Utsuro's ultimate plan is revealed: spark a universal war that will ultimately lead to the destruction of Earth, allowing him to finally die but taking the universe down with him. Gintoki and others must team up with old allies and former enemies to not only defeat him but also the victims of the immortal's plans, a gathering army of vengeful Amanto who may no longer listen to reason....
Two years pass since the war and Edo rebuilds, changes and moves on, the most surprising and shocking change being the dissolution of the Yorozuya and the disappearance of Gintoki. While almost everyone wonders why and continues on their own paths, a new force lead by an old enemy rises up in the shadows with only one goal, to use Utsuro as a means to achieve immortality and power. Standing in their way is Utsuro's three disciples, but will that be enough when said three have their own agendas and may not work together?
