Matt is the owner of a strange shop that sells magical items from other worlds in Overlord.
Although Matt is unfamiliar with the world of Overlord, as he was a middle-aged man with little knowledge of anime or books, strange things happen around him.
-----
The story focuses more on the secondary characters who buy items from the shop. The customers see Matt as an ancient being who is in the shop and has some mundane problems.

“Mr. Hiyama, the staff I gave you is unique, of course. The staff made from the remains of Kel'thuzad is... magical, I'm not lying.”
“Why does this boy named Armin look like a girl? Never mind, I'll just give him an Ashbringer so he'll stop bothering me.”
“Miss Mikasa, you want a fruit... A devil fruit? Hehehe.”
Matt doesn't know that the items he sells in his store are incredibly valuable and give people great power. He only received the store from a kind young woman.
Is Matt an ignorant man?
