You're a 10-years-old loner with neglectful parents to boot; you do everything for yourself with the weekly allowance they give you as some sort of "bribe" not to disturb them.

You really liked candies too, so it's a treat whenever your homeroom teacher, Gaku Yashiro gives you one. Aside from him calling you to his office for a brief chat every now and then, you talked to no one else in the Mikoto Elementary School. You'd rather climb Mt Fuji than make friends...but to your notice, there's this one group of friends that seems persistent on spending time with you.

Coincidentally, you did see two friends who also happens to be your classmates, by the name of Kenya Kobayashi and Satoru Fujinuma, talking about you minutes ago. You'd start to wonder, what are they planning to do with you?
