Tsubaki (anime)

is Mizuki's former lover. She claimed that Mizuki used to be a sweet man, but that, ever since he had gotten involved with Orochimaru, her relationship with Mizuki had faltered. After he escaped from prison, she was able to help catch him. After she interrogated Mizuki about having a grudge against someone who had put his life on the line during Orochimaru's attack, Mizuki knocked her unconscious, because he apparently did not love her anymore. After Mizuki was defeated, she mentioned to Iruka that she might have to face consequences for her involvement with Mizuki.
