Early in the morning, Kirihito orders the club members to harvest seaweed and do many other strange things, like standing on an unsteady boat to improve their balance. The club members admire Kirihito's methods, but have doubts about his experience and abilities. They eventually confront him. In order to demonstrate his coaching abilities, Kirihito declares that he will have the rookie Mitsuhashi Kei beat the other club members.

Вот как... Значит, он правда
тренировался эти три года...
