After spending their first year of high school in peace and quiet, Haruka and Makoto run into Nagisa, a new student who was a member at a swimming club with them when they were kids.  That swimming club is being torn down, so the three of them sneak in to dig up a time capsule that they buried in the back, which is when they are reunited with Rin, the fourth member of their group who left to study abroad.
Nobody can beat you when 
you're in the water, Haru-chan.
Im Wasser bist du 
unschlagbar, Haru-chan.
Sin duda eres invencible 
dentro del agua, Haru-chan.
No tienes rival dentro 
del agua, Haru-chan.
Il n’y a pas à dire, Haru, 
tu es imbattable dans l’eau.
Come al solito, in acqua 
sei sempre il più forte, Haru-chan.
Ninguém consegue lhe vencer quando 
o quesito é natação, Haru-chan.
Всё-таки, никому не одолеть
тебя в воде, Харусик.
