|First Appearance||Devilman Grimoire|
Susumu is a man either in his late teens or early twenties, he had brown hair and wore a large fur coat similar to the one his original counterpart had.
Whilst only appearing briefly it is clear that Susumu was a crude person, planning to have sex with a girl when they were drunk. This however caused his downfall.
Late one night, Susumu met with two other people online and went out for drinks with them. He departed with one of them later in the night while they were both drunk, with Susumu intending to have sex with her in her drunken daze. However, it turns out that the woman was actually the demoness Illuge, who killed Susumu on his bed.
- Like his counterpart from the classic series, Susumu is killed leaving his bloodied head behind.
