Moeka, 17, who had lost her parents, and Yurie, who was fleeing her violent husband, got off at a Kitsunezaki station one day. The massive earthquake and tsunami had altered their fates. Their lives were saved, but when they were asked about their identities at an evacuation site, they were perplexed. Kiwa Yamana, an elderly woman, stepped in to assist them. Yurie became Yui, Moeka became Hiyori, and the three women began a wonderful communal life together at the old house "Mayoiga" overlooking the sea from that day forward.
