Abeno Haruitsuki

Gyōsei, officially known by his title The Executive, serves as the strict administrative ruler of the Underworld in The Morose Mononokean. Alongside Rippō (The Legislator) and Shihō (Justice), he forms the triumvirate that governs the spiritual realm. Operating from his isolated, locked-down residence known as the Bird Cage, he acts as the rigid, rule-abiding enforcer of the three.
Appearance & Forms
Like the other Underworld executives, Gyōsei can change his physical shape:
• Human Form: He manifests as a very tall, lean man with slicked-back, light hair. He favors formal, structured clothing, typically wearing a long Chinese-style gown layered over a black shirt, tailored pants, and dark gloves.
• True Yōkai Form: His original, terrifying form is that of a colossal black crow. Ominous, spiritual crows often appear in the environment to foreshadow his arrival or serve as extensions of his presence.
Personality & Habits
• Severe Human Aversion: Gyōsei's most defining trait is his deep-seated, intense hatred of humans. He firmly believes that mortals have no right to traverse the Underworld, fearing their presence will cause unrest among yōkai.
• The Ruthless Shut-In: He spends the vast majority of his time completely cooped up inside the Bird Cage. He possesses a cold, merciless disposition and a notoriously sharp, violent temperament when crossed.
• A Suffocating Presence: Gyōsei radiates an incredibly dense spiritual pressure. By simply making physical contact, he can project a suffocating, paralyzing aura capable of bringing even strong spirits or humans to their knees• Hanae Ashiya: Because Hanae is a mortal working inside the Underworld, Gyōsei treats him as an active, dangerous threat to the realm's traditions. He orchestrates elaborate trials, using lower-tier yōkai as pawns to test, trap, or outright eliminate Hanae from the spirit world.
• Haruitsuki Abeno: Gyōsei shares a long, complicated history with Abeno, having served as the young boy's former spiritu

Shihō, widely referred to by his official title Justice, is one of the three elite executives ruling over the Underworld in The Morose Mononokean. He resides in the White Sand Prison, managing the judicial branch and passing judgment on lawbreaking spirits.
Appearance & Forms
Shihō possesses the unique ability to shift between two distinctly contrasting forms:
• Yōkai Form (Beast): A massive, intimidating beast that blends the physical features of a leopard and a tiger. In this state, he sports gold tail rings, unique paw bracelets, and bears the official mark of "Justice".
• Human Form: To contrast his terrifying beast form, he transforms into a young, tired-looking boy. He features short purple hair tied back in a low ponytail and wears a spotted kimono, accompanied by wrist bracelets and leg bandages.
Personality & Habits
• "At His Own Pace": The official series fanbook defines Shihō's core nature with a single phrase: someone who strictly does things at his own pace.
• The Relaxed Mediator: Despite holding a terrifying title and overseeing a prison, he is incredibly laid-back, friendly, and soft-spoken. He is a peaceful vegetarian (a reformed carnivore who loves meat but refrains from eating it). He frequently acts as the rational, calm mediator whenever the Legislator and the Executive descend into explosive, petty arguments.
• Flaws: Because he operates entirely on his own schedule, he can be quite lazy and is known to space out or visibly drool when his appetite gets the better of him

• Goes with the Flow": As explicitly stated in the series fanbook, his defining character trait is simply being someone who goes with the flow. He has a peaceful, exceptionally calm aura, reinforced by a soothing, alluring bass voice.
• The Irresponsible Layabout: Despite holding severe judicial and legislative power, he is famously lazy. Haruitsuki Abeno directly summarizes Rippō as an absolute slacker who loves gambling, heavy drinking, and chain-smoking. He operates his entire branch of government straight from his private house sitting over Newt Lake.
• The Overbearing Big Brother: He is unapologetically obsessed with his younger sister, Shizuku. He dotes on her intensely, constantly trying to manipulate or beg her to come visit him at the lake.
• Hidden Badass: Underneath his smiling, lazy playboy exterior lies an incredibly formidable executive. He quietly, fiercely watches over Abeno and protecting the sanctity of the Mononokean. When the harsh executive Gyōsei unjustly targets Hanae Ashiya, Rippō executes an off-screen retaliation so terrifying it makes Abeno shudder just thinking about it

Rippō, known as the Legislator, is one of the three core executives ruling over the Underworld in The Morose Mononokean. He functions as the lawmaker, dictating the regulations of spirit society and acting as the direct supervisor to the Master of the Mononokean.
Appearance
• Human Form: He appears as a tall, slender man in his late 20s to early 30s. He features vibrant, light blue hair and matching calm blue eyes.
• Attire: His wardrobe features a distinctive color theme of black and deep tones (contrasting with his sister Shizuku's white theme). He is typically seen wearing a dark, greenish-black kimono and haori accented by a contrasting red collar.
• Trademarks: He is almost never seen without a laid-back, perpetual grin on his face and is frequently holding his signature traditional smoking pipe (kiseru).
• True Yōkai Form: While he spends most of his time looking human, his original creature form is a powerful hybrid combining a salamander/newt and a dragon. • Goes with the Flow": As explicitly stated in the series fanbook, his defining character trait is simply being someone who goes with the flow. He has a peaceful, exceptionally calm aura, reinforced by a soothing, alluring bass voice.

Profile & Overview

• The Legislator (Rippō): Shizuku is the younger sister of the Legislator, one of the three powerful rulers of the Underworld.

Key Relationships

• Haruitsuki Abeno: Abeno is a regular customer of the Kiyakudō. Despite her unnerving jokes about his eyes, Kōra treats him as a trusted ally and respects his work as the Master of the Mononokean.
