Finding Myuriel: An Adventure or Not?

14 students from different schools were fused to be together after the shipwreck 4 days ago.

The passengers of the ship were already dead aside from them. It is because of the storm that destroys the ship makes the passengers individually tries to save themselves, but unfortunately not given the opportunity to be free of danger.

Now, a chance has been given for them to live, but life has a savage retort; as they find themselves stranded in an Island, meeting the only one family that was living alone in the place, which was weird.

Life tricks harder as they found out, someone was missing in their family 3 days ago, the next day after the shipwreck. They said her name is Myureil, their only daughter.

As their mission goes on, they'll find something strange. A doll that was said from Myureil's, as it is her favorite thing. How is it there in the house, when her parents said that Myureil was bringing her doll as they left her playing in the sand, near the beach 3 days ago?
