The End of the World.After having the Little Busters once again reunited, Riki suggests for them to play baseball, and the others accept. Kyousuke takes one last look at the baseball field as he values how each of the members made an impact in his life. Kyousuke reveals to Riki that they are currently in an artificial world created by him and the others after the field trip tragedy, in which only Riki and Rin survived this bus accident. Kyousuke explains that this artificial world was meant to prepare Riki and Rin to move forward with their lives, so Kyousuke and the others gave the duo a series of trials to have them mature and become stronger. Also during the baseball game, Masato and Kengo each bid their farewells and suddenly vanish after they each confirm their friendship with Riki. After Riki hits a home run, Kyousuke tearfully instructs Riki to take Rin past the school gates back to the real world, as the time for them to part has come. As Riki and Rin run past the school gates, Kyousuke has one last tour around the school before sitting at his desk and disappearing along with the artificial world.
