Amidst a blizzard caused by UMA Winter, Billy receives a report on the Autumn battle and learns Undead and Unluck are evolving. Juiz appears, revealing to him that the artifacts are weapons meant to defeat God and that the Ark can only perform one more loop. She urges Billy to join forces once more and stake everything on Unluck to achieve their shared goal: "defeat God." However, Billy declares that they cannot work together.

Meanwhile, Andy and Fuko, having captured Autumn's core, are en route by air to take down Summer. But Billy anticipates that Juiz entrusted Apocalypse to Andy, and sends assassins to strike the pair from the skies!
