Vestal's Kitchen: Amnesiac Me and World Cuisine

Vesta is a boy with amnesia. Narita Natsumi is the manager of a hostel for foreigners. When she found Vesta in trouble with nowhere to go, she invited him to live at her hostel. Natsumi believes that the opportunity to taste foods from various countries shared by the diverse occupants of the hostel may help Vesta by triggering memories of familiar dishes.
