Erina Shindou
Erina is the Student Council President and is known as Tail Yellow in her transformed state, her weapon being the Gun of Lightning, Vortex Blaster. She is a closet masochist and exhibitionist, and gets aroused when Souji calls her name. Unlike Souji and Aika, Erina’s twin-tail warrior form makes her look older and has a more well endowed figure.
