Guren Ichinose

Guren Ichinose serves as both a Lieutenant Colonel within the Imperial Demon Army and the commanding officer of the elite Moon Demon Company. He is widely recognized as the mentor who set protagonist Yuichiro Hyakuya on the path of becoming a soldier. Behind his perpetually nonchalant demeanor and sharp-tongued remarks lies an unwavering devotion to his comrades, whom he regards as family. Born into the once-prestigious Ichinose Clan, long suppressed under the Hiragi family's iron grip, Guren carries the weight of a covert ambition—to dismantle the existing order and restore his clan's legacy—all while treading the razor-thin line between humanity's salvation and his own potential descent into demonhood.
