due to losing the game. However, he attempts to keep his positive and motivated attitude despite the class growing smaller and smaller. He tries his best to teach the remaining students as best as he can. He is quite proud of his job as a teacher and loves to teach his students.
There are moments of pause when he is suspicious of the transferals occurring so often in his class. However, it is revealed that his suspicions are suppressed by Nio's powers. Towards the end of the game, he admits he knows the class is in no way normal. However, as he cannot do anything about it, all he can do is keep teaching.
Appearance
He is a young man who is usually dressed up in blue jeans and a white shirt. His hair and eyes are black.
While at the beach, he wears a Hawaiian patterned shirt that exposes his chest.
Skills and Abilities
Mizorogi is referred to as a civilian, having no involvement in the darker affairs of the class nor the world of assassins. He shows a considerable and avid knowledge in biology. Despite efforts to keep him in the dark, he does pick up on the clues that the class is no ordinary one. However, he is powerless to change anything about it.
