Hououin Kyou... Rintaro Okabe. Is a test subject in using a new software from Victor Chondria known as the Amadeus. The reason is because he knew one of the developers, Makise Kurisu. At least he did... in another timeline. In this timeline she was dead. Killed by none other than Okabe. No one knows this, except himself. Soon he finds himself falling in love with the Amadeus Kurisu, that is when he realise he can no longer handle this piece of technology, and he has to tell the people relying on him. Thy warned him not to get too close. The professor was busy so he had only one other person to go to. Hiyajo Maho, the feisty young woman that looked like a small child, who has fallen in love with Rintaro.
