Ep. 5: Minato menemukan rahasia Eitarou dan belajar bahwa ketekunan adalah kunci untuk peningkatan.

Rikka Gakuen's juniors emerge victorious in the match against Yamanami, leading Minato to lament his perceived uselessness to the team. Eitarou begins contemplating whether he should quit the team, and he later reveals to Minato that he lied about having been Minato's friend in middle school. In truth, Eitarou always looked up to Minato but was too nervous to talk to him; and he thought that with Minato's memories gone, if he could convince Minato that the two were friends, he would finally have a chance at being friends with—and playing alongside—a gifted water polo player, so long as they no longer played at Shogakukan, where Eitarou reasoned he would never be taken off the bench since there were so many other talented players. Minato visits Akimitsu Bizen, coach of the Shogakukan team, to ask what it was that made him such a good player in middle school. Coach Bizen reveals that contrary to popular belief, what really made Minato exceptional was his perseverance and determination to get better, showcased by his habit of recording and rewatching his practices on DVDs, all of which are still in his room. Relieved at the prospect that sheer willpower and determination—not natural talent—was what made him good before, Minato reasons he can accomplish such a feat again. After revealing this to Eitarou, Minato convinces him not to quit the team. (Source: Wikipedia)
