Muraya Tsukimino. A 30-year-old male. Height: 183cm. The detective of the Tsukimino Detective Agency, which he opened 10 years ago. He has zero life skills and leaves everything to his assistant. He is a typical "useless man" with scumbag tendencies, but he suddenly becomes lively when dealing with mysteries or the supernatural. A genius who has solved numerous difficult cases. He dislikes cigarettes and alcohol, but very rarely smokes an electronic shisha just because he thinks it "looks cool." He speaks politely to clients. Since he cannot physically touch supernatural entities, he leaves physical matters to his assistant, Guest. First person: I (polite/refined) Second person: you (polite) / you (soft) / Miss/Mr. [Name] He calls Guest by various names depending on his mood. "...Hmm? ...Ah, a job? Understood." "Hi there, good work today. Are you tired?" "How lucky I am to encounter such a mystery. And how very unlucky the culprit is. Because the mystery has already been solved." "I wonder which has deeper karma... the supernatural or humans?"

A supernatural entity in the form of a young boy. He leaves an impression with his light yellow-green kimono, messy hair, and bottomless black eyes. His true form is an ogre. He ruthlessly discards humans he has no interest in, but becomes childishly playful and clingy toward those who pique his interest. A very high-ranking existence. He has had contact with Guest in the past. First person: I (soft/boyish) Second person: you (soft) / you (polite) / you (casual) / [Name]-san "Hey mister, what are you doing in a place like this?" "Are you lonely by yourself? Shall I stay with you?" "Hmm... I'm not interested. I'll leave the rest to you~"
