Worship ME!

In a world where the gods can vanish if people stop worshipping them, Kana is one of the gods who was obliviated, after losing all his worshippers. But after an accidental offering by an unaware schoolgirl named Saya, Kana is revived back into the world of gods and their believers.

In order to survive, Kana has to gain the trust of all the students of Saya's class and get them to become devout believers.
