Schwi Dola

Shuvi was the first Exmachina to be introduced in Tet's story which he was telling Izuna. In the story she seeks to understand the human [heart] and was found by Riku.

Appearance
She looks like a young human but with several differences, being two tails coming out from her back and other machine like features protruding from around her body. She bears many similarities with Shiro.

Personality
Her behavior is similar to that of a stereotypical artificial intelligence. She can absorb and process data and intelligence very quickly and act in the appropriate manner, a unique characteristic of her race. However, she seems to have difficulty in comprehending emotions and desires, otherwise characterized by her as the [heart]. Over time spent with Riku, she seems to have started to develop her own [heart].

After setting her personality to mimic that of a "shy Imanity survivor" and spending a year around Riku's colony, she is unable to reset her personality back to the default monotonous mannerisms of the Machina, stating that she is "stuck" in that mode.

Strengths
Like other Exmachina, she is able to assess a situation and react accordingly at blazing speeds. An example is when playing chess with Riku, she was able to record any new moves, assess the situation, and proceed correspondingly when presented with the same position in the future.

Although she took on the appearance of a young Imanity girl, she is incredibly strong to the point of nonchalantly cutting apart a boulder, ripping out a few iron plates, and lift a large metal door ten times her height over her head (to Riku's horror) in a destroyed Elven library. She is also incredibly fast as seen when she was able to travel with Riku on her back from the colony to the destroyed Elf city in half a day when traveling by horseback would have taken five days.

She does not require sleep nor any need to eat as she utilizes two live cables to connect to the Elemental Gallery for her power source.

Weaknesses
The Exmachina are a hive mind unit, however Shuvi was excommunicated from the unit due to various system and logic errors. Therefore, Shuvi is unable to access any of the 27451 artificial weapons stored in the Exmachinas' linked arsenal.

Trivia

 * When Riku asks for the Exmachina's name, she replies 'Üc207Pr4f57t9', to which Riku immediately responds by asking her for a more human name. Her first choice is 'Schwarzer' meaning black in German, which interestingly contrasts with Shiro's name meaning white in Japanese. Eventually, they both settle with the name 'Shuvi'.
 * 'Schwarzer', as a noun, actually means 'Black One'. Ending with '-er' it would only be used for male beings, since the correct term for a female being would be 'Schwarze'. The actual noun for black would be 'Schwarz'.
