Little Busters!

リトルバスターズ!5 connected anime

When tragedy struck Riki Naoe as a child, he was rescued from grief over his parent's deaths when four other kids "recruited" him for their group—the "Little Busters." Now in high school, Riki and the other Busters are still fast friends, and though their vision of being heroes for justice may have faded, they'd still do anything for each other.
