Maki Aika

Maki Aika is a magical girl, much like Yurika. However, she is part of "Darkness Rainbow", an extremist organisation whose motives are as of yet unknown. She is Yurika's rival/arch-nemesis.

~!She later befriends Koutarou Satomi after he saves her life and eventually leaves Darkness Rainbow to join his group and eventually his band of knights as treasurer.!~
