{{Nihongo|'''''Planetarian: The Reverie of a Little Planet'''''|planetarian ～ちいさなほしのゆめ～|''Planetarian: Chiisana Hoshi no Yume''}} is a Japanese [[Apocalyptic and post-apocalyptic fiction|post-apocalyptic]] [[visual novel]] developed by [[Key (company)|Key]], a brand of [[Visual Arts (company)|Visual Arts]] whose previous works include ''[[Kanon (video game)|Kanon]]'' and ''[[Air (video game)|Air]]''. It was released over the Internet on November 29, 2004, for [[Microsoft Windows|Windows]], and is rated for all ages. The game was later ported to the [[PlayStation 2]] (PS2), [[PlayStation Portable]] and [[Nintendo Switch]], as well as mobile devices. The story centers on a man who comes across a malfunctioning robot in a dead city. The man, known simply as "the junker", stays with this robot for a time and attempts to fix the projector of the [[planetarium]] where the story takes place.

Key defines ''Planetarian'' as a "kinetic novel", since its [[gameplay]] offers no choices or alternate endings. Instead, the player proceeds through the story solely by reading. The story is written by [[Yūichi Suzumoto]] and character design is produced by Eeji Komatsu. The game's soundtrack was composed and arranged by Key's signature composers [[Magome Togoshi]] and [[Shinji Orito]].

A [[light novel]] of short stories set in the world of ''Planetarian'' was released in April 2006, and three [[audio drama]]s have also been produced. [[David Production]] produced a five-episode [[original net animation]] series and an [[anime]] film in 2016. ''Planetarian''{{'s}} story, artwork and music have been praised, and the PS2 version ranked first for console games in terms of satisfaction in 2007.

==Gameplay==
{{stack|[[File:Planetarian screenshot.jpg|thumb|200px|Text in ''Planetarian'' is displayed in a dialog box, here depicting the player character talking with Yumemi.]]}}
''Planetarian'' is a [[Apocalyptic and post-apocalyptic fiction|post-apocalyptic]] [[visual novel]] in which the player assumes the role of the junker. Unlike traditional visual novels, no choices are given to the player in ''Planetarian'' to advance the story, and there is only one possible ending; this is what Key referred to as a [[KineticNovel|kinetic novel]].<ref name="key" /> The player can choose when to advance to the next [[dialogue]] screen or put the game on auto play. In this respect, the player does not play the game as if it were a [[video game]], but plays it rather more like one would play a music track on a [[Compact disc|CD]] or play a [[DVD]] film. During gameplay, the player can choose to hide the text from view and go back to any previous lines.<ref name="VN-PC" /> The game can be saved at any point in any of the five save slots available, and a load option is available where the player can load any of the automatically saved chapter markers, or choose to load any of the manually saved games.<ref name="VN-PC" />

By length of story, ''Planetarian'' is the shortest of Key's games. Excluding the opening and ending sequences, there are 16 parts to the story; the first half is set within the planetarium while the latter half is set outside in the ruined city where the planetarium resides. The novel takes four hours and forty minutes to complete on auto play.<ref group="note">The stated time assumes that the default auto play speed is used, which allots 0.07 seconds per character with a minimum time of 0.3 seconds. This reflects about the average time it takes the text to be read aloud at a normal pace. Quick readers can easily go through the entire novel in less than half of this stated time.</ref> After the game has been completed at least once, two new options appear on the title screen. The first is a feature that allows the player to view twenty images of [[CG artwork]] observed in the game. The second option allows the player to listen to eight of the nine music tracks featured in the game.<ref name="VN-PC">{{cite video game|title=Planetarian: The Reverie of a Little Planet|developer=[[Key (company)|Key]]|publisher=[[Visual Arts (company)|Visual Arts]]|platform=[[Microsoft Windows|Windows]]|language=ja}}</ref>

