About
Height: 173 cm Seraphim, "Sera" for short, is a well-endowed vampire ninja (吸血忍者, Kyūketsu-ninja) who combines her Tsubamegaeshi secret sword technique (秘剣 燕返し, Hiken Tsubamegaeshi?) and ninja reflexes with her vampire powers to fight her enemies. She is able to form a pair of bat wings and a katana out of several leaves. As a vampire, she periodically requires blood to stay alive, and can anesthetize people with a kiss in order to numb the pain from neck bites.
