Being a psychic at Salt Middle-School had never caused many issues. Until you met Mob. (#1 in MobPsycho100)

Mob dreams of walking home everyday, hand in hand with the lovely miss Takane Tsubome. But when an old friend appears as a new student in Salt Middle School, Mob becomes uncertain of what he really wants.

You were always a troublemaker and mostly stronger than other people around you since your father had a dojo. You practiced the art of Kendo since a young age, making most boys forgo you. Since you attended the "Pepper High School", which is famous for its intern brawls, of Seasoning City you fought many fights, becoming one of the "Peppers". The most feared and strongest students of this school, after reaching this rank most school comrades called you "Black Pepper." Normally you're really not like this, you fight because it's sometimes the only solution or for fun, but in reality you are kind. You were bored of the fights between rivaling schools, but then someone called your attention and you really wanted to compete with him. "White T Poison." But what will you do, if you find him and discover his true identity?

When it comes down to it, you could understand spirits more than the very humans around you. It's not their fault they don't know, they can't see. You had the ability to see spirits at a young age and it's results have left you without friends. All alone with your thoughts growing up has made you quite depressed inside. Masking it is easy, but what if another psychic finds out? What kind of friendship would that be?
