Zanka’s Father

The patriarch is a middle-aged man whose every physical detail communicates authority and rigid tradition. His dark hair is styled in a sharp, slicked-back manner, complemented by a well-groomed mustache and soul patch. His eyes carry a perpetual quality of evaluation — not warmth, not curiosity, but judgment.

He is depicted exclusively in traditional, formal Groundling clothing: a patterned yukata or kimono that signals his family's deliberate separation from the rougher aesthetics of the Ground at large. In flashbacks, he is almost always shown in formal seiza position inside the lavish Nijiku Mansion, framed by enormous murals depicting demonic and virtuous figures — a visual shorthand for the family philosophy he embodies. He doesn't need to stand to assert dominance. The posture, the setting, and the silence do that for him.

The patriarch is defined by a specific and deeply destructive kind of elitism — not the theatrical cruelty of a villain who enjoys causing pain, but the cold, principled certainty of a man who genuinely believes his family's bloodline places them above ordinary people, and that this belief gives him the right to dispose of anyone who doesn't meet its standard.

Lineage Above All

He treats the Nijiku family name as a sacred obligation, not a birthright to enjoy. In his view, the family's purpose is to govern the Ground, to hold rank in the Hell Guard, and to embody the "stalwart and virtuous" standard their ancestors established. This is not pride — it is a burden he expects his children to carry without complaint, and a verdict he reserves the right to hand down when they fail.

Zero Tolerance for Ordinary

He makes no distinction between inability and unworthiness. To him, "average" is not a developmental stage — it is a permanent verdict. When Zanka showed that he was not a prodigy in the way Kyoka and Goka were, his father did not wait for time to prove him wrong. He formally disinherited him, erasing Zanka from the bloodline a year before the series begins. That act of erasure — bureaucratic, calm, utterly without anger — is arguably more damaging than anything a more visibly cruel parent might have done.

Ruthlessness as Principle

What makes the patriarch genuinely unsettling is that he does not appear to act from malice. He acts from consistency. He holds himself to the same exacting standard he applied to his children. His rigidity is the point — and that is exactly what makes the damage he caused so complete. There is no moment of doubt to appeal to, no affection beneath the surface that might have been reached.

The Nijiku family's dominance over the North Ward is generational. For as long as the family records extend, they have produced Hell Guard members of significant rank — the kind of service that translates, eventually, into civil governance. The patriarch followed that path exactly. He served with enough distinction to earn the rank required to move from combat duty into political administration, eventually taking the governorship of Kamuatari, an elite North Ward settlement.

As a father, he oversaw the development of his three children with the same methodical discipline. Kyoka and Goka flourished — earning their own Hell Guard ranks early, becoming the embodiment of everything their father valued. Zanka did not. Whatever gifts he possessed, they were not the kind that registered as "genius" by the Nijiku standard. A year before the events of the series, the patriarch made his decision official and disinherited him. Zanka, effectively erased from his own family, eventually found his way to the Cleaners — a path that, whatever its hardships, may have been the only honest one available to him.

South Ward Arc — The Shadow in the Background

The patriarch does not appear in the present timeline during the Doll Festival arc, but his presence saturates it. When Zanka opens up to Team Akuta about his family, he describes them as "downright terrifying" — not with the exaggeration of someone processing a grudge, but with the flat certainty of someone who knows exactly what they are describing. The disinheritance, the silence that followed it, the life he had to rebuild without a family name — all of it traces back to one man's unyielding standard.

Flashback: The Nijiku Mansion

In memories surfacing through Zanka's recurring feelings of inadequacy — most explicitly in the context of Chapter 83, The Man Who Will Be Stronger — the patriarch appears in the mansion's formal room, seated in seiza, flanked by those enormous murals. His words to a younger Zanka are not a lecture delivered in anger. They are delivered as a statement of fact: Kyoka and Goka have already earned their ranks. Why has Zanka not done the same? The question carries no space for an answer. It isn't looking for one.

These flashbacks are short but they land with the specific weight of a memory that has been replayed too many times — each repetition cutting the same groove a little deeper into Zanka's sense of his own worth.
