Flash back to the events of early 2019 as Franchouchou undertakes the concert that nearly results in their destruction, and then rejoin them in the early 2020 as they enter the final phase of their REVENGE.

Franchouchou's REVENGE hits a major roadblock as all of Saga is struck by a cataclysmic storm that leaves its citizens stranded, without power, and offline. But when the spirits of the living hit their nadir, it may just be the undead who give everyone hope.

Saga is still recovering from the damage caused by the major storm that devastated the prefecture, but the deadline for Franchouchou's REVENGE draws near. What started as the group's attempt to make up for a previous failure has now turned into a saga that may save Saga itself!
