In a world of magic and monsters, he—Reulus—was born the child of a serf, possessing memories of a past life lived in modern Japan.

However, in a world where common sense and environment differed from his past life, his knowledge from that past life proved almost useless.

Poor housing, harsh labor, and meals he could never eat to his fill.

Even so, Reulus, who survived by relying on his past life's experiences, turned fifteen, reached adulthood, and was sold off as a slave.

But on his way to be transported to a mine as a slave, Reulus was attacked by monsters and barely managed to escape.

He had no family or friends to rely on, no home to live in, and no food or money. Nevertheless, having gained his freedom, Reulus takes his first step into this new world.

The place Reulus arrived at was Laval Wasted Town—a place run by people in circumstances not much different from his own.

To Reulus, with his past life's memories, that town was nothing but a slum, and there, Reulus begins life as an adventurer.

All Reulus wishes for is simply to live.

To live out his second life to the fullest, his harsh life in another world begins.

※This is an Isekai fantasy of swords and magic, featuring a reincarnated protagonist.
