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. She appears as a supporting character in Steins;Gate 0.

Appearance
Being based on Kurisu's memory data, [Kurisu] resembles her.

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, she seemingly gains the memories of Kurisu through Reading Steiner just prior to her deletion.

Background
Amadeus Kurisu was created by Alexis Leskinen, Maho Hiyajo, and Kurisu Makise in order to test the Amadeus system. However, Leskinen, who possessed knowledge of the future from Kagari, had hidden motives to eventually use [Kurisu] to recreate Kurisu's Time Travel Thesis.

Plot
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.

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 start WWIII, 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 dont you think that's more logical and even romantic?"

Trivia
