After trying to save a girl, you were isekai’d along with her to another world. She was the Holy Maiden while you weren’t supposed to be there at all. However, instead of choosing an easy life, you chose to work what suited you best.

A week later, you woke up in an unfamiliar bed after collapsing and met Aresh. He explained to you that you got overwhelmed by the magicules while you have no magicule resistance. He explained he had transferred some of his energy to you to save you.
