Little Busters!

After losing his parents, Riki Naoe withdrew from the world until the energetic Kyousuke Natsume pulled him into a group of friends called the Little Busters. Years later, Riki, Kyousuke, Rin, Masato, and Kengo are still together in high school, but graduation is approaching and Kyousuke decides they need one last shared goal: forming a baseball team.

Riki begins recruiting new members, drawing several girls with their own worries into the group that once saved him. Then Rin receives strange messages asking them to complete tasks and uncover the secret of the world. What seems like another game among friends gradually suggests that their happy school days are hiding something none of them is ready to remember.
