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.
Do not allow an empty 
goblet to face the moon.
Erlaube einem leeren Kelch nicht, auf den Mond gerichtet zu sein.
Nunca dejes que tu copa 
esté vacía bajo la Luna.
Nunca dejes tu copa vacía 
bajo la luz de la luna.
en ayant soin que jamais sa tasse 
ne reste vide en face de la Lune. »
Non permettere a un calice 
vuoto di guardare la luna.
Nunca deixe seu cálice ficar
 vazio à luz do céu noturno.
Пусть полон будет кубок
Под молодой луной.
