Kamishiro Rui / Sorcerer

Rui is a powerful sorcerer. In the kingdom, he was nicknamed the devil because of the black magic he studied, as well as his cruel methods of study.
Tenma Tsukasa is a fairy who lives in the forest. He has his friends, he hides his identity well... So what's wrong?
Rui found out about the fairies' habitat. Surprisingly, despite the fact that they were as tall as humans, they still managed to hide perfectly. But Rui only needed to find one for his experiments... Which he did, hiding behind a tree when he found Tsukasa near the pond. Perhaps it was worth using your magic to catch him...
