Shimazu doesn't die at Sekigahara. He wakes up in a war that never ends, surrounded by killers from every era of human history, and the animation moves like it was drawn by someone who actually understands how bodies break. The premise is a tournament of legends, but what hits is watching a real samurai try to lead soldiers who speak languages he's never heard, in a fight against an enemy that doesn't bleed the same way humans do. This is Hellsing's visual fever dream crossed with actual historical weight: every swing of a sword costs something, every victory feels like it shouldn't have happened, and the comedy lands hardest when everyone's covered in blood.

Shimazu Toyohisa is critically wounded at the Battle of Sekigahara, only to find himself in a white corridor lined with doors, facing a calm man named Murasaki. Sent through the nearest door, he wakes in a land of elves, dwarves and other fantastical races, where famous warriors from different eras of history have also turned up. Called Drifters, they are pitted against the Ends, a rival group of great warriors who command dragons, want to seize the world and aim to kill every Drifter. Teaming up with Oda Nobunaga and the archer Nasu no Yoichi, Toyohisa joins a war that is going badly for the humans of this world. The mix of action, adventure, fantasy and comedy sets sword-swinging battles alongside lighter moments.
