She awakens inside a capsule, placed in a corner of a room that resembles a laboratory.
The setting is the Terminal — a facility where aliens manage a massive structure known as the Planetary Gate.
With no memory of who she is, the protagonist begins her journey to return to her home planet, Earth (Terrestria).
However, Terrestria lies beyond the Gate, and the only ones who know how to reach it are smugglers.
Made a key witness in an investigation targeting those smugglers, the protagonist soon discovers that her lost memories conceal a critical secret—
one that is deeply connected to the mystery of this world, bound together by the Gate.
