To help her father, who is losing his memory, Eveina enrolls at the Memoria Academy, where the research she needs is kept behind restricted doors. She is willing to lie, steal, and go where she is not allowed.
Then several hours disappear from her own memory. What remains is a bruise, wet clothes, and a man who expects her to recognize him. Arrogant and infuriating, he clearly knows more than he is willing to say. Eveina wants both to uncover his secrets and to crack his skull. He is not the only person at the Academy she has to figure out.
A science-fiction visual novel combining mystery, drama, and romance. As Eveina, the player decides whom to deceive, whom to trust, and whom to let get close.
