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. 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 accidentally killing 40,000 people through her powers. 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 Psycho Pods, which turns out to be Juiz's Union emblem. With the Psycho Pods now functional, Fuuko then has Move transport herself, Nico, and Ichico to Russia to stop Gina's tragedy.

In Russia, Gina, who is still upset over her grandmother's passing, is attacked by UMA Heat, which causes her to first manifest her powers. Thanks to Nico's Psycho Pods, he is able to contain Gina's powers, preventing Unchange from killing anyone. Fuuko then fights Heat by herself, where it's revealed that she has evolved her Unluck to imbue objects and tools that she cherish with misfortune, which defeats the UMA with a meteorite. However, the "meteorite" turns out to be Feng, who challenges Fuuko to a fight, as per their agreement that he must only kill UMAs, no one else. Fuuko obliges, and defeats Feng by combining her Unluck with the moves Shen taught her, causing the remains of Heat to trigger an explosion and defeat Feng. As she leaves, she explains to Feng about her master, and that if he wants to become stronger, he must meet and raise him. Feng leaves as per their agreement, but vows to kill both Sheng and Fuuko to negate her ideals about strength.

Later at Stonehenge, Gina gets her previous self's jakcet while Fuuko digs up Apocalypse to begin the quests yet again. However, she opts to pass many of the quests and receives penalties in order to fasten the time outside, allowing for the Union to reach the members of Under and the next tragedy. Eventually, she settles on the quests for capturing Void and neutralizing UMA Autumn, and by then, 26 years have passed in the outside world. With a now more advanced Union at their disposal, they plan to take on UMA Autumn first, as Void has yet to awaken his Negator ability. For the fight against Autumn, Fuuko decides to use the same trick Anno Un did back in the Autumn Arc and turn herself into a book so Gina can meet her previous self and become stronger. Once Fuuko sends Gina into her book, back to the 100th loop where they first met, 101st Gina meets the ghost of 100th Gina, and despite some initial misgiving the 100th had for Fuuko, 100th relents and gives 101st the knowledge to properly control Unchange when she sees that the jacket 101st wears is her own. With this knowledge, Gina now has the power to properly use Unchange, saving Nico and Ichico from Autumn, before cleaving it in two, killing it instantly.

Back at the base, Gina beings imitating her 100th loop's outfit as a form of respect, while Fuuko uses the Soul Caliber artifact to finally give Ichico some long deserved rest. Nico shows his feelings for her, but brushes them aside when being told Ichico could still see her. Just then, Bau informs the group that Yokezu has passed, and it will only be a mater of time before Void's tragedy happens. To deal with it, Fuuko takes the place of Void's opponent/victim, challenging him for the belt. While he initially sees her as just a fan, her continued perseverance and an exchange of blows has Void accept her request, with help from Nico altering his sponsor's memories to allow it to happen.
