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.
And the seaweed has something 
to do with it too, doesn't it?
وللطّحالب دور ما أيضًا، صحيح؟
Und mit den Algen hat es
sicher auch was auf sich, oder?
Y también hay un secreto
en las algas, ¿no?
Y también hay un secreto
en las algas, ¿no?
Et ces algues ont sûrement
une utilité cachée !

c'entrano qualcosa, vero?
Esta alga marinha também
esconde algum segredo, né?
А водоросли тоже для чего-то нужны?
