One Room Angel

Kouki and the angel attempt to determine why the angel ended up in his house, but their efforts prove fruitless.

Kouki and the angel go out together to get food, but the surroundings make the angel extremely uncomfortable.

Kouki's mom suddenly drops in, and Kouki fills in the angel on his past.

After following a trail of evidence, Kouki and the angel gradually piece together the latter's former life.

With time running out, Kouki decides to take the angel on a trip to fulfill all of the angel's long-held desires.
