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)(https://anilist.co/character/88073/Satomi-Koutarou) after he saves her life and eventually leaves Darkness Rainbow to join his group and eventually his band of knights as treasurer.]
