Üc207Pr4f57t9，中文朱碧・多拉（部分译名也称休比・多拉）, nicknamed Schwi (シュヴィ, Shuvi) and later re-designated Preier/Prayer, 她是特图向伊纲讲述的“不被讲述的神话”中出现的第一个机凯种。在故事中，她试图了解人类的独有语言——【心】，并被利库发现。
外貌
朱碧与白有许多相似之处，但也有一些不同，其中最突出的就是从她背部延伸出的两条尾巴，以及身体周围露出的类似于机器的特征。
她有着十分苍白的皮肤，长而凌乱的黑发（电影中为深紫色/栗色）及红眼睛（电影中为黄色，有血红色的曲线和黑色的瞳孔）。她非常瘦小。作为机凯种，她日常不穿任何衣服。
在与利库以外的人类相处的时间里，她身穿一件长袍来掩盖身体的机械部分，用长袍的兜帽遮住头部。但是尾巴没法掩盖（因为那是她的动力源），因此利库决定把它解释为装饰品。虽然她确实很像白，但很有可能特图只是把利库和朱碧描述的很像空和白，借此暗示这两对之间的联系。这一点伊纲指了出来，认为特图在故事的某些地方撒了谎。特图片刻之后便承认这个故事确实并非完全真实，而是经过了些许润饰。
人格
Before she made proper contact with humans, Shuvi's behavior was similar to that of a stereotypical artificial intelligence. She could absorb and process data and intelligence very quickly and act in the appropriate manner - a unique characteristic of her race.
However, she seemed to have difficulty in comprehending emotions and desires, otherwise characterized by her as the [heart]. Over time spent with Riku, she seemed to have started to develop her own [heart]. Her expressions and feelings became more vivid over time.
After setting her personality to mimic that of a "shy Imanity survivor", and spending a year around Riku's colony, she was unable to reset her personality back to the default monotonous mannerisms of the Ex-machina, stating that she was "stuck" in that mode.
特长
Like other Ex-machina, 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) and destroyed an 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 (without the use of magic, in which case it would have taken several minutes according to her).
Of the Ex Machina, she is one of the Prüfer, so she is particularly good at analysis. Despite this analysis of the [heart] took much time.
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.
弱点
The Ex-machina are a hive mind unit, however Shuvi was exiled from the unit due to various system and logic errors. Therefore, Shuvi was unable to access any of the 27451 artificial weapons stored in the Ex-machinas' linked arsenal until shortly before her death.
As she was robot and not a human, she was not very good at reading other's minds.
历史
During The Great War, she and 3495 other Ex Machina were involved in a battle against Aranleif the Ultimate and his seven followers, resulting in Riku's village being destroyed. Upon spotting Riku, she was puzzled by his reaction and decided that further analysis was required. However, her study generated an abundance of errors, which led to her disconnection from her cluster.
Meeting with Riku
Riku is searching through the Dwarves' ruin, and he sensed something. By the time he noticed danger, he is pinned down by an Ex-Machina. Realizing his doom upon violence, he surrendered himself. However, the female-like Ex-Machina surprised him with a kiss. After regaining himself, he questioned the Ex-Machina what is it up to, and the Ex-Machina answered that it is t learn the [Heart]. The two then leave the
"Ghost"
After evacuating everyone from the hideout. The remaining reformed under Riku and sworn upon the Six Pledges. They then each went out in their direction, moving behind the current of war. Shuvi remained with Riku to plant 32 Einwiek so that they can manipulate an attack to gain the Star Relic.
After they planted the 23rd and Riku's meeting with Shinku Nilvalen, Riku's body succumbed to the damage. He is treated by Shuvi, but still, lose his left arm and eyes, as well as his right arm damaged. He then rested for a day, and have Shuvi hold his hand in his rest.
Death
Despite Riku's request, Shuvi had gone out alone to execute their project. She successfully planted the 24th, but was caugt in a skirmish with Jibril, who sought to collect her head as a trophy, as the Ex-Machina have become one of the [Rare 5]. Jibril was unable to get her head in the end as she used Heavenly Smite on Shuvi, and she was completely obliterated. However, she was able to provide the data that Einzieg requires to inform Riku and protect the ring she got from Riku using magic (Kein Eintrag). She finally understood the meaning of love in her last moments before death.
你知道吗
- When Riku asks for the Ex-machina's name, she replies 'Üc207Pr4f57t9', to which Riku immediately responds by asking her for a more human name. Her first choice is Schwarzer (シュヴァルツァー) meaning 'Black One' in German, which interestingly contrasts with Shiro's name meaning white in Japanese. Eventually, they both settle with the name 'Shuvi'.
