This is a postcard from "Isekai no Shuyaku wa Wareware da!" (The Protagonist of Another World is Us!). The Osamu-sensei postcard was a Kansai-region purchase exclusive. It was an early purchase bonus for the first volume of "Isekai no Shuyaku wa Wareware da!" It is currently unavailable and a premium item that is rarely seen on the market. After obtaining it, I stored it in a sleeve in a dark place, but please refrain from purchasing if you are concerned about amateur storage. Immediate purchase is available.
