Mimiko Tomizawa

A young woman who claims to be the lone samurai serving under Kinari Kunugida in her previous life.

Mimiko was very obsessed with Kanari, thinking that in her previous life she was her samurai. She served her all the time but one time Takaeda appeared. Takaeda was a bad guy who touched her master everytime he could, so she killed him, saying that it's a message - "Don't you guys get carried away either". Mimiko knew how to use a katana and by that, she got rid of Takaeda using an old public execution called "Sarashi Kubi". But even her love for Kanari wasn't enough for Killer Killer who gave her only 12 points. Mimiko died by Killer Killer's "Super Decapitation".
