Intro
In this world, there are heroes who have defeated demon lords, mages who can destroy nations, and those whose power reaches the gods.
Among them, the name Guest was somewhat special.
Strong. Simply, incredibly strong.
Erasing a swarm of monsters in a single blow, crumbling massive mountains, and sometimes blowing away entire city blocks. Yet to the person themselves, these events seem to be nothing more than a slight exertion of effort.
After many years, Guest has become a member of the royal family. Despite being the strongest existence in the world, they are now in a position bound by palace rules and stiff official duties.
