Otome wa Boku ni Koishiteru

Otome wa Boku ni Koishiteru (処女はに恋してる), commonly known as Otoboku (おとボク), is a Japanese adult visual novel developed by Caramel Box and released on January 28, 2005 playable on Windows PCs. The game was later ported to the PlayStation 2 and PlayStation Portable (PSP) with the adult content removed. The Windows version was released in English by MangaGamer in 2012. The story follows the life of Mizuho Miyanokouji, an androgynous male high school student, who transfers into an all-girls school due to his grandfather's will.

The gameplay in Otoboku follows a branching plot line which offers pre-determined scenarios with courses of interaction, and focuses on the appeal of the six female main characters by the player character. The game ranked as the second best-selling PC game sold in Japan for the time of its release, and charted in the national top 50 several more times afterwards. Caramel Box went on to produce two fan discs released in 2005 and 2007 in Caramel Box Yarukibako and Caramel Box Yarukibako 2, respectively. Caramel Box later produced a sequel to Otoboku titled Otome wa Boku ni Koishiteru: Futari no Elder, released on June 30, 2010 playable on Windows PCs. Futari no Elder was ported to the PSP with the adult content removed. The story follows Chihaya Kisakinomiya, an androgynous male, who transfers into the all-girls school that was the setting of Otoboku. A third Otoboku game titled Otome wa Boku ni Koishiteru: Trinkle Stars was released on February 23, 2018 playable on Windows PCs.

A manga adaptation of Otoboku was serialized in ASCII Media Works' Dengeki Daioh, and a manga adaptation of Futari no Elder was serialized in Kadokawa Shoten's Comp Ace. Comic anthologies, light novels and art books were also published, as were audio dramas and several music albums. A 12-episode Otoboku anime produced by Feel aired in Japanese between October and December 2006, and an extra original video animation (OVA) episode was released in April 2007. Media Blasters licensed the anime and released the series in three DVD volumes. The Otoboku anime was generally panned in reviews at Anime News Network where the series was described as "cruelly unimaginative" with "obnoxious quirks and technical shortcomings". In a review of the anime by Mania Entertainment, the series is thought to be "very predictable and bland". A three-episode OVA adaptation of Futari no Elder produced by Silver Link was released between August and October 2012. An OVA adaptation of Trinkle Stars produced by EXNOA with animation by Blue Bread was released in January 2022.

Gameplay
Otome wa Boku ni Koishiteru is a romance visual novel in which the player assumes the role of Mizuho Miyanokouji. Its gameplay requires little player interaction as much of the game's duration is spent on reading the text that appears on the screen, which represents the story's narrative and dialogue. Otoboku 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. Every so often, the player will come to a point where he or she is given the chance to choose from multiple options. 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. Each scenario is divided into eight episodes, one interlude episode and an epilogue. At the end of an episode, an announcement of the next episode appears showing a preview of what is to consist in the next episode. Each episode takes place within the span of one month between June and March from episode one through the epilogue. The interlude episode is placed between the second and third episodes.

In the adult versions of the game, there are scenes with sexual CGs depicting Mizuho and a given heroine having sex. When the game was ported to the PlayStation 2 (PS2) console, the gameplay was somewhat altered. The PS2 version, and later the PlayStation Portable (PSP) version, both had the sexual content removed, and in these versions there is no evidence that physical relationships actually take place between any of the students.

There are ten additional sub episodes and a special sub episode. The CD and DVD Windows editions contain four sub episodes, the fan disc Caramel Box Yarukibako contains four sub episodes and a special episode, Caramel Box Yarukibako 2 contains two sub episodes, and the PS2 version contains six sub episodes, though the order in which they appeared was altered.

