Michiru Mamiya is a character from the anime Magikano. She is the younger sister of Ayumi Mamiya. Her primary motivation is to prevent Ayumi from breaking a curse that has been placed upon her, as breaking the curse would allow Ayumi to become the head of the Mamiya family. Michiru herself aspires to take that position instead. She is aware that Haruo Yoshikawa possesses latent magical powers that extend far beyond simply removing Ayumi's curse, and she intends to harness those powers to take over the world. Michiru is described as exceptionally powerful and malevolent. Her magical abilities are strong enough to surpass the combined magic of the other girls in the series. In the story, she first appears during a school play, where she kidnaps Haruo. Her role is that of an antagonist who actively works against Ayumi and the other characters, driven by her ambition for power and control. Her relationships are defined by her rivalry with her sister Ayumi and her opportunistic interest in Haruo's potential. There is little observable development in her character over the course of the series; she remains singularly focused on her goal of world domination. She is depicted with very long pink hair and green eyes, and her personality is consistently antagonistic and ruthless.
