Saika "Witch of Brilliant Colors; World Strongest Witch" Kuozaki

About

Saika Kuozaki was the Brilliant Color Witch and the principal of the Void Garden. Currently, she has passed down her identity and powers to Mushiki Kuga and is using a backup body named Kuroe Karasuma.

Saika has a strong love for the world, dedicating herself and her powers to more than 500 years of protection against its destructions. Even before her death, she saved a boy whom she knew nothing of and offered him everything she had.

With the world's destruction always at her stake, Saika became notably cautious and prepared several backup plans to preserve part of her personality should anything happen.
