Maria Arima, having witnessed the brutal murder of several family members, is understandably upset. She spends a few months sulking at home, and then suddenly leaves on a cross-country trip. Just when she thinks she’s going to return home, she pays a visit to Kisara Village and… doesn’t return. Kisara Village is a small settlement deep in the mountains of Shikoku, established by a wealthy retired financier to be a haven where artists can live a simple, uninterrupted life and focus on their work. Maria isn’t held hostage or imprisoned against her will. She can still communicate with her parents (although it becomes more sporadic as time goes on). She just… doesn’t want to leave.
So Maria’s father enlists the other members of the Eito Mystery Club to bring Maria back. Needless to say, the recovery mission does not go as smoothly as hoped…
