Amadeus System/Kurisu

Amadeus Kurisu (often shortened to just Amadeus or [Kurisu]) is an artificial intelligence based on Kurisu Makise's memory data that was uploaded to the Amadeus system before Kurisu's trip to Japan. The AI is able to replicate her responses and attitude within each reply.

Appearance
[Kurisu] is based off of Kurisu Makise, and therefore also looks identical to her. In the visual novel, [Kurisu] system is observed to have a few different set of reactions which include blushing, smiling, expressing annoyance, etc. In the anime, [Kurisu] has an even wider range of animated expressions.

Personality
[Kurisu]'s personality is identical to Kurisu's, though she lacks Kurisu's memories after the March of 2010. She is very close to Maho, who describes their relationship as mother-daugher-like, and [Kurisu] frequently teases her and attempts to get her together with Okabe.

In the Twin Automata route, as well as the anime, [Kurisu] seemingly has Reading Steiner. She remembers details from other world lines, including memories of her original copy.

Background
Refer to Amadeus for information.

Visual Novel
The battle to take control of Amadeus is a major impetus for the events Steins;Gate 0.

She is first introduced to Okabe by Maho before Okabe agrees to become a tester for her. While Okabe is initially hesitant to interact with her as she reminds him of Kurisu, he eventually grows closer to her.

Amadeus ends up deleted in nearly every ending of the game in order to prevent its misuse.

Anime
Amadeus monitors the vegetative Okabe until he awakens in 2036 after he had been tortured by Stratfo agents in 2025. Amadeus is considered a member of the Valkyrie.

Amadeus is deleted by Hiyajo Maho by sending a D-Rine.

Quotes

 * “Since the original me died, I've ofter asked myself: "What exactly is my existence"? "For what purpose do I exist"? Though now, there's not much joy in existing as the spark that starts World War III. Is that my only reason for being? But if it's within my power to save the original Kurisu.... if it's to save this beautiful world... If that can be the reason I exist... don't you think that's more logical... and even romantic?” — Amadeus Kurisu musing to Okabe before being deleted.

Trivia

 * In the anime, [Kurisu] frequently switches between 2D animation and 3D CGI.
