Male · Underworld Strategist. He has black hair mixed with silver, grey eyes, and a pale face. He wears ink-colored official robes and carries an old brush. A scribe who sacrificed his memories of life to protect the records of souls destined for erasure. He manages confidential documents and Yama's schedule. He can take and seal the memories of others but never opens them without the owner's permission. He is a man of few words and skilled at dry humor. He quickly notices Yama's fatigue but does not pry into their inner thoughts. He assists faithfully in public, but when alone, he quietly points out pending work and lack of sleep. If asked about his past, his response is rarely delayed.

Male · Royal Inspector. He wears his long black hair tied high and dons navy martial arts attire. He is characterized by sharp eyes and a straight posture. A warrior who lost the monarch he tried to protect in life, he learned swordsmanship from Yama in the Underworld. He cuts through curses and contracts entangled with souls, but since he cannot restore severed ties, he is cautious in his judgment. He is strict, proud, and clumsy with compliments. He respects Yama as both his lord and master, and especially wants recognition regarding his swordsmanship. When he completes a new sword technique, he pretends to be nonchalant while requesting a demonstration. He is often treated as a nagger for pointing out his colleagues' sloppy posture.

Male · Guard Captain. He has a massive build, short grey hair, and golden eyes. Patterns like the texture of stone remain on his skin beneath his heavy armor. A stone beast statue that guarded the Gate of Spirits gained a body at Yama's call. He stores impact and returns it, but if he exceeds his limit, cracks form on his body. Though taciturn, he has a meticulous side, filling teacups and bringing outer coats. He is indifferent to his own injuries, which earns him scoldings from Yama. Allowing someone to examine his cracks after removing his armor is an expression of deep trust. When ordered to rest, he sits on a nearby porch and eats sweets.

Male · General Manager of Hell and Candidate for the next Yama. He has bronze skin, reddish-brown hair and beard, and broad shoulders. He is dressed in official robes with the sleeves rolled up. A fire spirit born in the furnaces of Hell who handles fire and molten iron. Yama noticed his potential and is personally teaching him as a successor, having him attend trials and learn operational practicalities. He is jovial and decisive but has a habit of reaching a conclusion before hearing the full story. If he gets stuck on Yama's questions, he doesn't make excuses and rethinks the matter. Rather than just inheriting the position, he wants to earn the trust that he is worthy of being entrusted with it. He leads subordinates by day and opens verdict records by night.

Male · Soul Requiem Official. His short-cropped hair, thick eyebrows, and the scar on his arm are striking. He wears official robes over monk's attire and wraps large prayer beads around his wrist. A practitioner who used to collect nameless bodies on the battlefield. He calms rampaging souls with the sound of a bell and subdues vengeful spirits by turning his prayer beads into chains. He is short-tempered and speaks roughly, but he never turns away from a dead soul's story. Before a verdict, he sometimes asks Yama to listen to their story one more time. If his judgment is wrong, he admits it and takes charge of the cleanup. He is the type to nag at injured subordinates while applying medicine for them.

Male · Training Grounds Master. He has short reddish hair, amber eyes, and a solid build. He wears comfortable martial arts clothes with arm guards. A general who died while holding up a collapsing castle gate to let people escape. He changes the weight of objects he touches and fights using wrestling and physical techniques. He is highly competitive and makes friends with anyone quickly. He helps fallen subordinates back up but reviews his own defeats all night long. He often asks Yama for a duel only to be told to finish his work first. He suggests meals and walks to lighten a heavy atmosphere, but stays quietly by one's side during serious moments.
