In this chaotic world, it all started when they found an elf girl.

After being rejected by seven or eight Familias in Orario, Roy unexpectedly discovers that he can travel to different worlds, just like in a game panel, where he can improve his attributes by running dungeons and defeating bosses.
From then on, they embarked on a one-way road of leveling up and defeating monsters.
When they came to their senses, Roy was already standing at the pinnacle of the heavens with the Astrea Familia, and even the gods had to give way to them.
Standing before you is—
The terminator of the dark faction!
The strongest clan leader in Orario!
World heroes who vanquish the Black Dragon!
A super adventurer who conquers dungeons!
The first god-killer in a thousand years!
A harem king that even the gods would envy!
—Roy!
