Tenshi no Subako

"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?
