Eru Amami

Eru Amami (天海 える) is a newly-transferred second-year high student at Watatsumi High.

Personality
Eru has been fighting as a Knocker-Up long before the story began; as far as combat is concerned, she's an expert, cool and clever. But when it comes to real life, her naivety and lack of life experience really shows.

Etymology

 * Eru's surname Amami means "heaven/heavenly, sky, imperial" (天) (ama) and "sea, ocean" (海) (mi).
