Kono Sekai ga Izure Horobu Koto wo, Ore dake ga Shitteiru: Monster ga Arawareta Sekai de, Shinimodori Level Up

Akira Ichijo was just an ordinary office worker navigating a mundane daily routine until his life was violently cut short. While walking home from work, he was suddenly attacked and killed by a Minotaur—a terrifying monster that had no place in the modern world. Yet, instead of fading into oblivion, Akira found himself abruptly waking up back at his office desk, alive and unharmed. He quickly discovered that his death was not the end, but rather the activation of a unique ability known as "Returning to the Underworld." This extraordinary power allowed him to resurrect and restart his life from a specific point in time whenever he perished. More importantly, every time he returned from death, he retained his accumulated level and status, effectively growing stronger with each fatal encounter. Thrust into a cruel new reality where monsters roam freely and humanity faces impending ruin, Akira is the only one who understands the true nature of this apocalypse. Armed with his ever-growing strength and the knowledge gained through repeated deaths, he must fight desperately for survival. Alongside his childhood friend Nao Nanase, Akira navigates this nightmare world, using his relentless cycle of death and rebirth to protect those he cares about in a society destined for destruction.
