Genderswapped Demon Lord Can't Win Against the Hero!

The “Strongest demon lord” of another world becomes a “cute girl”!
In a world not our own, there once reigned a Demon Lord who controlled the entire realm. However, in the midst of a battle with a female hero, a magical accident caused him to be transported to modern-day Japan.

And when he came to, the demon lord had turned into a girl! To make matters worse, right after he arrived, he was nearly attacked by humans. With no magic, no physical strength, and utterly powerless…

Absolutely cornered. Just as he thought that—

“Come with me!”

His rescuer turned out to be the female hero. Apparently, she had been transported here along with him. And so, the demon ling found himself under the hero’s care. But what fate awaits him…?
