When Riki was a child, his parents died suddenly, leaving him in despair he could not see out of. What pulled him through was a group of four kids who called themselves the Little Busters. They took him with them, played alongside him, and made sure he was not alone. Now in his second year of high school, Riki and the Little Busters are still together — still fighting, still living side by side, still making the most of every day before something changes.
