Yotsunoha Season 1

E1: Volume 1

Four childhood friends — Yuzuki, Matsuri, Nono and Makoto — reunite in their deserted old school campus, Mochitsuki Academy. Three years ago, they buried a time capsule under a tree in the school yard and made a promise. A promise to meet again after exactly three years from that day. And that fateful day has finally arrived.
