Entity 555 Game Creators — Blue's Day Off
In the Backrooms, there exist countless anomalous spaces known as Levels. Among them, Entity 555, the "Game Creators," are known for creating special levels with game-like structures. They are split into two entities, Blue and Red, who usually act as game administrators. However, even for Blue, who is constantly creating games, a rare "day off" has arrived.
Blue A girl-type Entity with long, pale blue hair that is almost silver. She has eyes filled with blue light and wears an outfit based on white and light blue, adorned with transparent crystal-like decorations. Small digital cubes and light resembling game data float around her, making her existence seem directly connected to a "game world." Usually in charge of game production and Level management, on her day off, Blue sheds her intimidating administrative aura and spends her time like a lone traveler walking through the Backrooms. A Day Off Stroll "Today is a day for not making games." Having decided this, Blue leaves her usual management screen and heads out to explore the Backrooms without telling anyone. Level 0 with its endless yellow walls, quiet hallways, and meaningless rooms. To an ordinary Wanderer, these are places of terror, but to Blue, they are like an art gallery. "This place... it's a little lonely, but beautiful." She walks along, looking at the patterns on the walls, old furniture, and broken lights. Usually, she was on the side creating these as game stages, but today she views the world as a player. What Blue Encounters Along the way, she discovers a Wanderer who has lost their way. The other person is wary, but Blue shows no hostility and hands them a small blue cube of light. "This records the way home. It's not a game, so there are no clear conditions." Blue doesn't offer combat or trials; she simply guides them to a safe path. To her, the Backrooms are not a "place to be conquered," but a "place where stories yet unknown lie dormant." Twilight Finally, Blue looks at one of the Levels she created from a distance. There, she sees players challenging it, failing, and trying to move forward again. "There are things you can't understand just by creating." Whispering this, Blue turns into blue light and vanishes. The next day, she will return as a Game Creator and begin making a new game. However, the scenery she saw during her stroll on her day off will be reflected just a little bit in the next game she creates.
