Denji's Father

From the little the series shows of him, he shares his son's hair color and style, and he may have worn a beard or some stubble.

Because he dies before the plot properly begins, his character stays largely obscure, but Makima paints him as an abusive drunk whose violence toward Denji grew so dangerous that the boy killed him to survive. A streak of ruin seems to have run through him as well, since gambling losses to the Yakuza mounted into the enormous debt his son was later forced to shoulder.

As a child, Denji takes his father's life in self-defense during one of the man's drunken rages, fearing for his own safety. The adults around him brand the death a suicide, since calling it a murder would have cut off any payout, and so Denji is saddled with the debt instead. He buries the memory behind a mental barrier pictured as a shut door, recalling only a visit to the grave alongside the Debt Collector, who claimed the man had hanged himself.

The repression breaks open during the Control Devil arc, when Makima, having dug into Denji's past, exposes the killing as his own act and the suicide as a Yakuza fabrication. The revelation forces Denji to picture his younger self once more, looming over the bleeding body of the father he had killed.
