Ryūrei

Ryūrei (流麗, lit. "Fluent, Flowing") is a kunoichi of an unspecified village and nation. Having grown up in the guise of peacetime, she would still aim for the career of a ninja, ultimately becoming anbu. There, she earned the soon to be feared alias of Nukekubi (抜け首, Nukekubi), alternating between the life of a hunter-nin and while steadily accumulating power for herself. Though her exact motives remain elusive, she retains the confidence of her squadron, seemingly content in her current role.
