## Plot

### Act 1

Delta Seven is developing its own Eternium reactor for its ships under Kyle Wong's supervision. Upon its activation during the testing phase, the reactor seemingly begins to emit dangerously high levels of Corruption rays, and a researcher believes it is about to explode. Kyle orders an emergency evacuation and the reactor's immediate shutdown, but the researcher notices the reactor's energy is distorting the dimensional surface and detects that an energy response similar that of a diving ship around the reactor.

Karin Wong and Joo Shiyoung appear as Kyle regains his senses. Kyle attempts to place the two under arrest, but they manage to overwhelm Delta Seven's forces and retreat. As they hide, Shiyoung wonders if they made it back to their home world, but Karin points out that the quantum phase difference between them and their surroundings, proving that they are not in their world. Shiyoung laments that the quantum phase difference means that can only survive 24 hours in the world they're in and jokes about staying permanently.

Meanwhile, Delta Seven guards confirm to Kyle that the intruders appeared near the the reactor but continue to wonder where exactly they originated from. They also inform him that they cannot request any reinforcements as the reactor's energy had disrupted communications, so Kyle orders them to send a detachment force to a nearby base for help while everyone else searches for the intruders. Shiyoung holds off Kyle's forces while Karin takes data on Delta Seven's Eternium technology, noting that it is much more advanced than the ones in their own world. Once Karin has the data, the two escape Delta Seven's forces again. Kyle calls them over an intercom and asks about their intentions, and Shiyoung responds that they intend to do "illegal dumping."

### Act 2

At Coffin Company, Lee Sooyeon informs Hilde that the Coffin detected the signature energy of a Qliphoth Factor user that they call the "Prey". Hilde heads toward the energy's origin — near an air force base in the Nevada Desert — to investigate, and Joo Shiyoon tags along as he wants to see what his master plans to do with the Prey. There, after eliminating the C.O.s in the area, Hilde and Shiyoon encounter Shiyoung at the base's exterior. Karin tells Shiyoung over a communicator that she is establishing a dimensional passage, but Shiyoung reports that there are reinforcements coming her way that may be too tough to handle.

Hilde demands Shiyoung to let her and Shiyoon pass, but Shiyoung holds off them long enough for a strong C.O. to appear: the "Prey" known as Nephil. Hilde realizes that Shiyoung must be an Exile, a resident of another world, and she and Karin are trying to transport Nephil out of their world because it was too powerful for them to defeat (Karin and Shiyoung had intended to send the C.O. somewhere in the depths of the Counterside but accidentally ended up here instead). Hilde then prepares to fight Nephil.

### Act 3

Shiyoung goes back to Karin. Karin, feeling guilt for moving the Nephil to the current world, mentions that she will stay in the current world to fight it, but Shiyoung tells her that Fenrir Squad will help them take Nephil down. Shiyoon explains that this world has the technology to easily take down Nephil thanks to the Administration, which doesn't exist in Karin's and Shiyoung's home world. Hilde and Shiyoon demonstrate their capabilities by taking down an incoming wave of Category 3 C.O.s, which moves Karin and Shiyoung enough to decide she'll fight Nephil with them.

As Fenrir Squad waits for the Nephil, Shiyoung and Karin find Kyle and ask him to help against the Nephil. Seeing Kyle's reluctance, Karin explains that she's the only remaining member of Delta Seven in her world and once again asks for Kyle's help. Kyle remains emotionally unmoved but agrees to help regardless in order to protect his people. Kyle leads the two to a warehouse so they may arm themselves with anti-corruption gear.

When the Nephil arrives, Hilde thinks she recognizes the C.O. but concludes that it is merely similar to what she thought it is. After Nephil is defeated, Karin breaks down crying, having avenged her comrades. Kyle then demands Fenrir Squad about who they are and how they knew so much about the Nephil, but Hilde has Shiyoon hypnotize Kyle with his powers to make him forget about the whole encounter and convince him that Delta Seven's experimental Eternium reactor exploded. After Kyle leaves, Shiyoon discovers that Shiyoung does not have Dragon Blood running in her and that her parents are still alive in her world. Hilde then orders the two exiles to return home, and they do so. On the trip back to Coffin, Shiyoon asks if they will eat out, and Hilde mentions that she snagged a credit card from Sooyeon, and that Shiyoon can order whatever he likes.

Sooyeon informs the Administrator that the incident will officially be reported as nothing more than an accident with the new reactor at the Air Force tech lab. She also thanks him for establishing the Administration.
