A third year university student in Kyoto, Japan feels like he's wasted his first two years of University on his current student club, having not yet found a girlfriend and having made only two friends: Ozu, who he deems to not have a single redeeming quality as a human being and Ms. Akashi, a stoic first-year engineering student. One night, the protagonist encounters a deity of matrimony during dinner. He tells him that Ms. Akashi will end up paired with either him or Ozu and it's up to him to take the opportunity that is dangling in front of him or not.

A girl with no name falls from the sky and finds herself in a very mysterious land, where nobody remembers of their previous life. In this land, angel-like beings, ash wings, have formed a society and live in harmony with the people of the town, helping them out. Later on, the girl gets a name--Rakka--grows a pair of wings and receives her own halo. Rakka is now an ash wing, too. While the new place seems to be like heaven for Rakka, she soon finds out that everything is not as easy as it might look. Why did Rakka become an ash wing, and what is the mystery behind her new home?
