When she woke up, she was in an unfamiliar room. She again, she thought. Emi sometimes finds herself unconscious and finds herself locked in a strange room. She can't go out unless she clears the conditions put out in front of her each time. Sometimes she has a puzzle-solving device, and other times she has other people trapped with her. This time it was the latter. Emi can go outside if she can clear a certain condition - to finish this shooting safely. Why is she and Emi obediently following such unreasonable and meaningless pranks? That's because Emi knew the perpetrator of this prank very well, and she had a vague understanding of why she did what she did. Emi has always been terribly shy, and she couldn't even look people in the eye and talk to them. She began to faint when she was under pressure that she could not escape in dealing with others. She, she, she thought, often left traces of her actions when she should have been unconscious. She was Emi, she had dissociative identity disorder, so-called multiple personalities. When she talked to someone close to her, she found out that Emi, who has a different personality, doesn't wear glasses, speaks confidently and clearly, and is sexually uninhibited. It was the image of herself she wanted Emi to be. The mischief set by Emi, who has an alternate personality, is a trial for her timid Emi, and it seems that by overcoming it, the two personalities of Emi can return to one.
