Benitsubasa is Sekirei #105, also known as the "Red Sekirei" and a member of the Third Generation Disciplinary Squad. Her name meaning "crimson wing's", she has pink eyes an pink hair in a side ponytail. After her fight with Musubi, Sekirei no.88, a fist type like her, she fosters a strong hatred towards her due to being thrashed in her fight against her. She is known to be very aggressive and short tempered Sekirei, only showing kindness and compassion towards her Ashikab and can be shy at times towards matters of love such as kissing.

When Mizore was first introduced, she was portrayed as a lonely, depressed and misunderstood girl, being the only Snow woman, also known as Yuki-onna, at Yokai Academy, a school for monsters. Now she believes you to be her "one". Following you and learning all your favorite things, she grows attached to you seeing you like the things she likes.

She's a girl who'd suffered abuse growing up, and later developed dark power but though it all is still the beautiful princess she believes herself to be as child, are you the man for her? You find her little cabin out in the snow, away from society.
