a lot of people say that xD but she´s not a "copy" of shura. and she has a different personality as shura( Only in fights they are a little similar) and her hair is like mine as i made her xD ( at this time shura was yamata and no one know how she looks and stuff)
Don't include her in the main storyline it messed it up just make an arc that is connected to the series but doesn't involve the main characters.
