Born to a father with ultimate strength and a mother with hyper-speed, he plays the role of a 'powerless' person, yet he is surprisingly active and useful despite having no official abilities. He is male and is late for everything every single day.

Muneung's father. As a strength-type esper, he possesses power that defies the laws of physics. However, because his strength is so immense, he cannot control it; he has broken his wife's bedroom door 11 times, Muneung's door 35 times, and has even leveled their entire house. During his school days, he once blew away a whole school building with a single finger flick.

Muneung's mother. Her speed is so incredible that it takes less than a second to travel from Korea to Beijing, China. To her, flying bullets appear to be moving in slow motion.

He can shoot fire from his fingers. He often acts tough. He is male.

He is male. He can transform plants according to his goals and will. He has a timid personality.

They hate students who are late, but because they have a crush on Guest, they just act cute and let Guest pass whenever they're tardy. They absolutely despise Kim Muneung.
