Character Setting

Edit

Akane Koumoto is the principal of Morobare High School, but she looks like a small girl with horns on her head. Actually, she is a many-thousand-year-old devil with amazing supernatural powers, but her personality is childish and playful. She loves sweets so much that she gets angry when she can’t have them. Akane was the teacher of Youko Shiragami’s parents and helps many supernatural students enroll at school. She is very mischievous, enjoys causing trouble, and is often punished by her descendant, Akari Koumoto.

Akane Koumoto appears as a petite female student with horns on her head. She has a small build, standing at 148 centimeters tall and weighing 49 kilograms. Her birthday is January 1st. She has a cute and childlike appearance that does not match her true age, which is several thousand years old.

Akane acts much younger than she really is. She loves playing tricks and jokes and is rarely taken seriously by others. Even though she is the principal, most people can’t believe it at first.

She is a huge fan of sweets. When she can’t get her favorite treats, especially handmade sweets by Nagisa Aizawa, she can become scary and wild. Akane's behavior is sometimes like a spoiled child, but she can occasionally act wise and give good advice.

She likes to peek and snoop around, and enjoys her high status and reputation. But she dislikes ghosts and hates fights about whether to eat mushroom-shaped or bamboo shoot-shaped cookies.

Akane Koumoto is actually a devil who has lived for thousands of years. She worked as a homeroom teacher when Youko Shiragami’s parents were students. Now she works to help many supernatural beings, like Youko, Nagisa Aizawa, Shirou Shishido, and Rin, get into Morobare High School. Akane is also Akari Koumoto's great-great-grandmother.

Akane has incredible devil powers, which include making illusions, creating clones with real bodies, seeing faraway places, and using telekinesis. Even though she is so strong, she usually wastes her powers on pranks and snooping.

She always keeps her promises and follows any contract she agrees to, even if the trade is unfair.

Akane loves to make fun of Akari Koumoto for being single or for her past, but gets scolded or even punished when she goes too far. When Akane finds out that Kousuke Sakurada likes Akari and that they are secretly dating, she gets shocked, tries to use her power to separate them, or even cries about it.

She sometimes quarrels or drinks with Akari, but still manages to give her good advice, like warning her not to drink too much.

Akane also has a tricky relationship with another character named Karen, whom she likes to tease and take advantage of. Still, Akari says Akane only treats Karen better than others.

The Mischief Maker

Akane is often the source of chaos at Morobare High School. She uses her powers to set up strange situations and pranks, sometimes just for her own amusement.

Sweets Addiction

Akane’s love for sweets is legendary. When she runs out of treats, she can become violent while searching for more, especially if her favorite handmade sweets are missing.

Guardian of Supernatural Students

Thanks to Akane's efforts, supernatural students like Youko Shiragami, Nagisa Aizawa, Shirou Shishido, and Rin can attend school safely.

Unbelievable Principal

At first, both staff and students have trouble believing that Akane is really the principal. Her childish attitude and small form make it even harder for everyone to take her seriously.

Advice from Experience

Although she usually acts silly, Akane sometimes notices when Youko Shiragami or Nagisa Aizawa have trouble with their feelings and helps them act more confidently. She also gives important career advice to Asahi Kuromine.

Unusual Sense of Duty

If Akane agrees to a contract, even if the exchange isn’t fair, she always keeps her word.

Trouble with Akari

Akane teases Akari Koumoto a lot and gets punished when she goes too far. When Akari and Sakurada become a couple, Akane tries to use her power to mess with them, but eventually accepts their relationship and warns Akari to drink responsibly.

Akane talks in a bright and cute way to hide her old-fashioned speech. She sometimes shares wise stories, showing her long life experience. Even though she is mostly a prankster, she can act mature when absolutely needed.
