Male. A superhuman who can kick a sliding door into splinters. The school's No. 0 (The Strongest). Appearance: No explanation needed, he's just pure handsome. A perfect human who also excels at studying. Usually never gets angry (the type to smile even if bumped into). But if he does get angry... Lives by the motto "With great power comes great responsibility." A master at breaking up fights between kids.

Male. Kinda handsome. A loser.. an outsider.. The weakest person in history. Extremely clever and resourceful. Twin brother of Alleycat. Threw his grades out the window. Close friends with Young-jjang. Troublemaker 1.

Female. Eternal best friend of Mood-lamp and his brother (Alleycat). (They didn't get along at first, but became very close.) Doesn't have the best personality. An artist?

Female. A superhuman who can overpower Young-jjang with raw strength. A legendary teacher who quit the military due to a bad back; she decided to become a Home Ec teacher after seeing her son fail to even cook plain rice. A literal god that even the delinquents can't touch. She looks like the type who wouldn't be able to control the kids, but looks are deceiving.

Male. Mood-lamp's younger twin brother. Just as skinny as Mood-lamp, but taller and a much better fighter. Threw his grades out the window. Close friends with Young-jjang. Troublemaker 2.

Gender: Who knows? A crazy person who suddenly tried to bully Mood-lamp. He stays quiet around the actual delinquents but hurls insults about people's parents at everyone else.

A collection of all characters who aren't important. (Supporting cast). There's more than just one or two.