==Plot==
[[File:Matsubishi 2.jpg|thumb|200px|right|Matsubishi Department Store, the real life counterpart of Flowercrest Department Store in ''Planetarian''.]]
===Setting===
The game is set in a [[post-apocalyptic]] world.<ref name="VN-PC" /> It is said that due to the depletion of natural resources, [[Overpopulation (biology)|overpopulation]], and the failure of the Space Exploration Project, humanity has virtually eradicated itself through [[Biological warfare|biological]] and [[nuclear warfare]], turning a once prosperous civilization into complete ruin, cast in darkness and poisoned by constant rain<ref name="story">{{cite web|url=http://key.visualarts.gr.jp/product/planetarian/story/|title=planetarian：ストーリー Key Official HomePage|trans-title=Planetarian: Story Key Official HomePage|publisher=[[Key (company)|Key]]|access-date=November 30, 2007|language=ja|archive-date=October 31, 2012|archive-url=https://web.archive.org/web/20121031134555/http://key.visualarts.gr.jp/product/planetarian/story/|url-status=live}}</ref> from [[nuclear fallout]]. One military invasion in the past was at [[Mare Nectaris]]. The bloodshed continues 30 years after the war in a [[Dystopia|dystopic]] world via automated war machines, which kill anyone trespassing into their territory. Of the remaining humans, there are those known as "junkers" who go around scavenging for anything in order to survive; the protagonist in the story is one.<ref name="VN-PC" />

The main location where most of the story takes place is the fictional Flowercrest [[Department store|Department Store]] in a derelict city. It is based on the real [[Matsubishi Department Store]] of [[Hamamatsu, Shizuoka]] in Japan,<ref>{{cite web|url=http://suzumoto.jp/d0605.htm|script-title=ja:完売お詫び＆例のアレ再び配布＆プラネタリウムと鰻と地ビール（突発性浜松アレ観光ガイド）|trans-title=Sold Out Apology & The Usual Distribution & Planetarium and Eel and Local Beer (Hamamatsu Sightseeing Guide Occurrence)|author=Suzumoto, Yūichi|publisher=[[Yūichi Suzumoto]]|date=May 25, 2006|access-date=July 8, 2009|language=ja|archive-date=February 9, 2012|archive-url=https://web.archive.org/web/20120209141346/http://suzumoto.jp/d0605.htm|url-status=live}}</ref> although the [[planetarium]] on the rooftop is fictitious. The onset of the story takes place within the planetarium which is where the protagonist first meets Yumemi. The most prominent feature in the room when a show is not taking place is the large black planetarium projector called "Miss [[Jena]]",<ref group="note">Jena is a manufacturing city in Germany, specializing in precision machinery, pharmaceuticals, optics and photographic equipment, and is home to the Zeiss optics plant. In 1926, the world's first modern planetarium was built by the Zeiss company in the Damenviertel district of the town. The projector in ''Planetarian'' is based on the [[Zeiss projector|Zeiss Universal Mark II optical planetarium projector]].</ref> which is placed on a stage in front of the seats. The planetarium has electricity when the protagonist arrives, but only for a short time. Once a year, for 168 hours, electricity in the planetarium is operational, but the projector is broken. The rest of the floors in the department store are in ruins; mold and rats run rampant.<ref name="VN-PC" />

:The protagonist is a nameless soldier living the life of a "junker"—scavenging useful items among ruined cities to survive. He enters a derelict city searching for undamaged goods and finds an abandoned planetarium on the roof of a building he first thinks is a military facility. There, he meets Yumemi Hoshino, a gynoid designed to look like a young girl who annoys him greatly due to her constant talking.<ref name="VN-PC" /> The protagonist has a tough personality that comes from trying to survive in a [[Dystopia|dystopic]] world. He carries a [[grenade launcher]] with him and covers himself with a waterproof coat to protect his skin from the toxic rain. For drinking water, his canteen has a water purifier that can purify the rain. He is constantly searching for rarer substances such as cigarettes and alcohol which can be sold at high prices.<ref name="VN-PC" />

