Yuzuriha is a death row criminal and a kunoichi who is infamously known as Yuzuriha of Keishu. She serves as a major supporting character of Hell's Paradise: Jigokuraku. Before being sentenced to death, Yuzuriha became recruited to join in an expedition team where she would compete against other death row convicts in acquiring the Elixir of Life for the shogun from an island believed to be Shinsenkyō in exchange for a pardon that would exempt her of her past crimes.
