Dagashiya Yahagi: Isekai ni Shutten shimasu - Teni-saki de Daihanjou

From the day he was born until the moment he died, 25-year-old Yusuke Yahagi never had a say in his life. Even after being hit by a truck and sent to a new world, he was given a job he hadn't asked for: a dagashi-ya. But the cheap and tasty snacks that line his shop are different from those back in Japan. From Curry Rice Crackers to Anzu Sticks, each item comes with its own special effects. Unfortunately, this new world has no idea what dagashi are! It's up to Yahagi to teach them about the wonders of dagashi as he builds a new life for himself, selling his stat-boosting snacks to help adventurers in need and earning loyal customers—like the lively pink-haired Meryl, the mysterious man in the silver mask, and maybe even a witch or two...?
