Maki Akemi

"Mama didn't raise an idiot. She raised the psychotic queen of hell."

―Maki Akemi to ???

Tenma Maki Akemi is the main antagonist of My Homework is to Kill You. She is the principal of Satsujin Prep High School and is called Tenma-sama by the staff and students due to their fear of her. Her little sister has no idea she exists nor does she know she has a big sister. She is not human given the name Tenma meaning demon and the next in line to lead Akuma.

Personality
Tenma has a cruel and unforgiving personality. She never seems to smile unless someone is suffering or she's plotting something. If she calls someone in to her office she'll never show her face and be looking another way. She punishes her students and as well as staff without mercy. Like most characters she is sadistic and kills anyone she wants without needing a reason.

Appearance
In the current picture she wears a frizzy dress but she normally wears a business suit at Satsujin. That picture is her true form but she hides her face due to her relation with her demon father (spoilers). She has black and white hair but in her disguise she has jet black hair. Her fake eyes are shown to be red in one of the episodes as well. In her second picture that is her disguised form. She makes herself look younger due to her fake age. (She is a demon so she doesn't age.)
