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.
I'll show you a sight 
you've never seen before.
Ich werde dir etwas zeigen, 
was du noch nie gesehen hast.
Te mostraré una vista que 
nunca antes hayas visto.
te garantizo que te mostraré 
algo que jamás has visto.
Je te montrerai un paysage 
que tu n’as encore jamais vu.
Ti mostrerò un paesaggio 
che non hai mai visto prima.
Eu vou lhe mostrar algo que 
você nunca viu antes.
Я покажу то, чего ты ещё не видел.
