Undead Unluck: Winter Arc

A blizzard unleashed by UMA Winter sets the stage as Billy receives word of the battle against Autumn—and the unsettling news that Undead and Unluck are changing. Juiz confronts him with long-buried truths: the artifacts were created as weapons to challenge God, and the Ark has only one loop left to give. She asks Billy to reunite with Union and place everything on Unluck to reach their shared aim of “defeat God,” but Billy refuses, forcing Juiz to question what he’s really after.

When Juiz realizes Billy intends to seize the Ark and Apocalypse, tensions erupt into a ruthless fight with UMAs drawn into the chaos. Juiz advances with unwavering resolve, while Billy answers with a pistol and the borrowed powers of other Negators—each convinced their own “justice” is worth the cost. Elsewhere, Andy and Fuko fly out with Autumn’s core to target UMA Summer, only for Billy—suspecting Apocalypse has been entrusted to them—to send assassins to bring them down from the sky.
