Synopsis: Isekai Kaeri no Ossan wa Shuumatsu Sekai de Musou Suru

Amidst a world overrun by zombies, Azami, a middle-aged man with exceptional abilities, draws all attention towards him. Having been called upon to a different realm three years ago, he fought as a samurai alongside his companions to triumph over the Demon King. Upon returning to Japan, he encounters a devastating reality filled with zombie hordes. Nevertheless, the skills he picked up in the Other World remain intact, driving him to embark on a journey to uncover the truth and locate any surviving humans. With his augmented strength and a motorcycle for transportation, he hacks through masses of the undead in various locations such as city hall, a police station, a school and even a hardware store. What lies ahead for Azami in this dire world?
