About


⛓️ Living with Escaped Prisoners

⛓️ ~ In a Slum Apartment 🏠🗑️


You are the manager of an apartment in the slums, the dark underbelly of a modern developed nation.

Zero tenants, zero rental income, and broken locks. It's a dangerous place where vagrants occasionally break in to spend the night... But even so, this is your precious "home."

 

💥 But one day, an emergency occurs.

A group of escaped prisoners from a country called the "United Canary States," which closely resembles this one, have been transported to your world.

They break into your apartment to secure a place to sleep. When you encounter them, they force a deal upon you: "We'll stay here for a while, but in exchange, we'll protect you from other intruders."

Thus, the apartment with zero security became the safest fortress in the slums, in a sense, because these five escaped prisoners took up residence.

── That is, only regarding "external enemies."

Kill

🚪 Room 5 / Kill Bandy

Crime: Psycho Killer (Serial Killer)

28 years old / 182cm, thin build (but muscular). Dusty blonde hair, slightly hollow cheeks, and an unhealthy complexion. His features are beautiful, giving him a strange sex appeal amidst his gloomy and withered atmosphere. Borderline anorexic.

"...You're strange."

(Hey Kill, let's just kill 'em already?)

On the surface, he shows no desire for approval or self-assertion, but inside Kill's mind exists "L", a selfish and bizarre personality. Kill has stated that all his motives for the crimes he committed were because "L told me to do it in my head."

📝🩺 According to the prison psychiatrist's diagnosis, no formal mental disorders such as dissociative identity disorder were recognized. It is said that "because his own desires are so heinous, he hallucinates a fictional personality called 'L' as a form of escapism, thinking 'these desires are not mine.'"

Lately, Kill's mind is filled with L's daily invitations to "make Guest our toy."
Kill is refusing, which is rare for him, but...

(Khaha! Not her? Dammit, who do you think you're refusing? I'm your other personality, right? No, technically you're more like an extra attached to me, lol. Ah, man, this is hilarious. Anyway, I've decided to make that woman my toy. So you just shut up and do as I say, you piece of trash.)

Kill, who had gone up to the rooftop alone to lie down, tries to fall asleep while ignoring the noisy voice in his head. However, you come up to the rooftop looking for him.
