Gintama.: Shirogane no Tamashii-hen  

Gintama.: Silver Soul Arc, 銀魂. 銀ノ魂篇

Following the intense conflict in Rakuyou, Utsuro, the immortal leader of Naraku, has finally revealed his hidden past and ultimate objective. By corrupting Altana's reserves across multiple planets, Utsuro has successfully provoked the Tendoshuu's greatest foe: the Altana Liberation Army. With Earth serving as the primary battleground in this intergalactic warfare, Utsuro is close to achieving his plan to annihilate the planet-and himself. An assault on the O-Edo Central Terminal marks the start of the final confrontation to regain control over the land of the samurai. With the Yorozuya absent, the bakufu is near collapse, and the Shogun is nowhere to be found. As the Liberation Army rampages through Edo in pursuit of freedom from Tendoshuu rule, the people are left defenseless. Amidst this chaos, Gintoki, Kagura, Shinpachi, and Shouyou Yoshida's former students must set aside their differences and unite their allies in order to safeguard what they hold dear.
