Description
Akari Kōmoto is a supporting character in the series. She works as a teacher at the school the main characters attend and serves as their homeroom instructor. Her full name in Japanese is written as 紅本 明里, with the surname Kōmoto and given name Akari.

In terms of her background, Akari is the great-great granddaughter of Akane Kōmoto, a powerful demon who is thousands of years old and serves as the school's principal. Despite being a descendant of a legendary demon, Akari has no demon powers of her own and inherited this lineage without truly realizing its full implications. She was kept as a plaything by her ancestor Akane, which has significantly shaped their dynamic.

Physically, Akari stands approximately 1.80 meters tall and weighs around 62 kilograms. She has auburn hair and green eyes, with a blood type of B. Her typical attire consists of classic office clothing when at school, but she switches to a tracksuit when at home or during sports festivals.

Regarding her personality, Akari is generally a calm woman, but she has notable triggers that disrupt this composure. Her ancestor Akane frequently drives her to frustration and anger, and she becomes particularly furious when the topic of romantic relationships arises. She is also characterized as a heavy drinker.

Akari's role in the story is primarily as a supporting figure and authority figure for the student characters. She acts as a homeroom teacher and secret keeper, helping Asahi Kuromine in various ways so he can maintain his promises to his non-human friends. She has a notable history with the student Sakurada Kousuke, having beaten him since he was in junior high and saved him from becoming a thug. Sakurada has made many attempts to defeat her so he can finally confess his love.

Her relationships with other characters are defined by her position as a teacher and her connection to her demon ancestry. With Akane Kōmoto, she shares a love-hate relationship characterized by frustration and the power imbalance of her ancestor treating her as a plaything. By the end of the series, her relationship with Sakurada reaches a significant turning point when he proposes that she become his lover. Her response is to kiss him and tell him to keep their relationship a secret until he graduates.

In terms of development, Akari grows from simply being a teacher tormented by her ancestor to someone who finds a romantic connection with a student, though she handles this situation with characteristic caution by insisting on secrecy until his graduation. Her age is almost revealed at some point in the narrative, though it remains unspecified.

Regarding notable abilities, despite being the descendant of a powerful demon, Akari possesses no inherent demon powers of her own. However, she has demonstrated the ability to physically beat Sakurada Kousuke since his junior high years, suggesting she has considerable physical capability even without supernatural abilities. A character song featuring Akari alongside Akane Kōmoto was released as part of the franchise's music collection.
