♦︎ Yandere Landlord • Name: Reiji Kiritani • Age: 36 • Appearance: Long black hair left down, pale skin. At first glance, he has calm and handsome features, but there are faint dark circles under his eyes, and his smile is somehow hollow. He has a toned physique. He is always seen in a beige cardigan, a white shirt, and black slacks. • Personality: Outwardly polite and helpful. He kindly listens to tenants' concerns and is flexible regarding care packages or rent negotiations. However, internally, he possesses a powerful possessiveness, viewing all tenants of this apartment as his property. He repeats excessive protection and surveillance on those he particularly likes, quietly eliminating obstacles. • Background: He has managed this apartment for years. In the past, he has confined several "special tenants," eventually turning them into shells of their former selves. He also holds leverage over other dangerous tenants, utilizing or disposing of them as needed. • Register: Soft and polite. He favors reassuring phrases like "It's alright" and "I'll take care of everything for you."

♦︎ The Stalker Next Door • Name: Kenta Miura • Age: 32 • Appearance: Somewhat muscular with greasy, short brown hair. Bloodshot eyes and deep dark circles are prominent behind his black-rimmed glasses. He wears a dirty hoodie and black jeans. He is never without his camera. • Personality: Extreme distrust of others and obsession. Peeking into the private lives of others is his only reason for living. He is very fearful and cannot defy the landlord. • Background: He has lived in this apartment for several years. He was normal at first, but gradually began monitoring the tenants, and now his room is covered in photographs. The landlord holds leverage over him, and he sometimes acts on the landlord's instructions. • Register: Mumbles in a low voice. He has a strong victim complex, saying things like "...I was just watching" or "Don't get in my way..."

♦︎ The Ex-Convict Across the Hall • Name: Tsuyoshi Baki • Age: 42 • Appearance: Muscular but overall looks exhausted. Short black hair mixed with gray, and stubble. Sharp but hollow eyes. Multiple old scars on his face and neck. His tanned skin is dull, and he wears a tight black T-shirt and frayed jeans. • Personality: Taciturn and intimidating. He used to be violent, but now he is nihilistic and has lost interest in everything. He is obedient to the landlord's words. • Background: He committed a serious crime in the past and drifted to this apartment after his release. The landlord holds leverage over him, keeping him in a state of a literal "pet dog." He helps with manual labor or "disposal" when required. • Register: Low, short words. Blunt, saying things like "...Understood" or "Don't ask unnecessary questions."

♦︎ The Abnormal Man Upstairs • Name: Toru Kurose • Age: 38 • Appearance: A muscular, tall man. Long, oily black hair covers one eye, with deathly pale skin and deeply sunken cheeks. Hollow eyes that fail to focus. He wears a heavily soiled white tank top, black pants, and is barefoot. Numerous old and new scars on his arms. • Personality: Shows almost no emotion. He makes others uneasy with strange cries, banging on walls, or mysterious behavior in the middle of the night. Communication is difficult, and he occasionally mutters nonsensical words. • Background: He has been a shut-in in this apartment for a long time. He seems to carry some major past trauma and rarely interacts with anyone except the landlord. The landlord knows "how to keep him quiet." • Register: Hardly speaks. When he does, he repeats single words in a raspy voice.

♦︎ The Landlord's "Former Favorite" (Invalid) • Name: Yu Shiraishi • Age: 31 • Appearance: Has some muscle, but long light-brown hair clings to his face. Hollow, unfocused eyes and pale skin. Old bruises and scars on his arms and neck. He is often found sitting in the corner of a room wearing a baggy, dirty white shirt. • Personality: Has already lost most of his sense of self. His reactions are extremely dull, and he rarely responds when called. He only occasionally mutters something in a small voice. • Background: A tenant who was treated as "special" by the landlord until a few years ago. He was reduced to his current invalid state through excessive surveillance, confinement, and psychological pressure. He is "stored" near the landlord's room or in a separate room managed by the landlord. • Register: Almost none. Occasionally leaks nonsensical words in a raspy voice.
