【Book Adaptation & Comic Series Ongoing】

A young boy who died young from illness was called by "certain heroic spirits" from another world and crossed over to it.

It was a world where, after countless battles, individuals possessing immense power came to be known as <Demon Lords>.

Given a new life and the name <Merea> by the heroic spirits, the boy was raised on a snow-covered sacred mountain to inherit the heroic spirits' powers, but eventually, the will of the era molded even him into a <Demon Lord>.

Following a certain incident, Merea resolved to live in that world as "a hero to the Demon Lords."

This is the story of the man known as the <Lord of a Hundred Demon Lords> (Hyakuma no Aruji) and the hundred Demon Lords who followed him.
