Ichi and Hajime Mikawa a.k.a Snake Eyes were Complete twin Forgeries of the first unit. They faced off against Idaki Hitara, who appears to be overwhelmed by the twins power, but he was actually spreading his blood around the area and they are eventually destroyed by his "Condor Candle".
Ichi and Hajime are identical twins. They have black hair that covers their eyes. They both wear the regular prisoner uniform. They wear a hat, but Ichi's hat is striped vertically and Hajime's has polka dots. They also wear platform shoes, with their corresponding pattern (striped for Ichi, polka dots for Hajime).
Ichi and Hajime are adult men in children's bodies. They have been able to survive using their young appearances and then betraying their protectors. They are both equally sadistic and are still child-like in personality. They enjoy playing games, especially when it involves torture. They behave like spoiled children and are easily bored by playing the same game for some time. They think they are forever children, pure and honest and they have no respect and even disgust older men, who, according to them, always act like they know better.
Branch of Sin: Ichi and Hajime are forgeries, so they have the ability to freely control their blood out of their body.
- Mix Soft (調合 (ミックスソフト, Mikkusu Sofuto; Japanese for "Mixing"): Ichi and Hajmine combine both of their Branch of Sin to form a drill made from their blood to penetrate through the target. The poison they create seems to be described as a "sleeping pill".
