Autumn Arc

The Autumn Arc is the sixth arc of the Undead Unluck manga series. It deals with the UMA Autumn's quest, a mysterious author Negator, and the pasts of both facets of Undead.

Synopsis
Realizing that To You, From Me possess prophetic qualities, Juiz has Fuuko and Andy investigate the manuscript and the author behind it. But as nobody knows how to contact them, Andy decides the only way is to create a manga and draw them out. With help from Union, they are able to create a manga called "Under + Unluck" and go to Shueisha HQ and find the manuscript, and discover it's still written in Japanese. Upon conforming that You-Me is a "book of prophecy", Fuuko realizes that there was nothing about Billy's defection, nor the current quests. Asking the interviewer Tahioka, they learn that three arcs that were shelved, one including Andy's past. Juiz then gives Fuuko and Andy the go ahead to contact Anno Un, which Fuuko does by using Tahioka's phone to call them. They agree to meet the both of them in the Stanley Bench in Canada in five hours. As they fly to Canada, they realize that Anno must be aware for not only them, but of Union as well.

At the bench, Anno approaches them without the duo even realizing it, but they state that while they do know everything, it's no fun if they explain it, before using the G-Liner to slay UMA Autumn's Juniors and wants the two to show them the "ultimate ending". Realizing Autumn is here, Fuuko and Andy try to fight it, but ignore Anno's warnings about being no match and the author is forced to chop off their own arm to allow them to escape. At Anno's house, they contact Juiz and asks her if they can train the duo. Juiz is against it, but concedes when Fuuko states that she trusts them and Andy wants to learn about his past and become stronger. Anno then re-creates Autumn's power to turn Andy into a book and has Fuuko to traverse it, so that she can learn Andy's past. While there, she interacts with Andy's younger self, known as "the Chief", and witnesses his previous crew being killed by bandits, with only him surviving thanks to his powers and then taking revenge against his killers. Him and Fuuko would then journey together for a while before she would eventually fade and head to another part of Andy's life, only to be intercepted by Victor, who wants to erase Fuuko's soul so he can take over Andy in a moment of weakness and kill Juiz.

As this happens, Anno is attacked by a younger Rip, who wants them to tell Under the future. Anno's past is then revealed, in that his real name is Akira Kuno, and his Negator power, Unknown, caused him to disappear from public consciousness and prevent himself from interacting with anyone after finding a G-Liner which was an artifact that had knowledge about the previous loops. While in despair due to being unable to interact with anyone, including his mother, he would create Yo-Me using the G-Liner and the information in it to interact with others.
