Little Busters! Refrain

Proof of the Strongest

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 classmates and comes with a trap to catch him. However, the trap fails to restrain him fully and he starts pursuing them, after setting another trap with Rin's help, Riki manages to wear down Masato to the point of being able to defeat him barehanded. The knocked down Masato then reminisces that before meeting Kyousuke, he used to be treated as a fool by his peers until he trained his body enough to beat down whoever insulted him, but became isolated because of it, until Kyousuke appears and defeats him also using traps, leading to them becoming friends. It is also revealed that the reason for his rampage at school was because he suddenly started seeing everyone else as himself and believed that he could only become his own person by becoming the strongest of them all. After renewing his friendhip with Masato, Riki realizes that he must eventually defeat Kyousuke as well for his and his friends' sake, while a serious Kengo watches over him from afar.
