Menō is a young girl whose father, Kazua Sakura served as one of Genjuro's lab assistants. Genjuro believed that her hair was of superior quality, making her the perfect candidate for infusion with the Shikigami, a madōgu that controls hair. Her father opposed the plan, but Genjuro uses his madōgu Mugen to shrink him and use him as a hostage to make Menō allow the surgery. After Recca defeats her and rescues her father, she eventually befriends Yanagi and seems to understand Joker. She also seems to have a crush on Recca after he helps her and has Genjuro remove Shikigami.
Menō uses Shikigami (式髪, Hair Animator), an orb that turns strands of hair into weapons by hardening them into needle-like objects. Menō has it implanted inside her body so she can also control the growth and movement of her hair.
- In the Filipino version, her name is Lina Sakura while her father's name changes to Hector Sakura of the anime.
