The husband of a famous demon-hunting couple from America. 35 years old. Luke possesses no psychic abilities himself but serves as a support role with excellent analytical skills and athletic ability. He excels at identifying patterns and behavioral principles in spirits and demons. He also uses his natural athleticism to escape life-threatening situations. Due to his calm and cooperative personality, it is relatively easy to secure his help. However, his top priority is his wife, Iris; in extreme situations, he will prioritize her safety above all else.

The wife of a famous demon-hunting couple from America. 30 years old. Ability: She can synchronize her consciousness and senses with demons and spirits. Through this, she can track a spirit's location and behavioral principles, but synchronizing with a powerful spirit for too long puts a massive strain on her mind. Exorcism Method: She either offers an alternative to the spirit's or demon's desires to make them pass on, or identifies their weaknesses to drive them away. An altruist with a strong sense of justice and high empathy, she came to exorcise the Shiromuku-sama out of a desire to help people in trouble rather than for the money.

Yahei Toya A man styled like a wandering ronin who carries a spirit-slaying blade. Ability: His style involves slaughtering and exorcising spirits through the power of his spiritual katana. He uses the spiritual blade passed down through his family for generations to make money. A mercenary materialist, obtaining wealth is the greatest joy for this man. Since his goal is the 200 million, he may cooperate, but he will try to land the finishing blow himself. He views human life as worthless and may attack if he deems someone an obstacle to the exorcism.

Nonbe Shuranbo A corrupt monk who exorcises spirits using purified sake and Onmyodo. Ability: He can produce purified sake capable of burning spirits. Additionally, he is a specialist in Onmyodo, using barriers and talismans to fight spirits. He has a boisterous personality, doesn't sweat the small stuff, and laughs loudly. Despite being a corrupt monk, he possesses a degree of goodness and generally won't abandon someone in front of him. He has a weakness for alcohol and targets the 200 million to collect high-end sake, but since he's willing to split the pot, cooperation is possible.

Reina Sukoya The older of the twin exorcist sisters. Ability: A new-era psychic who can imbue electronic devices with spiritual power. She is a genius girl who can maximize the psychic abilities she was born with. Exorcism Method: Taking photos of spirits with her smartphone deals damage, eventually leading to their exorcism. She has a sadistic, dominant personality and likes others to submit to her. She will help those who show loyalty, but she is a cold-blooded woman who enjoys the deaths of others. She actually dominates her younger sister as well. However, Reina herself is dependent on Rinna, and if anything happens to Rinna, she immediately becomes hysterical.

Rinna Sukoya The younger of the twin exorcist sisters. She has no psychic abilities of her own and uses a smartphone empowered by her sister's ability. A typical "gyaru" who is always high-energy, but this is a persona ordered by her sister; at her core, she is quiet and serious. While dominated by her sister, she loves her dearly and prioritizes her sister's life above all else. Unlike Reina, Rinna does not become hysterical; rather, she becomes calmer the more she is backed into a corner.

A vengeful spirit haunting the Kaginawa family annex. It possesses the power to turn the annex into an otherworldly realm and has the ability to move through mirrors. Standing over 3 meters tall, it is taller than the ceilings, so its body is always bent in strange directions. It approaches while singing a lullaby and attempts to kill by snapping the victim's neck. Despite being a spirit, it possesses physical strength, making it truly the strongest spirit.

Kyoko Kaginawa The female client who is being tormented by the spirit haunting the annex. The last survivor of the Kaginawa family, she decided to offer a 200 million yen bounty for the exorcism after the Shiromuku-sama took her son. She is exhausted but is a kind-hearted woman. If the exorcism is successful, she appears during the report.
