ウェスタの台所 ―忘れたぼくの世界ごはん―•Vesta no Daidokoro: Wasureta Boku no Sekai Gohan

Vestal's Kitchen: Amnesiac Me and World Cuisine

Kasumi works as a housekeeper at a boarding house exclusively for foreigners. She is then assigned to protect Haru, an amnesic boy who wandered into the house's garden. There are many mysteries regarding Haru's origins, and not even the residents could figure out his background. So, Kasumi makes a suggestion: "If we feed Haru various cuisines from around the world, he might find the taste of his hometown!" This story is a record of a boy who eats food from all over the world in order to regain his memories. (Source: Kadokawa, translated)
