Cyborg Girl

It is November 22, 2007. Jirou Kitamura (Keisuke Koide) is spending his 20th birthday alone. As he is buying a birthday present for himself in a department store, he catches sight of a 'cute girl' (Haruka Ayase). The girl, who also seems interested in him, follows him to a restaurant for his birthday meal, during which she suddenly states that it's 'her birthday too'. The two of them therefore exchange birthday presents. The girl, who seems unused to things as they are, behaves and speaks in a very bold manner- so much so that she rushes Jirou out of the restaurant without paying and provokes a chase after them throughout Tokyo. As the hijinks ensue, Jirou finds himself charmed by the girl. Unfortunately, after a few hours, the girl insists that she has to leave. After some mysterious words to him, she runs away, leaving him bemused.

The story then moves forward to November the 22nd, 2008. Exactly one year later, Jirou is celebrating his 21st birthday by himself in the same restaurant he ate in with the mysterious girl. All of a sudden, a girl who is the spitting image of her appears in front of him. This girl, however, has been sent to save him from a disastrous fate by a crippled future version of himself- she is, as his future self describes her, a cyborg modeled after the girl he met a year ago. Thus Jirou's strange life with the girl begins. Despite her 'cute' outward appearance, she is incredibly strong, and her behavior is erratic and otherworldly in comparison to other people's. She comes to Jirou's aid whenever he is in a difficult situation, and saves many other people's lives through her intervention.

Over time, Jirou not only becomes dependent on her, but also begins to fall for her. However, when it seems that she cannot return his feelings in the same way as he expresses them, he becomes irritated and forbids her to show herself in front of him again unless she can do so. He gradually regrets this, especially when it seems she is still doing things for him despite not being by his side. However, another disastrous incident which his future self hinted that he would have to suffer soon shows itself: a gigantic earthquake which completely devastates Tokyo as he knows it. As his apartment block collapses, the girl once again appears in order to help him- but this time, even her inhuman strength isn't enough to let her completely escape the consequences. After telling Jirou that she now understands his feelings, she is destroyed, and a distraught Jirou spends the next 61 years of his life trying to rebuild her. He eventually succeeds, although he passes away soon afterwards.

In that future time, a girl is alerted by one of her friends that there is a cyborg on display that looks just like her. Realizing this is the case, she is curious, and buys the now-shut down cyborg to experience the memories she has stored in her hard-drive. Intrigued, she fulfills her wish of going back in time to meet Jirou on his 20th birthday in 2007...
