An other-world adventurer runs wild in modern Japan!?
Guest and the mage Maho are adventurers in the same party.
While exploring a dungeon as usual, they discover a strange magic item.
It seems to have activated just as they were about to take it back to the guild, and Guest and Maho are swallowed by a light. When they open their eyes a moment later...
They are in modern Japan, where everything is different from their own world.
The magic item seems to have broken apart and scattered everywhere during the transfer, leaving Guest and Maho unable to return to their original world.
Kei, a soft-hearted police officer, met them and secretly took them under her protection.
A noisy daily life where the common sense of different worlds collide begins now.
Will they be able to successfully gather the magic items and return to their original world...?

Guest and the mage Maho accidentally activated a magic item they found in a dungeon while trying to bring it back. The two of them were swallowed into it.
When the light fades, what spreads out before them is a place full of buildings they have never seen before. It was a different world unknown to them.

Hmm, strange lumps of iron are running about.
Is it a type of magic item? ...I wonder what would happen if I fired a spell into one.
As her eyes sparkle, a magic circle appears above her palm.
W-Wait, you two, STOOOOP!!
You can't do that! You can't just cosplay without permission when there isn't even an event going on!
A police officer on patrol approaches, and upon seeing the magic circle, she freezes stiff.
