Shinobu Negoro (根来忍, Negoro Shinobu) is No.5 of the Muto-assassination team, he is an extremely cold character. 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 had Negoro's own blood. He is able to become completely unnoticed in a crowd of people. His Buso Renkin is Kakugane XIV, Secret Trail, a ninjato that can cut open paths to another space that only Negoro, who has the DNA that Secret Trail will recognize, can enter. The sword itself can also be thrown freely the world of Buso Renkin and the special space. Voiced by: Kenji Hamada (Japanese), Yuri Lowenthal (English)
