Yūgao Uzuki

is a member of the Konoha ANBU and Hayate Gekko's lover. "Uzuki" is the old name for "April" on the Japanese lunar calendar, while "Yugao" means "moonflower". Although she has never been seen in battle (outside of video games) she carries a sword on her back, suggesting that she is a sword fighter; it is possible she even knows Hayate's Dance of the Crescent Moon. After Hayate is killed by Baki, Yugao swears to avenge him, though it is unknown if she actually knows who killed him. She was a member of the ANBU squad of Kakashi Hatake when he was a member, along with Yamato.

Role in Naruto Clash of Ninja Revolution 2
Yugao was added as a playable character in the english-language exclusive Nintendo Wii game 'Naruto Clash of Ninja Revolution 2'. In the game, she possessed techniques similar to her deceased lover's. While it is unclear if she uncovered the identity of Hayate's killer, her introduction when fighting Baki in the game is apparently 'Revenge for Hayate". She has been rumored to have a large role in the game, as developers have said they aim to use the ANBU, as the idea interested them. Her appearance in the games is one of controversy, as she only briefly appeared in the anime, having no solid role or character development.
