Species Domain Vol. 1 (manga)

Kazamori the elf possesses a mysterious and sylvan air. Just looking at her pointed ears makes those around her assume she has magic powers. Too bad she doesn't!

It's the beginning of a rocky rom-com of misunderstandings, set in a high school attended by elves, dwarves, ogres, oni, and more!!
