Story
The protagonist, Riki Naoe, suffered the loss of both parents when he was a child and was in despair.
He was saved at that time by a group of kids who called themselves the Little Busters (Kyousuke Natsume, Masato Inohara, Kengo Miyazawa, and Rin Natsume).
They took Riki with them and went around making various things into villains and punishing them.
They were idiots, and they always ended up beaten at their own game, but it was a lot of fun. When he was with them, the loneliness and pain eventually healed.
Like this, time passed and they entered the same school, and now they are in their second year.
Even today, under Kyousuke's suggestion, they continue to be fools and run full speed with their youth.
