Ken Nogami (野神剣 Nogami Ken "Lit"; Hidden God's Blade) was a powerful Master-Class Crimson Sovereign who existed within Akasekai, the home dimension of his brethren. He existed as a member of the prestigious Crimson Sovereign Council, and was regarded as an influential member of his race. After the sealing of the majority of his brethren, Ken became missing in action, and is assumed to be dead, though rumors have been spread that he has been spotted in Rukongai and Hueco Mundo.
