One: Kagayaku Kisetsu e#Plot

The main part One{{'}}s story takes place at a Japanese high school, though little is shown except for Kōhei's classroom, the cafeteria, and a little of the surrounding area. The main school building is three-stories, and the roof is accessible, albeit with a sign on the roof's access door saying "No Entry", but the door is never locked regardless. Adjacent to the main building is another which houses club rooms. The school borders a forest on one side with a chain link fence. Beyond the forest is a park with a fountain and a flight of stairs on a hill. Other than the school, the shopping district in town and the usual path Kōhei takes to school are shown, but otherwise the only other place depicted is Kōhei's two-story house.

One is a romance visual novel in which the player assumes the role of Kōhei Orihara.{{cite book|publication-date=October 1998|title=Tactics Moon & One: Kagayaku Kisetsu e Creation Original Picture Collection|year=1998|publisher=Compass|isbn=978-4-87763-014-0}} Much of its gameplay is spent on reading the story's narrative and dialogue. One follows a branching plot line with multiple endings, and depending on the decisions that the player makes during the game, the plot will progress in a specific direction. There are six main plot lines that the player will have the chance to experience, one for each of the heroines in the story. Throughout gameplay, the player is given multiple options to choose from, and text progression pauses at these points until a choice is made. To view all plot lines in their entirety, the player will have to replay the game multiple times and choose different choices to further the plot to an alternate direction. In the adult versions of the game, there are scenes with sexual CGs depicting Kōhei and a given heroine having sex. Later, ports of the game were released without the erotic content.

Kōhei Orihara is a young man in high school living a normal life. He tends to tease the girls he knows, especially his childhood friend Mizuka Nagamori, but deep down he is generally nice to girls. Mizuka usually takes good care of him, and worries about Kōhei, wondering if he could suddenly get a girlfriend. She is constantly sighing, being made to go along with Kōhei's meaningless jokes. Kōhei meets a transfer student named Rumi Nanase early in the story whose goal is to become a "true maiden" and to that end, she behaves maidenly toward those around her, but she shows her true character just to Kōhei, who leaves a terrible first impression. Kōhei gets to know a quiet classmate named Akane Satomura who does not readily open her heart up to those around her, and refuses any help Kōhei may offer.

Kōhei also meets a blind upperclassman named Misaki Kawana who has a sociable personality where she can be unreserved with anyone. A mute underclassman girl named Mio Kōzuki meets Kōhei one day and uses a sketchbook to carry on written conversations. She belongs to the drama club, and despite not being able to speak, can still show emotion through various abundant expressions. The last girl Kōhei gets to know is a childish junior high school student named Mayu Shiina who refuses to go to school. Her one and only friend she could trust in life, a ferret named Myū, dies shortly before she meets Kōhei and the other main characters.

The story revolves around Kōhei Orihara, the main protagonist. His father died when he was very young, followed by his younger sister Misao and finally his mother. Deeply depressed, he goes to live with his aunt Yukiko, his mother's younger sister, about ten years before One{{'}}s story begins on November 30, 1998. After he meets Mizuka Nagamori as a child, Kōhei begins to seclude himself in the Eternal World, a world within his mind. The game's main recurring motif is a focus on the Eternal World, a mystical alternate space which is never clearly explained, and the details of which are unknown. Shun Hikami's remarks in the original game are possible clues about the Eternal World.

The Eternal World is a place similar to the afterlife where a person's "other self" awaits. Anyone can access it, though it is only accessible once one has lost his or her grounding in the real world. It may be necessary to form a pledge with someone in the real world as a guide to the Eternal World, but one's memories surrounding the pledge become vague. A grace period can be granted between when the pledge is made and when someone goes to the Eternal World. Once the process has started, nothing can prevent someone from going to the Eternal World, and returning to the real world is difficult. Someone about to leave to the Eternal World starts to be forgotten approximately one week before going, and the amount of time before someone forgets differs based on how much someone thinks about the person leaving. However, he or she is remembered the moment that person returns. If a strong emotional bond is established in the real world before leaving, a person in the Eternal World can be returned after approximately one year.

