A Middle-aged Man Who Returned From Another World Becomes Unrivaled In The Apocalyptic World

Yanagi Azami was summoned to another world and spent three years fighting as a member of the Hero’s Party. After defeating the Demon Lord, the gate to his original world reopened. He said goodbye to his comrades: Iris the half-elf Saint, Rindou the Hero, and Lobelia the dark elf Great Sage. He returned to his apartment in Japan, expecting almost no time to have passed. Instead, he found that a month had elapsed. The world had changed drastically: zombies now roamed the streets, society had collapsed, and communication networks were down. His smartphone showed messages starting from a few days after his transfer, with warnings about assailants and a gradual breakdown of order. The last message from his kouhai mentioned heading to a shelter at the City Hall two stations away.Azami retained all the abilities he developed in the other world. He could channel magic power to enhance his physical capacities and weapons, and he possessed an Item Box ring that allowed him to store and retrieve objects. His unique Samurai class specialized in close combat and efficient magic power use with no capacity for external magic. He also retained the Skill "Always Battlefield," which integrated detection abilities. He adjusted the skill to sense hostile presences, confirming it worked on the zombies.Determined to find other survivors and reach the shelter, he left his apartment. He avoided main streets to remain unnoticed, fearing that if the government were still functioning, his exceptional power would draw unwanted attention. He used a metal bat to defeat zombies but found its durability poor. On the way to City Hall, he detoured to a home center to acquire a sturdier weapon. The store was heavily damaged and infested with zombies. After clearing a path, he obtained a crowbar and other supplies. While exploring, he sensed a weak presence on the third floor that was not a zombie. He found a barricaded staff room and entered. Inside was a young girl, curled up on a sofa, starving and dehydrated. She was wary but accepted the portable food and water he offered. She had not eaten for three days. As she ate, she began to cry. Azami told her to calm down and eat slowly. The story reaches this point, with Azami having found a survivor and beginning to decide how to proceed next.
