Even though magic-users are scarce among adventurers, this wizard was supposed to be just one ordinary adventurer.

He registered with the Adventurer's Guild, began tackling dungeons, and steadily gained experience—all in a perfectly normal fashion, though perhaps with slightly more efficiency than most.

Yet, as this adventurer continued his "normal" ascent through the ranks, the world around him began to veer wildly from the ordinary. It strayed far from the history it was originally destined to follow.

This is because the adventurer is privy to the true history the world was meant to follow, along with all its potential deviations.

The adventurer, known as Hiro, maintains his seemingly normal (?) adventurer's life, all while secretly operating as the "Black King," commanding invincible subordinates and his fortress, the "Sky Castle," to forge a future he desires—a future that should, by all accounts, be impossible!
