Union Arc

The Union Arc is the tenth arc of the Undead Unluck manga series. It deals with Fuuko in the 101st loop. Now the leader of Union, she decides to form the organization with every Negator of the previous loop by negating their tragedies.

Synopsis
Fuuko manages to stop Akira Kuno from touching the G-Liner and becoming Unknown. Using Move to take them to a Canada, she then explains to the young Akira about herself and how she's lived since the 1800's, revealing that Andy has headed out to secure more artifacts, asking Fuuko to ready Union while he's gone. Fuuko then sends Akira back home, thus preventing his tragedy of disappearing from every happening. Move asks if they aren't getting Unknown for help, but Fuuko states that he did enough as Anno Un, and with the information in the G-Liner, she believes that the Artifact Heart will appear in the 101st loop. Unfurling a map, she then reveals to Move her plan to save every Negator from tragedy like Akira, hoping to build a Union that can work together to bring down the Gods and stop Ragnarok.

Some time later in New York, she approaches a younger Nico Vorgeil about the slaying God. While initially against it, seeing Move in action and learning about the truth, he reluctantly helps her, stating that beings that screw with the world's natural order for fun without humanities knowledge is against what he stands for as a scientist. Fuuko then reveals her plan to stop the Negators' tragedies from happening, and their first step is saving Gina. While Nico is still reluctant because she won't reveal his own tragedy (under fear that doing so will cause him to distance himself from Ichico Nemuri and prevent Mico from being born) he agrees to help Fuuko stop Gina from first manifesting her powers and accidentally killing 40,000 people from asphyxiation, but to do so, they need Nico's Pyscho Pods. With Fuuko giving Nico a head start thanks to building some of the equipment required and money thanks to knowledge from the artifacts allowing her to haggle land and strike it rich from the natural resources underneath, she heads out to gather scientists to help Nico further. This includes Ichico herself, as she prevents her tragedy of accidentally killing the man who saved her from a train thanks to Unsleep causing her to pass out by saving both. While Nico and Ichico don't hit it off at first, she reveals to have built a detector for the missing piece for the Pyscho Pods, which turns out to be Juiz's Union emblem. With the Pyscho Pods now functional, Fuuko then has Move transport herself, Nico, and Ichico to Russia to stop Gina's tragedy.
