Üc207Pr4f57t9，中文朱碧・多拉（部分譯名也稱休比・多拉）, nicknamed Schwi (シュヴィ, Shuvi) and later re-designated Preier/Prayer, 她是特圖向伊綱講述的「不被講述的神話」中出現的第一個機凱種。在故事中，她試圖了解人類的獨有語言——【心】，並被利庫發現。
外貌
朱碧與白有許多相似之處，但也有一些不同，其中最突出的就是從她背部延伸出的兩條尾巴，以及身體周圍露出的類似於機器的特徵。
她有着十分蒼白的皮膚，長而凌亂的黑髮（電影中為深紫色/栗色）及紅眼睛（電影中為黃色，有血紅色的曲線和黑色的瞳孔）。她非常瘦小。作為機凱種，她日常不穿任何衣服。
在與利庫以外的人類相處的時間裏，她身穿一件長袍來掩蓋身體的機械部分，用長袍的兜帽遮住頭部。但是尾巴沒法掩蓋（因為那是她的動力源），因此利庫決定把它解釋為裝飾品。雖然她確實很像白，但很有可能特圖只是把利庫和朱碧描述的很像空和白，藉此暗示這兩對之間的聯繫。這一點伊綱指了出來，認為特圖在故事的某些地方撒了謊。特圖片刻之後便承認這個故事確實並非完全真實，而是經過了些許潤飾。
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.
特長
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.
弱點
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.
歷史
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.
你知道嗎
- 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'.