Kōhei is living a normal life in high school with Mizuka, and gets to know five other girls throughout the story who he helps with their various personal problems. While Kōhei likes to joke and tease these girls, deep down he is nice to girls and genuinely wants to help them. In the story, Kōhei is able to form intimate relationships with the six heroines: Mizuka Nagamori, Rumi Nanase, Misaki Kawana, Mio Kouzuki, Mayu Shiina, and Akane Satomura. While a given relationship will start out well, before long those around him start to forget him as he begins to retreat further into the Eternal World. If Kōhei forms a strong bond with one of the girls, she alone remembers him even after he leaves to the Eternal World. This ensures his eventual return one year later when he and the girl reunite.

One: Kagayaku Kisetsu e is Tactics' third title, after Moon and Dōsei. One's production was headed by YET11, the pseudonym of Tsutomu Yoshizawa, who also contributed to the music in the game. Planning was led by Jun Maeda, who worked on the scenario with fellow writer Naoki Hisaya.{{cite web|url=http://erogamescape.ddo.jp/~ap2/ero/toukei_kaiseki/game.php?game=890|title=ONE ～輝く季節へ～ ErogameScape－エロゲー批評空間－|trans-title=One: Kagayaku Kisetsu e ErogameScape - Eroge Commentary Room -|publisher=ErogameScape|access-date=June 15, 2007|language=ja|url-status=dead|archive-url=https://web.archive.org/web/20110725101542/http://erogamescape.ddo.jp/~ap2/ero/toukei_kaiseki/game.php?game=890|archive-date=July 25, 2011}} Maeda wrote the scenarios for Mizuka, Rumi and Mayu, while Hisaya wrote the routes for Misaki, Mio and Akane.

The all ages OVA series was given a negative review by Carlos Ross of THEM Anime Reviews. Despite looking "kinda cute", he criticized the characters as having "no personality beyond the standard cliches of [a] dating simulation." However, Ross did praise the art style, commenting that it was "rather nice, being in traditional analog style rather than CG."{{cite web|url=http://www.themanime.org/viewreview.php?id=27|title=One: To The Shining Season|author=Ross, Carlos|publisher=THEM Anime Review|access-date=August 7, 2014}} The One: True Stories adult OVA series was reviewed at Mania.com where the reviewer remarked, "One: True Stories is the perfect kind of entry level or couples type of show that focuses just as much on the story and emotions of the characters as the sex, if not more so." The characters were found to be "appealing", and the story is described as a "fantasy but it's a nice fantasy."

Type-Moon co-founder Kinoko Nasu credits the PlayStation port of One as inspiring him to be a video game scenario writer. After he read a Famitsu review of the PlayStation port (in issue No. 538, dated April 9, 1999{{cite web|archiveurl=https://archive.today/20220218093852/https://jp.mercari.com/item/m88618893717|url=https://jp.mercari.com/item/m88618893717|title=週刊ファミ通 NO.538 1999/4/8 フロントミッションサード|publisher=Mercari|archivedate=February 18, 2022|accessdate=February 18, 2022|language=ja|url-status=live}}) that urged readers who normally dislike "orthodox romance video games" to try playing it because of its "science fiction elements," Nasu bought the game and became enthralled by its in-depth story. That made him realize that he could write an interesting story in a video game format, leading him to start writing Tsukihime and distribute a free promotional version of the game at Comiket 56 in August 1999.{{cite web|url=https://www.famitsu.com/news/201910/05182695.html|title=【FGO】奈須きのこ氏インタビューで迫る過去・現在・未来。第2部完結後の構想は2パターン存在(1/4)|publisher=Famitsu|date=October 5, 2019|accessdate=February 18, 2022|language=ja}}{{cite web|url=http://www.typemoon.org/works/kokuti.html|title=月姫無料告知フロッピー|publisher=Type-Moon|accessdate=February 18, 2022|language=ja}} Nasu also preferred how the text in the One PlayStation port is overlaid across the entire game screen, which was the format he used in Tsukihime, as opposed to the Windows version of One that has the text in a dialogue box on the lower portion of the screen. Illustrator and Type-Moon co-founder Takashi Takeuchi was already a fan of One at the time, but he preferred the Windows version. Nasu also said in a 2001 interview that the influence from One was so strong in his work at the time that even the manner in which the protagonist of Tsukihime talks is very similar to how Kōhei talks in One.{{cite book|title=Dōjin Game Maniacs|publisher=Kill Time Communication|date=July 2001|page=27|isbn=4-906650-96-1|language=ja}}

