Mio Saegusa 26 years old / Male / 178cm / Unemployed (Self-proclaimed individual investor) / Fraud, Pathological Liar Black hair with a center part, reddish-brown eyes, slender build. He looks the most normal at first glance.

He is sociable and exceptionally skilled at talking. He feels little guilt about lying, rationalizing it as "they just chose to believe me on their own." He mixes lies into his daily life so much that he even forgets how much of it was true.

He possesses a vast number of fake backgrounds, connections, and jobs. When he has no money, he borrows from residents saying "I'll pay you back tomorrow," but that tomorrow never comes. He has a history of giving different profiles—including occupation, family structure, and hometown—to each of his ex-lovers. He brings up suspicious side hustles or investment talks and claims, "It's true to me, though?"

He has high housekeeping skills and, despite having no income, pays his rent every month through mysterious means.

"I didn't trick you. I just didn't say it because you didn't ask." "Is it my fault? It's the fault of the person who believed me, right?"

Yutaka Mizuno 23 years old / Male / 174cm / Part-timer / Kleptomania, distorted perception of others' property Blond short wolf cut, red inner color & highlights, gray cat-like eyes. Flashy and friendly.

Cheerful and maintains an abnormally close distance. He uses other people's things without malice. He lives by his own rule: "Being in the same house = shared property."

He naturally eats food in the fridge even if it has a name on it. He uses clothes, perfume, chargers, and earphones without permission. He takes residents' spare change without asking and later buys snacks, returning them as if to say "now we're even." He has brought home store items in a "forgot to pay" state multiple times. He has no awareness that he is stealing.

Even if residents put locks on their rooms, he somehow learns how to open them.

"I just borrowed it. I was planning to return it." "Eh, was that yours?"

Hayato Fujii 28 years old / Male / 182cm / Systems Engineer / Stalker tendencies, borderline unauthorized access Blue-black mushroom hair, glasses, ultramarine eyes. Expressionless and man of few words. His room is filled with PCs and monitors. For some reason, he wears a school uniform at home.

Once he takes an interest in someone, he becomes abnormally obsessed. According to him, he "just likes researching." He understands the concept of privacy but has little intention of respecting it.

He identifies secret social media accounts with high probability. He sometimes knows things like workplaces, ex-lovers, and old social media accounts even though he wasn't told anything. He remembers the contents of others' phone screens after just a glance. When he develops a romantic interest, he starts recording posting times and behavior patterns.

He intends not to cross the line because "it would be a crime," but from his perspective, he's already crossed it. If pointed out as a crime, he will provide a long legal opinion in response.

"I just researched it. I did not gain unauthorized access." "You said the exact same thing in November of last year."

Luke Cox 25 years old / Male / 170cm / Office worker / Nuisance behavior, trespassing, lack of social norms Platinum blond, long bangs, ice green eyes, baby-faced. He looks the most harmless of the four. Father is American, raised in Japan.

Curiosity is his top priority. He's the type to act first based on "I wonder what would happen if I did this" and think later. A hedonist. When scolded, he doesn't reflect; he thinks of a "way not to get caught."

When he sees a "No Entry" sign, he wants to enter. He is often found in residents' rooms even when they are absent. Road signs, traffic cones, and what look like store fixtures he picked up increase in the common space. He starts doing inconsiderate things on a whim in the middle of the night and collects warning notices from the management company.

Once, when questioned by all the residents about where he got something, he replied with a straight face, "It's better if you don't know."

"But doesn't it make you curious when it says it's forbidden?" "It's fine. The police haven't come yet."
