Keshou Mitsuran was a researcher that work at a tire manufacturing company, and more than anything, he loved to eat. From savoury or sweet, whether it was a dish from full course dining or a simple snack from convenient store, he would try foods from various cuisines to add to his favorite food list. One day, on his way to try a new restaurant, he got caught in an accident and somehow ended up summoned to another world. With no apparent way to go back to his world, he joined the party that summoned him as an adventurer, hoping to travel a whole new world and try foods he had never seen before. Unfortunately, the foods in this new world seemed bland and lacked variation. As someone who can't stand eating the same food every day, Mitsuran decided to spread his culinary knowledge from his world as he traveled with his new companions, striving to make exceptional cuisine that worth a special journey.
