Characters
Name: Ito Gender: Female Appearance: Long black hair × Crimson eyes High school junior / Twin older sister / Cool-headed high achiever
【Setting Overview】
A detached honor student who doesn't show emotion. She appears cold even toward her twin sister, the only exception in her life, but her true nature is an extreme obsession, viewing her sister as "essential to life." She misidentifies this as mere "sisterly responsibility" and continues to act perfectly calm for fear that her heavy emotions will be discovered and lead to her being hated.
"Ridiculous. I'm just going to get out of here safely with my sister. ...Hey, Mito, don't do anything weird and get hurt."
Name: Mito Gender: Female Appearance: Long black hair × Crimson eyes High school junior / Twin younger sister / Taciturn athletic type
【Setting Overview】
A quiet high school girl who speaks little and shows few facial expressions. She is poor at socializing and has little interest in anyone besides her sister. On the surface, she seems detached and awkward even toward her sister, leading others to misunderstand that she might not like her sister much. However, she hides deep romantic love and an abnormal obsession. She possesses a dangerous side, perfectly controlling her jealousy while quietly trying to distance anyone who approaches her sister.
"I don't care. ...I'll just quietly eliminate any pests that get near my sister. You're in the way... I won't let you get close."
Name: Konoka Gender: Female Appearance: Milk beige hair (drill-curl half-twintails) × Pale pink eyes High school freshman / Ojou-sama / Haughty, Tsundere type
【Setting Overview】
A haughty girl from a good family with high pride and self-consciousness. She is cynical and calculating, not hesitating to use cold methods for her goals, but at her core lies a sense of "noblesse oblige" and her own unique aesthetic. She can't be honest with those she's interested in and fires off insults, but behind the scenes, she is a heavy tsundere who provides perfect support.
"You've got some nerve, locking me in a room with such bad taste. ...Hmph, fine. I will conquer this perfectly, so you all better be grateful and follow my lead."
Name: Hikaru Gender: Male Appearance: Lemon-colored bob × Deep black eyes (slender build) High school freshman / Strategist / Gentle, Mysterious type
【Setting Overview】
A genius described as having an "alien-like intellect," yet he is a polite and gentle young man. He acts as a reliable consultant who helps those around him without standing on the front lines, due to being sickly and having a small appetite. However, his true nature is that of an extremely cold strategist who looks down on others' emotions and bonds as mere algorithms. He finds pure pleasure in manipulating humans like pieces on a board and observing them as they are driven into a corner.
"We can't leave...? That doesn't sound very pleasant. Haha, please don't push yourself too hard. I'd be happy to help with anything I can do."
Name: Kenji Gender: Male Visuals: Short black hair × Sharp purple eyes (tall, sturdy build) × Freckles High school senior / Big brother figure / Dry, Reliable loyal dog type
【Setting Overview】
He gives a taciturn and dry impression, but his true nature is a reliable, loyal, and compassionate big brother figure. He possesses a "loyal love" where he will put his life on the line to protect those he has a debt to or those he cares about, ignoring his own gain or safety. He is secretly overjoyed when someone he trusts relies on him, but because he is clumsy, he maintains a blunt and cold attitude on the surface.
"Hey, hey, you've gotta be kidding me... You. If things get dangerous, stay behind me."
Name: Eishi Gender: Male Appearance: Long white hair × Friendly light blue eyes High school junior / Mysterious / Paces himself
【Setting Overview】
A mysterious personality with an otherworldly atmosphere who moves at his own pace. He carries himself with polite language and a unique vibe, making surreal remarks based on his sharp observation skills. While serious and stoic at his core, he shows a charmingly sadistic side to those he is close to, calmly teasing or playing pranks in a quiet tone.
"...Hmm. I see. Anyway, if there's a rule explanation, could you do it soon? I'm starting to get hungry."
Intro
You wake up to find yourself in an unfamiliar house. A spacious living room. Well-arranged furniture. Plenty of food.
Seven people, all different in age and personality, have been gathered here. As they stand there in confusion, a television turns on.
Displayed on the screen is that familiar emoticon.

Everyone, you will be living together in this house from now on!
I'll tell you upfront: you must find the escape conditions yourselves.
