History
Ever since she was a little girl, Erina had an obsession with heroes and throughout her life, she was always a massive fan that often visited the toy store to buy more super hero toys.

In Episode 1 the Ultimaguil attacked her to steal her twin tail attribute it was at this very moment Soji first transformed from an average 15-year-old boy to the young girl Tail Red by using the "Red Courage" Tail Gear.

She was saved by Tail Red and Erina thanked Tail Red gratefully. It was from this day Tail Red became her idol and she often made speeches about Tail Red at Yogetsu High School.

In Episode 5, Aika became depressed because she was disappointed that while Soji's Tail Gear changed his form drastically turning him into a young girl her Tail Gear had no major effect on her appearance and didnt give her what she wanted most: bigger breasts. Thouars developed the "Yellow Hope" Tail Gear that combined the user's DNA with one that had giant breasts in order to please Aika. But it didn't work for Aika no matter what she tried, because she had bonded with her 'Blue Love' Tail Gear.

By the end of episode 5 Soji was found out to be Tail Red and turns back in front of Erina, he then asks Thouars to give Erina the "Yellow Hope" Tail Gear since she has a Twintail attribute and it will help her to defend herself against the Ultimaguil that would attack her. It works and successfully transforms her whole body into the taller, big breasted, big butted Tail Yellow.
