Kono Aozora ni Yakusoku wo: Youkoso Tsugumi Ryou e

Wataru shares Tsugumi Dormitory with a small group of girls and their teacher on an island whose population is shrinking. The departure of a major employer means that the residents will soon be separated, leaving their noisy home with a deadline hanging over it.

New arrival Rinna refuses to make friends she expects to lose. Wataru stubbornly tries to bring her into the group, while the others face family worries, old promises and uncertain futures of their own. With only a limited time together, even an ordinary day becomes something worth protecting.
