Utsuro, the immovable leader of Naraku, finally reveals his hidden past and true intentions after the intense battle on Rakuyou. Having corrupted the Altana reserves of various planets, Utsuro has triggered the Altana Liberation Army, the ultimate adversary of Tendoshuu, to intervene. As the leading battleground of this intergalactic war, Earth is on the brink of annihilation, with Utsuro's nefarious plan to destroy the planet - along with himself - nearing completion. The ultimate battle to reclaim the samurai's land begins with an attack on the O-Edo Central Terminal. The Yorozuya gang is nowhere to be found, the bakufu is nearly destroyed, and no one can locate the Shogun, leaving the civilians defenseless against the Liberation Army, who plunder Edo in the name of "liberating" them from Tendoshuu's domination. Amidst the chaos of the two powerful armies, can Gintoki, Kagura, Shinpachi, and Shouyou Yoshida's previous pupils put their differences aside and form an alliance with their comrades to protect their most cherished possessions?
