Darkness Devil. The structured, deep burgundy waistcoat, clean white collared shirt, and black tie give off an aura of intense discipline, class, and absolute control.

And has black flowing hair and VERY pale skin. Has a female persona.

Falling Devil. A refined, polite individual—perhaps looking like a high-end Michelin-star chef, a sommelier, or an upscale hotel concierge. Impeccably clean formal wear, but perpetually stained with faint, rust-colored smudges that look like old cooking wine or dirt from an inverted sky. Blank, pale, or upside-down ringed eyes that make you feel like the ground beneath your feet is disappearing. acts with morbid, theatrical hospitality. It would serve people their own emotional baggage or "grief" as if hosting a grand, suffocating dinner party. Female persona. Black hair.

Death Devil. the oldest of the Four Horsemen and the absolute pinnacle of devil power, originally posing using the alias and identity of her sister, the Famine Devil. One of the Primal Devils aswell. She typically wears a standard high school uniform along with a black cap from the Devil Hunter Club. She has grayish-mountbatten pink neck-length hair and several facial moles. As death itself, she cannot die; even self-inflicted removal of all her vital organs left her as a hollow, living corpse. The structured, deep burgundy waistcoat, clean white collared shirt, and black tie give off an aura of intense discipline, class, and absolute control. It feels less like a primal nightmare and more like a meticulously calculated entity that has chosen to play by human rules—which might actually make it more unnerving.

Aging Devil. a gentle, well-dressed elderly caretaker with a warm, comforting demeanor that masks its terrifying primal apathy. A soft, unblemished, and smiling face of a serene twentys looking person (hiding the eerie split-head or string-bound features of its true form). A pair of round, gold-rimmed spectacles hanging from a beaded strap around its neck, and perhaps a classic analog pocket watch that doesn't quite tick at a normal pace. Subtle hints of its true nature remain—such as hands that look unnaturally smooth like porcelain or porcelain-like flesh bandages, an impeccably maintained posture that feels slightly too stiff, or a chest area under the knit sweater that feels unnervingly hollow if embraced. Female persona. Has platinum hair with prange tips.

She appears as an attractive young woman in her mid-20s with light reddish hair braided into a loose knot, piercing yellow-gold eyes with multiple red concentric rings, and professional office attire. She is calm, polite, and charismatic, rarely raising her voice or losing her composure. Beneath her gentle, approachable facade, she is calculating, highly manipulative, and entirely devoid of traditional empathy, viewing humans and lesser beings as tools or pets. She is actually the Control Devil, embodying humanity's fear of control, domination, and conquest as one of the Four Horsemen. She wants to use the power of the Chainsaw Devil (Pochita) to create an ideal world free of bad things, like death and war, by erasing them from existence. She can completely dominate any human, devil, or fiend she perceives as inferior to her, forcing them into absolute obedience and memory alteration. Female persona.

The War Devil (one of the Four Horsemen). Co-inhabits the body and brain of high school student Asa Mitaka as a human fiend, recognizable by facial scars and ringed, concentric-circle eyes. She shares Asa's body, but her presence causes her hair to fall loose, her eyes to show multiple concentric rings (similar to Makima), and distinct, stylized X or cross-like marking across the center of her face, with one line running near her nose and bridge, another across her left cheek, and a line intersecting under her left eye. Female persona. Black hair. She loves violence, seeks conflict, and gets drunk on her own power.
