He is a green crab, with a human-like face. He wears a green jacket with a picture of a crab on the back, as well as green pants and shoes.
He loves to eat crab, and is like a savage, leaving a mess of shells everywhere. He seems to think ultimates would also taste good.
Rukinosu is a living doll, who has the essence of one of the 12 Reverse Zodiac Braves, The CancerAstralArmored BraveCancer. He was summoned by Miroku. Once appearing, he made a mess of crab shells in space, and destroyed the gate to the third class.
He battled against Kiriga, using an ultimate-killer deck, and won easily. Then, he challenged Eris and also defeated her.
Once Kiriga found one of the Tri-Dragon Deities, he fought Rukinosu again. This time, the crab was defeated. Eris also had a rematch with him after she found her Tri-Dragon Deity, and Rukinosu again lost.
After losing in the Justice Cup, Rukinosu was angry. Denebola told him that all he could do was lose now, and Miroku also thought that he wasn't useful anymore.
Later, Miroku summoned a snake which devoured Rukinosu. The CancerAstralArmored BraveCancer card was sent to Miroku's deck, and the symbol for Cancer disappeared.
The Triumvirate pull Rukinosu, Denebola and Miroku out from Nakes' body, during the final battle. Once the battle is over, Rukinosu decides to return to his own dimension.
He uses a green deck, with his Reverse 12 Zodiac Brave as the focus.