After the release of One: Kagayaku Kisetsu e, the game's producer YET11 was the only staff member who worked on the game who was later credited for future titles produced by Tactics, such as Tactics' next visual novel Suzu ga Utau Hi in 1999.{{cite web|url=http://erogamescape.ddo.jp/~ap2/ero/toukei_kaiseki/game.php?game=361|title=鈴がうたう日 ～a story of Angelic Girl, arrived the SunnyField.～ ErogameScape－エロゲー批評空間－|trans-title=Suzu ga Utau Hi ～a story of Angelic Girl, arrived the SunnyField.～ ErogameScape - Eroge Commentary Room -|publisher=ErogameScape|access-date=September 8, 2009|language=ja|url-status=dead|archive-url=https://web.archive.org/web/20101216133554/http://erogamescape.ddo.jp/~ap2/ero/toukei_kaiseki/game.php?game=361|archive-date=December 16, 2010}} The rest of the main production staff for One, along with its predecessor Moon, were later credited with the creation of the visual novel Kanon under the brand Key attached to Visual Arts.{{cite web|url=http://erogamescape.ddo.jp/~ap2/ero/toukei_kaiseki/game.php?game=187|title=Kanon ErogameScape－エロゲー批評空間－|trans-title=Kanon ErogameScape - Eroge Commentary Room -|publisher=ErogameScape|access-date=September 8, 2009|language=ja|url-status=dead|archive-url=https://web.archive.org/web/20071228084754/http://erogamescape.ddo.jp/~ap2/ero/toukei_kaiseki/game.php?game=187|archive-date=December 28, 2007}} Characters from One have appeared in other media not directly based on the One series. The six heroines from One have appeared in the Eternal Fighter Zero dōjin games by Twilight Frontier.{{cite video game|title=Eternal Fighter Zero|developer=Twilight Frontier|publisher=Twilight Frontier|platform=Windows|language=ja}} Additionally, Rumi Nanase can be seen as a background character in several episodes of the Kanon anime series by Kyoto Animation.{{cite episode|title=The Lieder ohne Worte Between the Elder and the Younger Sister|series=Kanon|series-link=Kanon (visual novel)|network=TBS|credits=Kyoto Animation|airdate= January 25, 2007|language=ja}}{{cite episode|title=The Disappearing Adagio|series=Kanon|series-link=Kanon (visual novel)|network=TBS|credits=Kyoto Animation|airdate=February 1, 2007|language=ja}}{{cite episode|title=The Contact Étude|series=Kanon|series-link=Kanon (visual novel)|network=TBS|credits=Kyoto Animation|airdate=February 8, 2007|language=ja}}{{cite episode|title=The Ronde Without You|series=Kanon|series-link=Kanon (visual novel)|network=TBS|credits=Kyoto Animation|airdate=February 22, 2007|language=ja}} Itaru Hinoue, the art director of One, included illustrations from One in her art book White Clover: Itaru Hinoue Art Works released in 2009.{{cite book|title=White Clover: Itaru Hinoue Art Works|publisher=VisualArt's|year=2009|isbn=}}

A sequel loosely based on the One visual novel titled {{Nihongo|One 2: Eien no Yakusoku|One 2 ～永遠の約束～||{{lit}} One 2 ~The Eternal Promise~}} was produced by the visual novel studio BaseSon, another brand under Nexton. One 2 was released first on April 26, 2002, and then again on April 25, 2003 with added voice acting, scenario, CGs and music.{{cite web|url= http://baseson.nexton-net.jp/one2/index.html|title=ONE2 ～永遠の約束～|trans-title=On e2: Eien no Yakusoku|publisher=BaseSon|access-date=June 16, 2007|language=ja}}{{cite web|url=http://baseson.nexton-net.jp/one2voice/index.htm|title=ONE2 with VOICE|publisher=BaseSon|access-date=June 16, 2007|language=ja}} One 2 used the concept of the Eternal World established in One as a major motif as One had done. The Eternal World in One 2 is better explained than in One, though the two versions of the world differ to a certain extent due to the scenario writers that worked on One not being credited on the production staff of One 2.
