Day after day, Aki suffers from constant petty problems. Her classmate Mitsuki claims that the curse is the cause of her misfortune and that she knows how to get rid of it. Aki doesn't get a chance to ask more: Mitsuki mysteriously dies.
Rumor has it that one of her acquaintances is to blame. In an attempt to understand what happened, Aki performs a ritual called "Posthumous wish", which may solve the mystery of Mitsuki's death and lead to salvation.
