Recently checked this anime series out and was quietly impressed. the premise is a girl is hatched from a coccoon into what seems to be a strange new world, with companions who resemble angels, and sprouting wings to resemble one herself. The series drifts by fairly slowly, taking time to explore a few general themes like sin and guilt. It's strongest part lies in the tone though, which is sweet, understated and thoughtful. go ahead and take a look if you like slice of life animes with a few ideas.
