Genji Ikusabe

Genji Ikusabe (戦部厳至, Ikusabe Genji) has an extreme thirst to fight Homunculi, and is the record-keeper of 'Most Homunculi killed' (332), even more than the number of homunculi killed by Hiwatari and Bravo combined. Ikusabe's powers come from his Buso Renkin, the Jumonji spear Gekisen's recovery ability, his special ability and habit to eat remains of Homunculi he's killed to increase his power and stamina, and the times he can use the recovery ability. Unlike Negoro, Ikusabe cares more about the process of battling then claiming victory, and quit the mission to kill Kazuki when he was defeated by Papillon. In the anime, it is not shown that he eats homunculi, nor does he send Papillon to Kazuki and Gōta. Instead, he falls to the ground after Papillon defeats him.

His Buso Renkin is Kakugane XII, Gekisen (激戦, Gekisen lit."Intense War"), a Jumonji spear (cross-like spear) that can heal any wound of its holder. The spear is even capable of reviving Ikusabe even if Ikusabe's body is blown to pieces. However, Gekisen's flaw is that since it recovers automatically and at a high speed, if something gets caught into where one of Ikusabe's body parts should be, the recovery will fail. If Ikusabe is separated from his spear, then the weapon cannot heal him.Voiced by: Tsuyoshi Koyama
