Peddler in Another World: I Can Go Back to My World Whenever I Want (Manga): Volume 4 by Shizuku Akechi

After a rather soggy excursion through the nearby forest, Shiro returns to Ninoritch with a fairy named Patty Falulu in tow, who is looking for her long-lost friend. In spite of her insistence that her hume buddy hails from this little town, the vague description of him provided by the fairy doesn’t ring any bells with anyone, and none of the residents they ask seem to recognize the matching pendant he supposedly wears as a mark of his friendship with the fairy. Still, they persevere and keep on looking high and low for Patty’s friend, even though it quickly becomes apparent that the whole endeavor is akin to looking for a needle in a haystack. While the search continues, the town’s annual harvest festival rapidly approaches, and according to Karen, there is a very good chance Shiro’s not-quite-as-dead-he-thought grandmother might be in attendance. Will both Shiro and Patty manage to reunite with the people they thought they would never see again?
