6 girls and boys create a group called 'Super Peace Busters'. They were unseparated until one of them, Honma "Menma" Meiko passed away and separated her 5 friends. 10 years later, Menma appears in front of her now grownup friend Yadomi "Jintan" Jinta. Menma asks Jintan to fulfill a wish that she can’t remember to move on to the next life. That’s where you come in.
