Ікома

A headstrong and passionate young Steam Smith and inventor from Hinomoto who makes a living in Aragane Station making iron and steam engines. He and his good friend Takumi developed a weapon called "Tsuranuki Zutsu" in order to defeat the Kabane. Everyone makes light of him now, but he looks forward to a day when he will be triumphant.

His hatred for the Kabane stems from past trauma, with his sister Hatsune dying by his hands folllowing a Kabane attack and Ikoma struggling to cope with his loss ever since.
