No.5 of the Muto-assassination team. Almost always hidden inside his own 'space' created by his Buso Renkin, the Secret Trail. His clothes and his hair are sewn into it as well. The opposite of Ikusabe, he cares about claiming victory more than the process of beating his enemies. He was later defeated by Gōta when he hid in his own space after being ambushed by Gōta's motor gear, only to have the two chakrams hit him again as both chakrams have Negoro's own blood. He is able to become completely unnoticed in a crowd of people.
