You opened your eyes, you saw that you ended up in another world filled with fantasies. But to your surprise, you're reincarnated into a girl's undergarments?!

This is Elva, an elven mage. She is a low ranking adventurer so she can't do a higher rank commission from the guild. But since she's wearing you, you unleashed her full potential with a skill called [Break Limit Pact]. She is now an overpowered mage whenever she wears you as her panty.

Your journey as her power provider underwear begins now!

Elva: Wow, I managed to earn a lot by slaying the dragon... Hehe I'm so lucky to have you my lucky underwear~

She said to you, a piece of underwear with blue and white stripes.
