The **Replacer Incident** resulted in the collapse of the Replacer Syndicate.

## Prelude

The Replacer Syndicate previously tested various alternatives to the Qliphoth Factor on humans, to determine if any Factors will be sufficient for creating ideal replacer hybriders. Replacer Knight and Replacer Bishop both attempted to reacquire the Alternative Factor after the test subjects escaped from Replacer custody, resulting in both of their deaths. Eventually, Replacer King decided that the Replacers had gathered sufficient resources to put Project Terraside into action, and make King's vision for humanity a reality by forcibly converting all of humanity into replacer hybriders and collapsers.

## The Incident

### Terraside Terminals Deployed

The Replacers sent out various Terraside Terminals, also known as the Lost Ships, to turn the worldwide population in Normalside into Replacers. Yoo Mina and Joo Shiyoon were in an amusement park when the Replacers enacted their plan, and encountered Regenerated Knight and Regenerated Bishop there, who were tasked with protecting the Terraside Terminals. The two eventually broke off the fight when Knight and Bishop left to setup more Terminals.

A short time after the Terminals began to appear worldwide, the Administration issued an emergency alert due to the mysterious appearance of COs and proliferation of Corruption Syndrome, ordering the full mobilization of all TASKFORCE companies, regardless of their licensing. At the time the alert was issued, the Administration estimated that 97% of all land masses excluding Earth's polar areas would be affected by the Lost Ships within three months. Even worse, the Terminals were found to get stronger each time they are destroyed.

The full mobilization of all TASKFORCE companies caused Eternium supply to plummet, causing a serious risk of a global depression. Realizing the dire situation, Sylvia Cooper enlisted the help of Coffin Company and SWAT 4 for finding out where the Replacers are located, bringing Coffin in contact with SWAT 4 in the hopes they can find a solution. Coffin and SWAT 4 determine that Magellan's Prediction Society is their best lead for finding the Replacers' hideout due to their distribution of Elixir.

### Capture of Regenerated Bishop

Upon raiding the Society's headquarters, Magellan is mutated by Elixir concentrate and killed by Fenrir Squad and SWAT 4. Knight and Bishop, present in the compound, consider what to do. As Knight has the necessary amount of Replacer Factor, she retreats to supply the Terraside System Core as Bishop reveals herself to the invaders and surrenders. Bishop is then taken captive by Coffin Company.

As Bishop is imprisoned inside the Coffin, Coffin Company begins to transfer the prisoner to Coffin HQ, where Bishop would be transferred to Delta Seven. However, a Replacer strike team finds and greatly injuries Bishop before being routed by Mina. In order to get information on the Replacer HQ before Bishop's condition worsens, Mina meets with Bishop. The two join hands for 4 hours so Bishop can decode the location of the Replacer HQ. The Coffin then dives into the Counterside to evade a surprise attack from a Replacer fleet.

In the Counterside, ALT Squad and SWAT 4 board the landed Coffin. Yoon betrays Coffin, giving the coordinates of the ship to the Replacers, causing Knight and Queen to assault the ship. Queen then recovers Bishop, and leaves with Bishop and Yoon. However, Bishop secretly provided the coordinates of the Replacer HQ to Mina before leaving, allowing a counterattack.

### Assault on the First Immortal System Core

Following Regenerated Bishop's departure, the US Army Reserve was mobilized to assist against the Lost Ships across the world. Mina gives Sylvia the Replacer HQ's dive coordinates, and orders an immediate assault. SWAT 4, Fenrir Squad, and the Delta Seven operatives available prepare for the dive, while ALT Squad is ordered to return to Coffin HQ by Hilde. Once the team dives to the Replacer HQ, Sylvia explains that they must destroy the Replacer Factor Transmitter, and then the Immortal System, in order to foil the Replacers' plan.

After Kyle spots the Replacer Factor transmitter, Fenrir and SWAT 4 are sent to destroy it while Sylvia and Kyle lure Replacer troops. A structure believed to be the Immortal System appears after the transmitter's destruction, but before the group can attack it, Yoon arrives to stop them. The group pushes towards the Immortal System Core and breaks its barrier; with some help from Sylvia, Kyle calls in the Freedom Strike fleet; they bombard the Core, destroying it. This causes the regeneration of the Lost Ships in Normalside to stop completely for a short time, as the Replacer officers set up a second Immortal System Core elsewhere.

Queen arrives to assist Yoon, and demonstrates the power of the second Core by using it to destroy the Freedom Strike fleet, and cripples the Coffin. She mentions that the Core is located on the New Ohio, prompting Replacer King to reveal himself to Delta Seven. He orders Queen and Yoon to retreat to the New Ohio while Kyle gets a report that the Lost Ships in Normalside are regenerating again and are causing more serious corruption disasters. The New Ohio then dives, taking the second Core with it.

### Ian Mason's Plan

John Mason finds Fenrir Squad and shows them a recording of Ian Mason, explaining his history with the Replacers, and mentions a plan for how to stop them. John explains that Ian's plan can track the New Ohio by the Immortal System Core onboard, and can prevent the ship from jumping. John then leads Fenrir Squad and SWAT 4 to another group that he believes has the Eternium necessary to track the New Ohio - the R7 Irregular Scouts. John finds the scouts, and is led by them to a scammer who took their Eternium. The scammer is unwilling to poart with the Eternium, but after he is killed by a Category CO, John takes it so he can see Ian's plan through.

