Seraphim

Seraphim, or Sera for short, is a vampire ninja and one of the main female protagonists from the light novel series Is This A Zombie? and the anime of the same name. She is currently living with Ayumu Aikawa, due to wanting to be Eucliwood Hellscythe's servant, although since Ayumu has taken the position, she is now surprisingly Ayumu's servant, however she doesn't act, or like being called his servant at all.

She is voiced by Yoko Hikasa in the Japanese version of the anime and Morgan Garret in the English version.
