Yuki

As a creation of Mayu, she represents the dark side of Mayu's personality. Her role was to be the "bad girl", the Girl of Black whose purpose is to spread misery through Selector Battles. In this regard, she holds no malice and isn't truly evil, but a simple existence that plays out the role given by her creator. In her first introduction, she appears to be a quiet, stoic, and cold person. However, this is merely a facade, and like her counterpart, she is very enthusiastic when it comes to Selector battles. She is also callous and feels no remorse for the Selectors whose wishes she had reversed by defeating them. She also likes snow, a personality trait she inherited from Mayu.
