Negator War Arc

The Negator War Arc is the twelfth arc of the Undead Unluck manga series. It focuses on the newly formed Union trying to stop a war in order to claim an important artifact and save the Negators that would create Under from their tragedies.

Synopsis
With the location of Remember now in sight, Fuuko reveals to everyone what it is and what her plans are for it, explaining she wants to hold off using it until they've gathered all the Negators Fuuko met in the last loop and then put it into a vote. Coincidentally, the artifact is in the middle of a war, the one where Billy, Tella, and Creed will awaken their powers in as they battle to claim an ancient super weapon called Disc. To have enough man power to stop the war, she recommends recruiting more members so they can enter the war and save the members of Under from their tragedies.

The first member is Yusai, who Fuuko saves after her awakened Undraw causes her and an UMA she battled against to be forced still for a week. The second is Haruka's grandfather Isshin the 12th, who with Yusai's directions and swordplay, is able to slay the UMA that killed Haruka's father in the previous loop. While initially against leaving due to the village rules, he quickly joins after being told what Haruka did in the previous loop. Finally, the Union is able to track down Sean and easily corner him before being subdued by Fuuko and forced to join.

With these new members, the Union enters the war to save both sides of the conflict, from the injured of "Horizon Balance", to Creed and his men. As each founding member of Under awakens their Negator abilities, the Union does all they can to protect them from the war and themselves. After stopping Creed, the entire war zone is carpet bombed by both sides of the conflict. To stop the war once and for all, Creed teams up with the Union to steal Disc as Billy sneaks aboard, wanting to see the Union's true motives. Fuuko then locates Billy on top of Disc, and after a short exchange to prove her Union's strength, he agrees to join if she can beat him in a quick-draw duel. Fuuko ultimately wins the duel by using Unluck to cause Disc to fall, and Billy, witnessing her teammates' undying trust in her, causes him to awaken Unfair, but with the condition now being he needs to acknowledge the Negator's strength to copy them.

However, when Disc threatens to kill Nico due to the effects of Unluck, everyone works together to try and stop it. Just as all hope seems lost, thanks to Ichico evolving her Negator ability, the separating of Nico's soul from his body allows it to take the completely physical stroke of Unluck as Disc and the island are blown to smithereens. In the wreckage, Fuuko finally finds Remember, and the would-be members of Under join Fuuko's Union. She then reveals their next step is space to save Phil from his tragedy.
