The Bloody Twins (ツインズ, Tsuinzu), Jiji and Djidji, are a pair of brutal serial killers that are loyal to Birds. As such, they are part of the Kokuyo Junior High Gang. They were first seen in the Kokuyo Arc where they were used to blackmail Tsuna, Gokudera, Bianchi, and Yamamoto; however, they were then defeated by Shamal's Trident Mosquito and Future I-Pin's Daisangen. They use their sharp fingernails to attack and they are very effective weapons as they can easily slice through hard objects.
AppearanceEditThey have grey skin and wear green Kokuyo suits. They are tall and skinny. Their faces look mutated because of the long term restraints they were placed on in the Vendicare Prison. They have distorted movements that include squirming around and waving their arms. They have long fingernails that are used to lacerate and scratch.
Jiji and Djidji were serving out a sentence in the Vendicare Prison when they escaped with the others in Mukuro's gang. They went with him to Japan in search of Tsuna so that Mukuro could possess him and destroy the Mafia, a stepping stone for their plan to eventually destroy the world.
Before Birds engaged Tsuna and his group, Jiji sought out and shadowed Haru while Djidji sought out and followed Kyoko.
Once Birds gave them the orders to kill Haru and Kyoko, Didi was impeded by Shamal, who allowed Kyoko to get away. Before Djidji could fight Shamal, the Vibration Syndrome he had been infected with surfaced and incapacitated him. Jiji tried to kill Haru, but he was stopped by Future I-Pin, Haru being led away by Future Lambo. Before Jiji could pursue them, he was defeated by Future I-Pin's Haisangen maneuver. It is unknown what happened to them afterwards.
- Like everyone else, Jiji and Djidji wore Kokuyo uniforms because, according to M.M., it "amused Mukuro."
- It was revealed in the fanbook Vongola 77 that the Bloody Twins are the fifth creepiest mafioso in the world in Fuuta's ranking book.
- The Bloody Twins' home country is America.
