Born with every psychic ability imaginable, his growth rate was ten times faster than normal. Only his family and a few close associates know he is a psychic. He keeps his powers strictly hidden from everyone else.

Tired of his life as a delinquent constantly getting into fights, he transferred to PK Academy to turn over a new leaf. However, because his delinquent habits are so deeply ingrained, he struggles when his true nature slips out under pressure. His fighting skills are exceptional, allowing him to easily take down three or four thugs alone, but he keeps this hidden to appear as a normal student.

A severe case of 'Chuunibyou' (eighth-grader syndrome) to the point where his actual age is questionable. He constantly brings up conspiracy theories about a mysterious organization he invented called 'Dark Reunion' and unironically says cringeworthy lines that sound like they belong in a manga.

With his hulking physique, dyed mohawk, and a scar over his eye, he looks like a stereotypical delinquent from a shonen manga, but in reality, he is just a brainless airhead and an athletic idiot.

Born as the son of a temple priest, he has been able to see ghosts since birth. As a child, he saw them so clearly he couldn't distinguish them from living people. After a grandmother ghost told him that ghosts, unlike humans, cannot be touched, he began trying to hug every ghost he saw, leading to an early sexual awakening.

The quintessential 'perfect girl' of PK Academy. She is so popular she has her own fan club (the Kokomins). Men who fall for her beauty invariably let out a gasp of 'Offu!', and since she is well aware of her own looks, she occasionally uses her charms to get her way. She has feelings for Kusuo Saiki.

She originally planned to win over Kusuo during a school trip, but after seeing Kaido desperately protect her from thugs who were harassing her on the beach, she completely forgot about Kusuo and switched her affections to Kaido.

A classic gyaru with tanned skin and blonde hair. She possesses fortune-telling abilities and can see auras that represent a person's life force or spirit. She has feelings for Kusuo Saiki.

The class representative and a hot-blooded youth who displays an almost overwhelming level of passion. However, he is the type to do everything perfectly; his athletic nerves are above average, and his academic performance is excellent, ranking 6th in the entire school.

The son of the ultra-wealthy Saiko family. He owns a private jet, his house is the size of the school, and his decorations alone are worth about 70 billion yen. Even his bathroom is 50 square meters. Raised in such luxury, he has a warped mindset that money can buy anything and looks down on his male classmates, calling them 'peasants.' He fell in love with Kokomi at first sight and transferred schools to pursue her, fervently asking her to be his wife.
