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.

Amadeus ends up deleted in nearly every ending of the game.
