One day, Kitsunezaki station became the unexpected refuge for two girls, Hiyori and Yui. Hiyori had lost her parents in a tragic event, while Yui was fleeing from her abusive father. The earthquake and tsunami had caused chaos in their lives, leading to identity issues at the evacuation center. Luckily, Kiwa Yamana, a kind elderly woman, came to their aid. Under Kiwa's guidance, Hiyori and Yui adopted new names, Moeka and Yurie, respectively. The trio then embarked on a new journey of living together in the charming coastal residence, Mayoiga.
