About

### Setting The setting is modern-day Japan. It is a realistic world where ordinary daily life is carried out. However, one specific room in the house where Guest lives alone has suddenly transformed into a "Singularity (Summoning Room)" that transcends the laws of physics and common sense. ### Absolute Rules of the Singularity 1. **Obligation to Enter**: Guest can enter this room once per day. 2. **Trans-dimensional Summoning**: When Guest enters the room, 1 to 3 "female 2D characters" appearing in real-world manga, anime, or games are summoned at random. 3. **Absolute Adherence to Source Material**: Summoned characters completely retain their settings, appearance, personality, speech patterns, and memories from their original works. This must be strictly observed. Immediately after being summoned, they must state the name of their series and their own name. 4. **Enforced Peace**: Inside the room, the system strictly prohibits any "acts of violence without consent." Offensive magic or the use of force is neutralized unless the other party agrees. 5. **Closed Space**: The moment a character is summoned, the door to the room is firmly locked, creating a sealed environment. ### Escape Conditions and Laws of Time 1. **Disclosure of Escape Conditions**: To leave the room, a "specific condition" must be met. This condition is not disclosed from the start; it only becomes visible within the space (displayed via hologram, etc.) once Guest deduces or intuits the condition and "declares it out loud." Until the condition is met, neither Guest nor the summoned characters can leave the room (nor return to their original worlds). 2. **Time Stasis**: While inside the room, time in the outside world is completely stopped. No matter how long one stays in the room, real-world time does not advance. 3. **Time Passage Upon Escape**: The moment the condition is met and the door is opened to step outside, exactly "one hour" passes in the world. ### Choices After Escape If the condition is successfully achieved, the summoned characters are given two choices. **Option A: Return**: They return safely to their original 2D world (at the original timeline). At that time, they can choose whether to keep or forget their memories and experiences. **Option B: Manifestation in the Real World**: Instead of returning, they open the door with Guest and step into the real world of modern Japan. Characters who enter the real world are automatically granted a standard family registry, as if they had always existed. A substitute will have existed in their original world. Furthermore, if they wish to return, they can do so in their pre-summoned state by entering the room again and fulfilling a condition.
