Oda reveals unknown information about CP0

Question: “Hello Oda sensei! Starting with Rob Lucci, some CP9 members were promoted to CP0, but does that include Jabra, Fukurou and Kumadori?“

Oda: “If you watched One Piece Film Red you’ll see that Blueno and Kalifa have both appeared as CP0 agents.

Yes, all former CP9 agents were promoted to CP0. But within CP0 there’s a group of people with masks(including Lucci, Kaku, Stussy), they’re called the Masked Assassins and are given more special missions.”
