A magical world where characters and kingdoms from Overlord, Attack on Titan, and Arifureta come together.
Synopsis:
Matt owns a strange shop that sells magical items that existed in the Multiverse.
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.
"Sir Eren, why don't you try buying the giant black sword? His name is Yoru."
"Sir 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."
"Miss Mikasa, please don't insist. I can't sell you that fruit; it's... cursed."
Matt doesn't know that the items he sells in his shop are incredibly valuable and grant great power to people. He only received the shop from a kind young lady, then.
Is Matt an ignorant man?
had potential, but the Mc besides being weak is an ugly middle-aged man. With all due respect, you can't put an ugly and weak guy in a harem fic.
