After having the Little Busters once again reunited, Riki suggests for them to play baseball, and the others accept. During the match, Kyousuke reveals to Riki all the truth about the world they're currently living in.
Having assembled the rest of the original Little Busters, Riki intends to save Kyousuke from despair the same way he did for him when his parents died. Meanwhile, Kyousuke reminisces that in fact the world they are living in hides too many things that can change the course of Riki and Rin's lifes.
Determined to reform the Little Busters, Riki attempts to invite Masato, who refuses, claiming that what only matters to him is to 'become the strongest'. Soon after, Riki and Rin hear news of Masato attacking other students and devise a trap to stop him.
Riki awakens several months before, with no memories about what happened during that time. Riki goes to stop Masato from fighting Kengo, but neither of them listen to him and Kyousuke is nowhere to be found.
While thinking about what Yuiko said to him, Riki is approached by a girl who confesses her feelings for him, but claims that she knows he already likes someone else and flees. Wondering what she meant, Rin's image come to Riki's mind.
The day of June 20 keeps repeating without anyone taking heed of it, except for Riki himself, and no one else seems to find it strange even when it starts snowing. Riki decides to look for Kyousuke to ask for his advice but he is nowhere to be found.
After waking up, Riki learns from Yuiko that she was taking care of him while he was asleep and cannot shake the suspicion that the whole situation has happened with them in the past. Some time later, Kyousuke and the other boys point out that Riki is behaving strangely since his last encounter with Yuiko.
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.
