Missing Link of the Annihilator: Absolute Zero

Six months have passed since Rintaro Okabe, unable to change the past, chose to stay in a world line where Kurisu Makise is dead, discarding his identity as a self-proclaimed mad scientist. Suzuha Amane, the future daughter of Itaru "Daru" Hashida who had traveled back in time to convince Rintaro to help her prevent World War III, has been pretending to be Daru's sister to keep her identity a secret from her future mother, Yuki Amane. As Rintaro, still traumatized over his experiences with changing world lines, continues to refuse to help Suzuha, he attends a seminar held by Professor Alexis Leskinen and his assistant Maho Hiyajo. During the seminar, Leskinen and Maho present Amadeus, an artificial intelligence program based on Kurisu's research before her death. (Source: Wikipedia)

Maho then presents Amadeus, which runs an AI version of herself that was implanted with her memories four days ago, demonstrating that it is capable of its own decisions and behaves just like a human. Following the seminar, Rintaro speaks with Maho about the project, revealing that he was Kurisu's friend. Hearing about this, Leskinen and Maho invite Rintaro to converse with an Amadeus AI formed from Kurisu's memories of eight months ago prior to her death. Coming to Maho's lab, Rintaro is greeted by the Amadeus version of Kurisu, becoming surprised to find that her thoughts on time machines differ from what the original Kurisu told him. Afterwards, Leskinen and Maho recruit Rintaro as a temporary tester, installing an app on his phone allowing him to converse with Amadeus Kurisu and provide data. (Source: Wikipedia)

For the next 11 years, Rintaro's survival was kept secret between a select few resistance members who cared for him.

Speaking with a hesitant Rintaro through the night, Amadeus Kurisu tells him that she would be glad to sacrifice herself if it means finding Steins;Gate.
