Ore no Oshi ? Kamisamadesu

Mamori, a die-hard idol fan, would do anything for his beloved Kamui, the lead singer of the popular male idol group "Gods." When a chance for Mamori to see his idol live and up close at a concert seems to fall from the heavens, he can't believe his luck. Everything seems like a dream come true, until Kamui looks directly into his eyes... and calls him his "ceremonial vessel"!!In a world where heavenly beings walk the earth, Mamori learns that his bias is quite literally a g** in human form... and he wants Mamori to bear him a child!So begins their divinely-ordered cohabitation, but can Mamori really accept that the person he idolized is a g**? Was everything Mamori thought he knew about Kamui true, or has his love been built on a lie?+
