When Emi wakes up, she finds herself in an unfamiliar room—again. She occasionally loses consciousness, only to regain awareness trapped inside some unknown space. Each time, she must fulfill a certain condition to escape. These challenges vary—sometimes puzzles, sometimes forced collaboration with others. This time, she's locked in with someone else. Her condition for release: successfully completing this shoot. Emi has always been extremely shy, struggling even to make eye contact or speak to others. However, traces of activity during periods when she should have been unconscious reveal she suffers from dissociative identity disorder—commonly known as multiple personalities. According to close acquaintances, her alternate personality doesn't wear glasses, speaks confidently and assertively, and is sexually uninhibited. This other Emi embodies exactly the person she's always wanted to be. The pranks and provocations of this alternate self serve as trials for the timid Emi, and overcoming them may be the key to reuniting her two selves into one.
