Ruri Hoshino (星野ルリ Hoshino Ruri?) is the narrator of and a supporting character in Martian Successor Nadesico television series and later the protagonist of Martian Successor Nadesico: The Motion Picture - Prince of Darkness. She was the Science Officer of the ND-001 Nadesico during the Jovian War.

Personality & CharacterEdit

Ruri is more intelligent than the rest of crew, and is seen as something of a "child prodigy" [1]. Ruri is often shown disparaging the inane antics of her older co-workers, usually by use of her catchphrase "baka bakka" (バカばっか bunch of fools?). According to her backstory, Ruri has a special affinity with computers due to genetic engineering, something that also affects her attitude towards others [2].

Skills & AbilitiesEdit

She is a talented singer, and her best friend is Omoikane, the ship's computer, which she usually consults if she has any questions about life in general.


Ruri was artificially conceived for the King and Queen of a nation called Peaceland, which was originally a theme park and casino and developed into a sovereign nation that is neutral in all planetary politics. But (Nadesico: "Echoes of Self, Echoes of Water")



The first appearance of Ruri.

She was recruited by Prospector and Goat Hory to become the science officer for the ND-001 Nadesico. While the Nadesico was docked at the Nergal she called Admiral Munetake an idiot as he did not like the fact Prospector and Goat Hory chose to recruit teenage girls over his own soldiers. When Yurika arrived on the brige, Ruri's reaction to her Victory Sign was that she too was an idiot. (Nadesico)

Twelve-year old Ruri is the product of DNA engineering and nanotechnology designed to create an "operator who could connect directly with computers". She was brought up in a laboratory-like school and educated in a manner that imparted knowledge without unnecessary information, such as emotion or communication with others. She is thought to be the only survivor from the experiments, but it is later revealed by Akito Tenkawa that another exists. Nergal was impressed with her abilities, and bought her to run the Nadesico's computer. Aside from her trademark "baka bakka" remarks about the crew, she is responsible for the opening narrations, and co-hosts the Get to Know Nadesico in-series instructional videos produced by Inez Fressange.

Akito helped Ruri save Omoikane from being erased by the military. (Nadesico: "Those Unforgettable Days")

When she journeyed to Peaceland to find out about her past, she took Akito with her as her "knight, much to Yurika Misumaru's chagrin. However, after learning of her past and who her parents and "real parents" were, she had no intention of returning and chose to stay on the Nadesico with her "complement of fools".

She is an orphan who was "bought" by Nergal Heavy Industries for the purposes of being the chief science officer for the Nadesico, which was actually to be completed six years after she had been adopted.

After the war, both Yurika and Minato Haruka entered into a custody battle over Ruri. When it became clear that the argument would never end, the Prospector decided to end it with a contest. Yurika and Minato would each grab hold of one of Ruri's arms and pull. As they pulled, Ruri cried out in pain, and Minato let her go. Prospector declared Yurika the winner, because she had proven that no matter what happened, she would never let Ruri go. Ruri was adopted by Yurika, and lived together with Yurika's new fiance, Akito, in his restaurant, where the three lived a "happy-comfy-life".

Ruri would later be devastated by the disappearance of Yurika and Akito, and was taken in by Minato, whom begins to realize her feelings for Akito. Eventually, she leaves to rejoin the military as a means to distract herself from her loss.


Ruri in movie

Ruri in movie

In the three years following the conflict with the Jovians, Ruri became the captain of the Nadesico-B (and later, Nadesico-C) and is the main character of the movie. She has matured a great deal in the time between the series and the movie. She is also apparently idolized by much of the navy, best illustrated by the reaction of Captain Arragi who is in charge of the escort for the Nadesico crew shuttle when it heads for the moon. Arragi (originally a Mokuren captain in the TV series) says that it is his privilege to escort the denshi no yousei (the electronic spirit/fairy). He records his conversation with Ruri and announces his intention to share it with the crew. Much of the story sees Ruri gathering many of the previous crew, including the trio of pilots led by Ryoko Subaru. There are two new additions to the crew, her executive officer Saburota Takasugi and a young boy named Hari Makibi. Hari is said to be the result of an experiment parallel to the one that produced her. Because of this, where Ruri is deadpan and maintains firm control of her feelings, Hari is emotional and tends to let his feelings get the better of him. Ruri views him as a sort of younger brother, while he has a fairly obvious crush on her. Saburota was a Mokuren commander and XO to Genpachiro Akiyama in the TV series. He serves as Ruri's XO on the Nadesico-B.

Ruri ruin form

Ruri as a ruin form in Assasin of Martian Successors.

Ruri encountered Akito, shocked that he was in fact still alive. Ruri would later meet Akito again at his and Yurika's "graves". However, he rejected Ruri's attempts to talk to him and make him a part of her life again, as he showed her the results of the experiments conducted upon him. It became clear to Ruri that the Akito Tenkawa that she once knew had died. Akito left, giving her his secret ramen recipe, because he could never again cook it for her.

Ruri was instrumental in the final defeat of the Martian Successors, using her meld with Omoikane to seize control of all enemy computer systems. They save Yurika, but Akito disappears, and Ruri promises that she will find him.


Notes & TriviaEdit

According to Keiji Gotoh, the movie version of Ruri was the easiest character he ever designed, her concept "popping into his head right away" [3]. Dan Kanemitsu, the English translator for Martian Successor Nadesico, notes that Ruri's phrase of "baka bakka" was one of the hardest lines in the show to translate from its original Japanese form [4].

Although not a star character in the television series, Ruri is very popular in moe fandom for a number of reasons, including her self-amused deadpan delivery. She is thought to be a major inspiration for later cutesy-looking girl characters who are sarcastic and jaded rather than cutesy-acting.

The character of Ruri was unexpectedly a favourite, and became popular among fans as a depiction of the moe ideal.[5] Because of Ruri's quiet, serious character and dead-pan expressions, she is often compared to Rei Ayanami from Neon Genesis Evangelion.[6] Hiroki Azuma believes Ruri to be directly influenced by Rei.[7]
