Emit (video game)

Tanaka Yuri, a high school student, is stopped at a crosswalk by an old man. He asks her what day and year it is, if there is a clock store nearby, and says the word "EMIT". Yuri later asks her parents about the clock store, and learns that it is now a bookstore.

A few days later, she is approached by a young man. He claims that he is the same old man from before, and he comes from another dimension where people are born elderly and age backwards. He also claims that he came to this dimension by using a portal which is now broken, and the only other one he knows of is supposed to be in a clock store. For each day he stays in this dimension, he will "age" one year, growing younger and younger until he turns into a baby and disappears. As he was a visibly old man when Yuri met him on the street, by his claim he would actually be very young. Yuri refuses to believe any of this and storms off.

Over a week later, while Yuri is preparing to take her English test, she sees a small, sad boy watching her from outside the school. Yuri realizes his similarity to the old and young man, and that he would be the right age if he really had been getting a year younger a day. She leaves the school and, working together with the boy, whose name is Ken, they sneak into the bookstore's basement, and discover the portal there. Before returning home, Ken admits he had been relying on Yuri because she looked exactly like his mother.

Later on in her room, Yuri is trying to figure out what the word "EMIT" could have meant, and laughs to herself she spells it backwards.

Yuri runs into an old friend she had lost contact with, Ichirou. She is happy to see him again, but he claims that they just reunited at a party last night. Yuri does not remember this at all, and Ichirou said she had not remembered him last night either, although she did say a word he did not understand, "Emit".

Yuri is confused by this. Remembering that the boy had said his mother looked just like her, she suspects that she may have crossed into our world. In an attempt to investigate, she returns to the bookstore, but when she attempts to check the portal she is pushed into it- by herself.

Awaking in the other world, Yuri finds it just as the boy describes, with old men and women running and playing in the park while children relax on the benches. She manages to meet up with Ken again, who has returned to being an old man, and he tells Yuri that his mother, whose name is Julia, has indeed fled to Yuri's world where she is viewed as being young and beautiful. Yuri attempts to return to her world, but finds that the portal patrolled by armed guards on this side.

A few days later, she and Ken are waiting outside the portal in the rain. Just as Ken had, she has aged a year for every day she has spent in the other world, and is now in her early twenties. Desperate and seeing no other option, she attempts to rush past the armed guards while Ken distracts them. She succeeds in making it back to the portal, but is shot, and falls unconscious.

Back in Yuri's world, Julia has taken over Yuri's life and deeply enjoying herself. In exchange for Yuri aging in Julia's world, Julia is staying young. However, Ichirou has grown suspicious. Although he originally thought Yuri had simply forgotten him and gotten more mature, he has become convinced that the second Yuri he met is the real one and that someone has taken her place. He shares his suspicions with Yuri's mother, who has had similar doubts.

At the same time, Yuri staggers home. The shot grazed her shoulder; she is in pain but alive. Collapsing onto the sofa, she is interrupted in her moment of relaxation by Julia wielding a knife. She stabs for Yuri's face, but Yuri dodges, and attempts to talk it out. She tells Julia that Ken is worried about her, but Julia still refuses to return. Then, Ichirou and Yuri's mother enter. Before they can arrive, Julia flees.

Yuri tries to explain the situation, but Ichirou grabs her wounded arm, still thinking she is Julia. He stops when she cries out in pain. He asks her if she is the real Yuri, and is convinced when she is infuriated that he would even ask.

Days later, Yuri is healthy and has returned to her normal age. Ken has returned to Yuri's world to retrieve his mother, who, now that Yuri has returned, has resumed "aging", and is now a small girl. Although they all part on good terms, Julia is reluctant to leave Ichirou.