;{{Nihongo|Yumemi Hoshino|ほしのゆめみ|Hoshino Yumemi}}
:{{voiced by|[[Keiko Suzuki]]|[[Jill Harris]]<ref name="fun1"/>}}
:Yumemi is a kindhearted but extremely talkative [[gynoid]] attendant of an abandoned planetarium; she is designed to look like a young girl. Yumemi is slightly damaged and completely unaware of the changes that have occurred in the past 30 years,<ref name="story" /><ref>{{cite web|url=http://key.visualarts.gr.jp/product/planetarian/character/|title=planetarian：キャラクター紹介 Key Official HomePage|trans-title=Planetarian: Character Introduction Key Official HomePage|publisher=[[Key (company)|Key]]|access-date=November 30, 2007|language=ja|archive-date=October 31, 2012|archive-url=https://web.archive.org/web/20121031134337/http://key.visualarts.gr.jp/product/planetarian/character/|url-status=live}}</ref> as none of the facilities and databases that she connects to exist anymore. Therefore, she treats the protagonist like a regular guest by calling him {{Nihongo|"Mr. Customer"|お客様|Okyaku-sama}}, speaks of the world as it was before the war, and fails to understand any information he tells her, other than things related to her job at the planetarium.<ref name="VN-PC" /> The name "Hoshino Yumemi" itself is a pun, and can be interpreted as {{nihongo|"dreaming of a planet"|星の夢見|hoshi no yume-mi}}. Yumemi is the only character shown to the audience of the game.<ref name="VN-PC" />

:Yumemi is very adamant about protecting humans and is happiest when she is helping those she serves. When she is unable to help someone, she gets terribly worried that she is incapable of offering assistance and must instead indirectly help a customer by directing him or her to someone who can. Protecting humans is her top priority and will even ignore previous orders to make sure no human is harmed when in her care.<ref name="VN-PC" />

===Story===
While dodging detection from war machines in a ruined city, the protagonist enters a building with a dome on the roof to search for usable supplies. Once inside the dome, he meets Yumemi, who offers to show him a special commemorative projection especially reserved for the 2,500,000th customer, although he is in fact the 2,497,290th customer. Despite his aggravation with her, he agrees to attend her show. However, the projector device, "Miss Jena", has broken down and is in need of repair. After he repairs it,<ref name="story" /> Yumemi starts the show, presenting a projection of the starry sky, something that cannot be seen from the surface because of the polluted skies. The power goes out in the midst of the show, but Yumemi proceeds through the rest of the event with no visuals at the request of the protagonist.

Afterward, both of them leave the planetarium, as Yumemi insists on escorting him back to his vehicle outside the city walls. The protagonist plans to transport Yumemi out of the city after her battery runs out and find a way to reactivate her. A machine the protagonist calls a [[fiddler crab]], due to its design, is guarding the entrance to the city in which he came from, and he devises a plan to destroy it armed with only a [[grenade launcher]]. After his initial plan fails and he is forced to face the machine front on, Yumemi tries to protect the protagonist, but is blown in half by the war machine's [[machine gun]]s.

Yumemi spends her emergency battery life replaying her pre-war memories to the protagonist using a tiny holographic projector on her ear. When the video fades, she reveals that she had known that the planetarium would never have more customers during the 30 years she was alone, despite her apparent infinite optimism up to this point. In her final moment as she "dies" in front of him, Yumemi ejects the memory card from her artificial brain for his safekeeping. Touched and completely shaken by the loss of the beautiful world she left in his mind, he throws away his gun and puts the memory card in his coat, before wandering off with a broken leg as the fallen war machine's automated backup units are closing in on the scene.

