Kim Joonmyeon didn’t know what to expect when he “stumbled” upon a secret meeting of students in his school’s old, abandoned Janitor’s closet.

He definitely didn’t expect to find out that all of them possess superhuman abilities, whether it be healing, or controlling fire, or even reading minds.

And he REALLY didn’t expect to find out that they were running a secret crime fighting justice club, taking on small neighbourhood culprits with their crazy abilities.

All would have been well and good, if he hadn’t been caught eavesdropping on their latest plans. In order to make sure that Joonmyeon doesn’t run away with the club’s secrets, they force him to become an official member, despite his lack of abilities (he doesn’t really get a say).

Joonmyeon is hopelessly dragged into their adventures, battling vandals, thieves, troublemakers, and a group of shiny guys with bedazzled outfits (don’t ask).

And he really thought that he’d have a normal school year.