John takes the group to his safe house, where they link up with Jane Doe, Tommy and the Losers, Zhang Wei, the remains of ALT Squad, and Mark Finley. John explains that they must kill four of the Replacers' Abominations in order to deduce the New Ohio's location. The group is split into four, and they are sent into the Counterside using Drop Ships. After three of the teams kill their assigned Abominations, Shiyoon helps Mina use her Qliphoth Factor to defeat the large detachment of Replacers surrounding the final one. With the way cleared to execute Ian's plan, John places the Eternium acquired earlier beyond critical mass in the Drop Ship's Implosion Reactor and detonates it, allowing them to dive to the New Ohio's location. John also sends out the dive coordinates of the New Ohio so the other teams can follow.

The Drop Ship breaks apart while diving, causing the occupants to be separated. Shiyoon is found by Amy Firstwing and taken to Na Yubin, while Mina is forced to continue on alone, but soon joins up with ALT Squad after helping them defeat a group of Replacers. They are then ambushed by Yoon; while Mina and ALT Squad initially have the upper hand, Yoon prevails when Misteltein is unlocked. As Yoon preapres to execute Mina, she reveals that she's actually a mole, and turns on the Replacers. Yoon and a briefing from Machine G.A.P. explain the Administrator's plan called Operation Brain Death: Regenerated Bishop, the Arbiter of Project Terraside must die to make the Replacers lose control of the Immortal System Core. They successfully find and defeat Bishop outside the New Ohio, but Mina and Lin decide to spare her. Yoon tries to kill Bishop herself, but Queen arrives to save Bishop. Before Queen can kill the group, Jane disables the New Ohio's stealth field and dimensional jump system, forcing the Replacers to retreat to the New Ohio. The Administration sends in their fleet; the Enterprise uses its black hole drive to ground the New Ohio when it tries to attack.

### Assault on the New Ohio

Delta Seven leaves their ship and encounters Regenerated Knight, who is executed by Jake after a fight. Queen, dragging Pawn along, finds Delta Seven and attacks after Knight is regenerated. Mina finds and joins up with the other Drop Ship teams, and they hear sounds of battle between Delta Seven and Replacer Queen. They join the battle against Queen, but Queen uses the energy from the constant deaths of regenerated Replacers to create a halo - the regenerated form of the Nameless One. Hilde then drops nearby, activating her Qliphoth Factor. Hilde then attacks Replacer Queen as the other combatants watch from afar. With Queen barely able to stand, Hilde orders Mina to enter the New Ohio, and destroy the Immortal System Core.

Mina enters the New Ohio alone, finding Shiyoon. They go to the Engine Room, thinking the Immortal System Core is located there, finding Replacer King and Regenerated Bishop waiting. After King explains his motivations and intentions including a plan to distribute a Qliphoth Replica Factor to turn the world into Replacers, he offers to let Mina join him, but she refuses. As King attacks, Shiyoon suggests that they fight Bishop, as she is needed for the Qliphoth Replica Factor distribution. The two manage to hurt King enough to damage the Immortal System Core fused with him, but the progress to distribution continues. However, Bishop changes her mind and shuts down the distribution and System Terraside, causing her to die due to her integration with the system. Queen then arrives and urges King to escape; he does so using an emergency escape quantum tunnel. Mina follows King, who turns himself into a Replacer. Upon his defeat, Mina leaves as King is sent into imaginary space.

## Aftermath

Immediately following the death of King, the New Ohio was swept away by the collapse of King's quantum tunnel, and the known instances of Replacer Factor were destroyed. Global corruption rate caused by the Incident was stopped due to the destruction of System Terraside. Yumi also claimed that the end of the Incident caused the resolution of all Elixir related cases in the police.

With the total loss of the Replacer Syndicate's leadership except for Rook, the organization collapsed. Some Replacers were hired by Jehuty Biotech to assist Wilbur in creating new military products, and saw action against Horizon during her pursuit of Wilbur some time later. Rook cast aside her Replacer affiliation after she was taken by the Administrator, and lent aid in his future plans. Any surviving Replacer hybriders and collapsers likely turned into COs due to the loss of access to Replacer Factor. However, despite the collapse of the Syndicate and death of Magellan, Magellan's Prediction Society survived the Incident.

ALT Squad gained Administration licenses following the incident due to their exceptional efforts in defeating the Replacers. Orca and the rest of the R7 Irregular Scouts joined Coffin Company, renaming the squad to Eddie Squad. However, Fenrir Squad, and especially Yoo Mina in particular, were ordered to keep their involvement in the Replacer Incident a secret.

Hilde's use of Qliphoth Factor to defeat Replacer Queen made the beginning of a new Qliphoth Game a near certainty, which would later be exploited by the Knights of Redemption. Demon Lord Asmodeus also became more active following the incident, becoming bold enough to contact Hilde directly.

John Mason received a significant reward for his efforts, but the small fortune was stolen by Jane, causing John's company to remain in poverty.

A funeral was held for King, with Delta Seven officially claiming that he had been working undercover in the Replacer Syndicate integral to stopping the Replacers for good. Na Yubin also took the opportunity to provide Maria with the data that caused King to form the Syndicate during the funeral, as well as information for constructing Tech Level 5 gear. Maria reviewed the data provided by Yubin later, finding information on Project Terraside in the Nameless One's World.
