You find yourself in a world where magic is a common sight, dragons are rare but exist, spirits roam the lands and people's souls hold a lot more potential than one might expect.
The player follows the predicament of Mariko Blairnot, a young woman who finds herself trapped in an eerie mansion with five other people who claim to have no recollection of their past. Mariko herself can only remember scattered bits and pieces of an event that supposedly happened years ago, involving the death of her mother and the appearance of a mysterious stranger who offered his help to her and her closest dragon companion, Isshin. With both of them nowhere to be seen inside of the mansion, Mariko and the rest of the cast investigate their surroundings, only to find more questions with no answers.
When someone comes up with a way that could help in getting their memories back, Mariko is presented with the option to pair up with someone for the experiment.
Who will you trust?
