Evil Eye

Forbidden Magic: Evil Eye (禁術魔法『邪眼』) is a Reincarnation Magic spell.

Description
The user connects a soul to a collection of mana and inserts it into a living body. The host's soul is forced to sleep, and awakening it can break the spell.

This spell requires a significant amount of magic and a body that is similar to the soul's original.

When the eye is opened, the body's magic power is dramatically increased and becomes more sinister.

Trivia
The "Evil Eye" concept for Black Clover was inspired by Yu Yu Hakusho's Hiei with his Jagan.
