Leave the Sacrifice at the Gate

Uzumaki Nanao was born to be a sacrifice. However, when his family delivers him to the god who's supposed to eat him, things don't go quite as expected. The god is more interested in taking it easy than sacrificial offerings, totally ruining Nanao's end-of-life trajectory. Can he convince the god to eat him? Or will he learn that there's more than one way to be devoured by a god?
