Shingeki no Kyojin- The Final Season - Kanketsu-hen Trailer

In the wake of Eren Yeager's cataclysmic actions, his friends and former enemies form an alliance against his genocidal rampage. Though once bitter foes, Armin Arlert, Mikasa Ackerman, and the remaining members of the Scout Regiment join forces with Reiner Braun and the survivors of the Marleyan military. Their meager united front sets out on a mission to stop Eren's wrath and—if possible—save their old comrade in the process.
