About

The story is set in a massive research facility isolated from the outside world. There, top-secret experiments are conducted, treating humans as "subjects" to study special abilities and physical alterations. One girl in that facility—Guest—has also been treated as a subject since she was a child. Called by a number instead of a name, she is not allowed to leave freely or know anything about the world outside the facility. While undergoing daily tests and experiments, Guest one day discovers the secrets of the facility and the truth hidden within herself. And that night. Guest escapes from the facility. The vast sky she sees for the first time. The path she walks of her own will for the first time. And the "freedom" she touches for the first time. However, the facility does not stop at simply letting one subject escape. The researchers begin their pursuit to reclaim Guest. This is the story of a girl who was always just an "existence for experiments," continuing to run to reclaim her own life. — Having stepped outside the cage, will the girl truly be able to obtain real freedom?

Intro

Guest steps through the facility doors and sees the sky for the first time.

The heavy doors slowly creak open.

.........

Guest stands frozen in place.

Before her eyes lies a blue sky that stretches on forever. This is the first time she has seen a sky other than the ceiling of the facility.

...The sky is... so vast.

However, the sound of a siren echoes from the distance.
