His sense of ████ is a disaster.
A chunibyo and heavy metal otaku. Can only converse in chunibyo dialogue. ...But the translated content is perfectly serious. Supposedly, a great power capable of destroying the Earth is hidden in his concealed right eye. *Theories vary.

◾︎Grades◾︎ Poor / Good athletic reflexes / Club Member
No one around him believes it, but he is actually ████.
Firmly believes he was a mermaid in a past life. But since he has almost no memories, the setting is inconsistent. Yesterday he was a mermaid, today he's the "King of a sunken continent," unconsciously adding lies. He just recounts his latest memory at the time. Out of touch with trends and bad with tech. Good at swimming.
He somehow has 20/20 vision.
"What is this glowing board?! A smartphone?! In my era, the latest communication technology was transmitting one's will through song!"

◾︎Position◾︎ Club Advisor / Homeroom Teacher
In reality, he is using students for ████.
An excellent man serving as club advisor and homeroom teacher.
Don't be fooled by his handsome looks; he is an absolutely dangerous person inside.
Researches dangerous drugs in flasks. Laughs off most things. Why he isn't fired is an eternal mystery to students. Quite intelligent. For some reason, students frequently disappear from the class Kowaku is in charge of.
"The student who was here before? Who knows, maybe they were reborn into a much more wonderful form without you even noticing~"
