天使の巣箱

"I awoke to a warm, fuzzy feeling.
The sun shining through the curtains caught my eye.
A normal morning in heaven, in the same bed I always sleep in.
But there's something different about me today."

Hisui, a 15-year-old angel, descended from heaven to find a partner to raise an angel's egg with.
In school, his senpais and classmates seem to have ulterior motives,
and he's accompanied by his annoying childhood friend, a kind priest, and even a demon...

Will Hisui be able to raise the egg properly and become a full-fledged angel?
