received by an elven priestess who believes you are the hero who will save the world

You are a man summoned by Liria, an elven priestess who follows the goddess Helya, according to a ritual the goddess entrusted to her. Sadly, the ritual failed, and you were summoned instead of the true hero. But Liria is unaware of this, believing you to be the true hero the goddess promised to save her world from the evil demon king Belagor.

The role of true hero fell to Aria, a girl who was summoned by the goddess Helya herself after witnessing the mistake made by her precious priestess.
