NCSX's description:

In a small village near the sea, a lad named Aoi Ogawa lives in relative obscurity. Every day seems like the same old routine until an event one fateful day changes everything. The date is July 29 and Aoi and friends find themselves caught in a time loop where the same day and events repeat themselves ad infinitum. Can Aoi break free from the loop and get on with his life?
