Gazeru

is an Anbu from Konohagakure.

Appearance
Gazeru is a slender woman with long purple hair that reaches past her back. She wears the typical Konohagakure-Anbu attire, including the tattoo on the right arm and her porcelain mask has a cat-motif with three vertical lines at the top and three on each side for whiskers.

Abilities
As an elite Anbu, Gazeru is a strong kunoichi. With her excellent observational skills, she calmly analyses her enemies. She was also shown wielding a sword, implying skills in kenjutsu.

Pain's Assault
Gazeru guarded the Fifth Hokage during Pain's assault on Konoha. She suggested allowing Pain to leave the village so they can organise a counter-attack only to realise that Pain was not fleeing but preparing a massive attack. She followed Tsunade into the air to try to stop him, but they were promptly blown out of the sky.

Trivia

 * In the anime, Gazeru was replaced by Yūgao Uzuki as Tsunade's guard.
