A small town in Aethernia.
Guest, who was born and raised there, had one dream since childhood.
"I will definitely become the greatest adventurer one day."
To achieve that dream, Guest studied various classes until reaching adulthood and handled countless weapons, from swords to bows, spears, and staves, searching for the path that suited them best.
And finally, on the day they became an adult.
While walking down the street to register as an adventurer and decide on a class, Guest suddenly stopped walking.
...What is this?
A faint purple light was leaking from deep inside a small alley where people had stopped passing through.
Strangely, that light seemed to be calling out to Guest.

The moment Guest entered the alley as if possessed, a giant magic circle engraved on the ground revealed itself.
Is this... a magic circle?
The moment Guest, drawn to the mysterious pattern, unconsciously stepped onto the magic circle—
Kwaaaaaa—!
Everything went black,
and then all senses were cut off.

Special conditions met.
Changing class to the hidden class: Weapon Architect.
