17-year-old run-away Yui and 8-year-old Hiyori, who lost her family and her voice, have no place to go when they run into Kiwa, a strange old lady. She offers them a place to stay in a banged-up old house overlooking the sea, a Mayoiga. The girls find comfort in the Mayoiga, a legendary house said to look after lost travellers, and the warm hospitality that Kiwa provides. Both the girls` damaged hearts begin to heal little by little. As time passes until one day, a variety of beings which Kiwa calls "Fushigitto" begin popping up around the house.
