Rosuto Shifu

Personality
Her personality to say the least is extremely complicated, as she flips between happy and sad, angry and scared like most people flip coins. She possesses a large inferiority and superiority complex, so if someone was better than her at something, she will obsess until she is better than them, if people are worse than her, she tends to hold it over their heads. She is extremely power hungry, and will do what she needs in order to be able to reach her full potential. This is in part why she left Konoha, as she felt she was being held back by a bunch of weaklings. Her hate stems most from her former graduating class, who despite being kind to her in person, they would always whisper about how weak she was, and that she would amount to nothing at all. Her one goal is to get strong enough to bring Konoha to its knees, and then cut them off at the head. Her anger is strong enough that just the presence of a Konoha shinobi is enough to send her into a range.

Eight Gates
As part of her obsession, she gained basic information on the use of the eight gates, and began to train with a vigor to master as many of the gates as possible. Unlike Might Guy and Lee, when she begins to open the eight gates, her sweat turns pink, surrounding her with a pink aura of sorts. As of now, she is able to open 4-5 of the eight gates, depending on how much chakra she has available and who she is facing, as part of her power seems to be tied to her emotions.
