Little Busters!

A group of friends known as the Little Busters help Riki overcome his grief after his parents' death, but their bond is put to the test as they face various challenges.

Riki was a child when his parents died, leaving him hopeless and depressed. What saved him was a group of four kids calling themselves the Little Busters. They took Riki out and played with him during his time of need. He really enjoyed being together with them, and his grief gradually faded away. Now in his second year of high school they still hang out, fight and live together, and enjoy their school life.
