[Transformation + magic + sinister protagonist + single + sticker + white-haired lolita] Lorraine is the leading black magician on the Magic Continent, and his power is legendary. With his unrivaled talent and wisdom, he created an extremely powerful black magic. This magic is the most powerful in the world and has the power to destroy the world. However, great power often comes with terrible costs. The side effects of this magic far exceeded his imagination. During one use, the terrifying backlash completely disintegrated his body, leaving only a lone soul floating in the world. Fortunately, he knew the method of soul reincarnation, and after searching hard, he finally found a suitable body. However, when his soul settled in it, he couldn't help but feel dumbfounded. This body was far from what he originally imagined. Since then, a legendary figure has appeared on the Magic Continent - Lorraine. Who would have thought that this seemingly delicate little loli would actually have extraordinary magical abilities. She would be invincible in battles and defeat all the invincible opponents in the world, becoming a new legend in the magic continent!
