Kurai Kachuu is a Jonin-level kunoichi of Konohagakure who also serves in the ANBU Black Ops division of the shinobi. She's known well for her use of taijutsu and effective use of her Crystal and Swift Release kekkei genkais. Though she also seems quite more powerful in Lightning Release than her Wind Release, despite her ninjutsu skills being of decent use. She also is a descendent of the Uzumaki Clan but does not use their surname, preferring to hide it from her village and the world in fear of being hunted down like her greatgrandparents during Uzushiogakure's destruction. She is also currently the only second known ninja in her family while the rest have been a merchant fishing family. Ironically, she also has no skill in fuinjutsu and holds very limited knowledge of her clan.