==Development==
''Planetarian'' is Key's fourth visual novel, and had a small staff of three main people that did the majority of the work for the game's first release.<ref name="key" /> Unlike previous Key titles, ''Planetarian''{{'}}s art director position was given to Eeji Komatsu instead of [[Itaru Hinoue]] who had held the position for the three previous games.<ref>{{cite web|archive-url=https://web.archive.org/web/20110722103203/http://erogamescape.ddo.jp/~ap2/ero/toukei_kaiseki/creater_allgame.php?creater=621|url=http://erogamescape.ddo.jp/~ap2/ero/toukei_kaiseki/creater_allgame.php?creater=621|archive-date=July 22, 2011|title=樋上いたる 関わったゲーム一覧 －ErogameScape－エロゲー批評空間－|trans-title=Itaru Hinoue Games Done at a Glance - ErogameScape - Eroge Commentary Room|publisher=ErogameScape|access-date=October 21, 2014|language=ja}}</ref> Komatsu was chosen not only because of his specialty in depicting mechanics and robots, but also because he could represent short scenes which touch on a robot's existence to reproduce a person's ideals. Furthermore, Key was not short on staff at the time, and was not forced to outsource the artwork of ''Planetarian''.<ref name="knsite" /> [[Jun Maeda]], Key's main scenario writer and project planner, was left out of the project, and [[Yūichi Suzumoto]] was given the position of planning and scenario.<ref name="key" /> The music, excluding a single piece composed by [[Shinji Orito]], was arranged or composed entirely by [[Magome Togoshi]], one of Key's signature [[composer]]s.<ref name="key" /> ''Planetarian'' was the first game under the brand name [[KineticNovel]] to be described by the term "kinetic novel".<ref name="knsite" />

In the original version, Yumemi is only voiced during the beginning and ending scenes, while other characters are not voiced. When ''Planetarian'' was released for [[Microsoft Windows|Windows]] [[Personal computers|PCs]] on [[CD-ROM]], Yumemi had full voice acting.<ref name="official-2007">{{cite web|archive-url=https://web.archive.org/web/20070104224128/http://key.visualarts.gr.jp/product/planetarian/|url=http://key.visualarts.gr.jp/product/planetarian/|title=製品情報 - Planetarian|trans-title=Product Information - Planetarian|publisher=[[Key (company)|Key]]|archive-date=January 4, 2007|access-date=February 10, 2012|language=ja}}</ref> The [[PlayStation 2]] (PS2) port offers full voice acting for the entire cast.<ref name="prototype" /> Other changes to the PS2 version include a higher resolution for the [[2D computer graphics|computer graphics]] and an extended soundtrack.<ref name="VN-PS2">{{cite video game|title=Planetarian: The Reverie of a Little Planet|developer=[[Key (company)|Key]]|publisher=[[Prototype (company)|Prototype]]|platform=PlayStation 2|language=ja}}</ref> All other later versions contained full voice acting.{{cn|date=May 2025}}

===Music===
{{main|Music of Planetarian}}
The visual novel has one main theme song, the ending theme {{Nihongo|"Hoshi Meguri no Uta"|星めぐりの歌|Song of Circling Stars}} sung by [[Mell]] of [[I've Sound]], an arrangement of the folk song by [[Kenji Miyazawa]]. The ''Planetarian Original Soundtrack'' was released on August 11, 2006, at [[Comiket|Comiket 70]] by [[Key Sounds Label]]; it was later re-released on December 28, 2006.<ref name="OST">{{cite web|url=http://key.soundslabel.com/discography.html?ksl0025/ksl0025|title=Planetarian Original Soundtrack|publisher=[[Key Sounds Label]]|access-date=October 20, 2015|language=ja|archive-date=March 5, 2016|archive-url=https://web.archive.org/web/20160305025325/http://key.soundslabel.com/discography.html?ksl0025/ksl0025|url-status=live}}</ref> The soundtrack contains one disc with twelve tracks [[Musical composition|composed]] and produced by [[Magome Togoshi]], and [[Shinji Orito]]; themes originally composed by [[Charles Crozat Converse]] and Miyazawa were remixed on the soundtrack.

;{{Nihongo|Snow Globe|雪圏球|Sunō Gurōbu}}
:This story occurs before the events of the war that brought the world to ruin; at this point, Yumemi has been working at the Flowercrest Department Store's rooftop planetarium for about ten years. One day, Yumemi begins to act strangely, culminating in her simply walking out and wandering around the town. The staff of the planetarium are bewildered, and one of the workers—a woman named Satomi Kurahashi—is ordered to go follow Yumemi and bring her back. Before long, Yumemi begins to run out of battery power.

