The World’s Strongest “Sword God” Unconsciously Dominates While Believing Himself to Be a Low-Level Swordsman ~A Story of a Man Who Was Reincarnated in Another World With Zero Magical Power, but Due to a Mistake by the Goddess, Ended up Training for a Thousand Years and, Before He Knew It, Had Become the World’s Strongest~

"Did I just defeat a regular bird?"

"It looks like a dragon to me!"

The protagonist, Izumi Yuuri, one day loses his life due to a certain incident and ends up being reincarnated in another world.

However, according to the goddess, Yuuri's magical power is zero. He is told that it is far too weak to survive in the other world.

So, before Yuuri was reincarnated into another world, he decided to ask for some time to train.

However, due to a mistake by the goddess, he ended up training for a thousand years instead of the time it would normally take to become a low-level swordsman.

Yuuri became the strongest in the world after a thousand years of training.

However, he set off to another world still under the impression that he had finally become a low-ranking swordsman.

"I'm just a low-ranking swordsman. I didn't get any cheats, so I will live steadily even in this other world!"

Yuuri makes that decision.

However, in another world, he mistakenly takes Fenrir as a mere dog and makes it his subordinate, mistakes the strongest dragon for a mere bird and defeats it in an instant, and saves a beautiful S-rank party renowned throughout the country from the shadows (without realizing it himself).

This is the story of the strongest swordsman without magical power who is unconsciously unbeatable.
