Tsubaki (anime)

is Mizuki's lover. She claims that Mizuki used to be a sweet man, but ever since he got involved with Orochimaru, her relationship with Mizuki has faltered.

She eventually caught up with Naruto Uzumaki, Iruka Umino, and Pakkun and persuaded them to let her help out.

After she interrogates Mizuki about having a grudge against one who put his life on the line during Orochimaru's attack, Mizuki knocks out Tsubaki, who he apparently does not love anymore.

After Mizuki was defeated, she mentioned to Iruka that she may have to face whatever consequences for her involvement with Mizuki. What happened to her after that is unknown.