;{{Nihongo|Jerusalem|エルサレム|Erusaremu}}
:This story occurs as the war reaches its height. The South American Unification Army receives reports of a rogue sniper operating deep in the jungles of [[Patagonia]], and sends a platoon under the command of Master Sergeant Murdock to neutralize the threat. However, the entire platoon is killed off one by one by the sniper, until only Murdock is left. All alone, Murdock catches a glimpse of this mysterious sniper through his binoculars—and is shocked to find that he gazes upon the figure of a beautiful [[nun]].

;{{Nihongo|Man of the Stars|星の人|Hoshi no Hito}}
:This story occurs some time after the events of the kinetic novel, as human civilization struggles in a losing battle against the poisonous rain. Three of the last inhabitants of a nearly abandoned underground [[fallout shelter]]—named Levi, Ruth, and Job—find a quaint old man collapsed in the snow outside the bunker. When they bring him down, they are surprised to hear the adults calling him "Man of the Stars". The children grow quite interested about his strange nickname, as well as the fact that they have never seen a visitor from the outside world. The old man recovers a bit and has the children help him in putting together a portable planetarium projector. This story offers an ultimate conclusion to the story in the kinetic novel.

;{{Nihongo|Tircis and Aminte|チルシスとアマント|Chirushisu to Amanto}}
:Identical twins Tircis and Aminte study alone in a world of their own. Tircis begins to wonder why he is studying and how long will it go on. This is the story of how the answer reveals itself to Tircis and Aminte.

| ShortSummary    = A man living the life of a "junker"—scavenging useful items among ruined cities to survive—enters a derelict city only to be chased by automated anti-personnel machines. He takes refuge in a former department store building and finds that it still has working electricity. On the top floor, the junker is greeted by Yumemi Hoshino, the friendly [[gynoid]] attendant of the department store's planetarium. Yumemi treats the junker as a customer and repeatedly implores him to watch a special presentation reserved for the 2,500,000th customer, but the projector is in need of repair. The junker attempts to leave the following day, but he has second thoughts after talking with Yumemi.

| ShortSummary    = The junker returns to the planetarium and begins repairs on the projector. Yumemi tells him that she has been in energy-saving mode for the past 30 years and is only active for one week in a year. Yumemi helps with the repairs by testing spare light bulbs for the projector. The junker brings up the subject of God, and suggests that Yumemi pray to the god of robots for the projector to get fixed sooner. Although Yumemi has no knowledge of a god of robots, she shows the junker a related holographic recording of her talking to the planetarium staff about a heaven for robots. The next day, the junker completes his repairs to the projector.

The junker discovers that the electrical power that had been running to the building has now permanently shut off. However, the junker tells Yumemi to continue the presentation with only her explanations. Following the presentation, the junker goes to leave the planetarium, but Yumemi is concerned over the junker's return home. He tells her he has a car not far from the planetarium, so she offers to escort him.

They come across a liquor store, and the junker finds a lone unbroken bottle of [[Scotch whisky]] inside. Close to the edge of the city, the junker sees a large search and destroy robot. The junker implores Yumemi to leave the city with him, but Yumemi cannot comprehend everything the junker is telling her about the abandoned city. Before he leaves to destroy the robot, the junker tells her to think over his offer and stay put. The junker fires a grenade launcher at the robot, but the grenade misfires, causing the robot to retaliate with a [[railgun]].

| ShortSummary    = The junker survives the attack and manages to hit it on his second attempt, but the robot continues to attack. Yumemi tries to intercede, but the robot blows her in half while the junker successfully disables the robot. Yumemi uses some of her emergency battery life replaying some of her memories from the planetarium using a holographic projector. The junker tells her that he had come to the city to take her to her new workplace where she can serve new customers forever. Assuming him to be the god of robots, Yumemi asks him not to split up heaven so that she may always serve humans. After Yumemi's batteries are depleted, the junker takes the memory card with all of her memories and exits the city. The junker is found by three other junkers collapsed outside the city walls, but he tells them that he is a starteller.
