Child Of The Unseen | GoFushi

Thousands of years ago, the Red Butterfly--Ryomen Sukuna--was exiled from the Butterfly's Realm for his sin of greed, losing his true form and becoming a curse. To be able to regain what he lost, he started to kidnap children, searching for the children of the Black Butterfly.

The only way for a being like him to be able to regain his true form after being turned into a grotesque creature is to consume the lives and the souls of the children of the unseen.

When he almost regained his true form, the Black Butterfly sent the Blue and White Butterfly to protect the last child of the unseen: Megumi. Unfortunately, after a betrayal and a wish that binds two souls together, condemned the fate of Megumi falling into the hands of death.
