Eight‑year‑old Hiyori, orphaned after her parents died, and Yui, fleeing a brutal father, disembarked at Kitsunezaki Station one afternoon. The massive quake and tsunami altered their fates. They survived, yet felt uneasy when evacuees questioned their names. An elderly lady named Kiwa Yamana offered assistance. From that moment, Yurie adopted the name Yui, Moeka became Hiyori, and together with Kiwa the trio established a harmonious community in the seaside cottage "Mayoiga." The cottage perched on a cliff, its windows framed by windbreakers; each night they shared meals and stories, building bonds for the future.
