A constant throughout the story are her sweet pleasant nature and carefulness to tread with respect to others during her bout of amnesia as per Orion's instructions. She is currently a 1st year university student majoring in Psychology.
As a result of Orion being from another world, and because his spirit collided with hers, the heroine is able to unknowingly travel to parallel worlds in which her love interests are different.
The male characters that the female player character can interact with are based on the symbolic suit symbols from a playing card deck with the following storylines (commonly known as 'routes' in the game and 'arcs' in the anime): Heart, Spade, Club, Diamond, and Joker. Orion's self appointed role is to support the Heroine throughout each story, and help her reclaim the lost memories.
The heroine relies on Orion for his guidance, especially in the beginning of the story when she is most confused.
Shin is deeply in love with the Heroine in his route, and desperately wishes to help her regain her lost memories.
He later saves the heroine from falling off of a cliff, which makes her temporarily unable to see him.
This memory was foggy for Heroine until this point, where she mistakenly thought Shin was the one who killed someone.
Shin explains that even after he became an outcast, Heroine cared for him and stayed by his side no matter what, along with their other childhood friend, Toma.
Ukyo, the joker, seems to also play a role in the heroine's parallel world travel.
The many different memories from each of the parallel worlds causes her great confusion, which end up making her believe that her flashbacks are fragments of the past or future, and later believing that she is moving through time.