Setting
The primary setting is at a private all-girls school named Seio Girls' Academy, also called Seio Jogakuin Christian Education, which was founded in 1886 by Mizuho's ancestor. Seio was originally named Keisen Girls' Academy (恵泉女学院), which was used in original Windows version, the drama CD of the visual novel, and for the Caramel Box Yarukibako fan disc. This name was later ascertained to be similar to a name of an actual school, and the school's name was changed to Seio Girls' Academy (聖應女学院). Seio is used in the PlayStation 2 version, DVD Windows edition, Caramel Box Yarukibako Fukkoku-ban and anime series. The secondary setting is at a dormitory building named Sakura-yakata (櫻館), which Mizuho, Mariya, Yukari and Kana are boarding at. There are four other former dormitories named Tsubaki-yakata, Enoki-yakata, Hisagi-yakata and Hiiragi-yakata.

Main characters
The player assumes the role of Mizuho Miyanokouji, the protagonist of Otome wa Boku ni Koishiteru. He is a kind high school student who impersonates a girl at an all-girls school, which he transfers into per his grandfather's will. He spends his time with many fellow attendees, some of which live in the nearby dormitory, and enjoys helping them with any problems they may have. His childhood friend Mariya Mikado attends the school with him, and helps in his female transition. She has a spirited personality with a bit of a temper, and has been a support for Mizuho in the past. Mizuho meets a classmate named Shion Jujo who has a silent voice and demeanor; she quickly figures out that Mizuho is actually a boy, but tells no one. The previous year, she had to be hospitalized soon after she was elected as the Elder due to an illness.

At the dormitory lives an energetic first-year student named Yukari Kamioka. She is on the track and field team along with Mariya, who is her Oneesama (お姉さま), and has low confidence in her ability to run. Another first-year at the dormitory named Kana Suoin meets Mizuho on the day he moves in, and soon after Mizuho becomes her Oneesama. Kana is more than happy to serve Mizuho any way she can, since she admires him immensely. A hyperactive ghost resides in Mizuho's room named Ichiko Takashima and is shown to speak very fast when excited. She says that Mizuho looks very much like her previous Elder love interest, who turns out to be Mizuho's deceased mother. The student council president at Seio is Takako Itsukushima who tends to have a serious personality.

Story
Otome wa Boku ni Koishiteru revolves around the main protagonist Mizuho Miyanokouji, a male high school student. After Mizuho's grandfather dies, his will is reviewed, which explains his desire to have his grandson transfer to Seio Girls' Academy, the same one his own mother attended and his ancestors founded. Abiding by the will, Mizuho cross-dresses to attend the school. The headmistress, the deputy head teacher (visual novel only), Mizuho's homeroom teacher Hisako Kajiura and Mariya Mikado initially know his secret; Shion Jujo and Ichiko Takashima also eventually find this out. Mizuho is very popular among the other students, who often talk about how pretty, nice, and athletic Mizuho is. This rampant popularity escalates to him even being nominated against his will to join in on the Elder election. By these terms, the current student council president, Takako Itsukushima, runs against Mizuho.

The Elder election is an old tradition at Seio Girls' Academy where every June one of the students is elected by her peers to be the "Elder", who is seen as the number one "Elder Sister" in the school. Until her graduation, she is referred to by her peers as Onee-sama (お姉さま). To become an Elder, a candidate must gain at least 75% of the votes. If none of the candidates get at least 75% in the first round of voting, one of the candidates hands over her votes to another candidate, and the candidate who finally obtains at least 75% of the votes becomes the Elder. If there is no one else in the election, the current year's student council president becomes the Elder. In Otoboku, Mizuho gains 82% of the votes in the first round, effectively becoming the 72nd Elder in the school's history. After becoming Elder, Mizuho progressively gets more popular among the student body, since he is now a symbol of the school's excellence. In the following months, Mizuho starts to get to know some of the girls better and helps them with their problems.

Futari no Elder
Otome wa Boku ni Koishiteru: Futari no Elder is written from the viewpoints of main character Chihaya Kisakinomiya and secondary character Kaoruko Nanahara. Futari no Elder begins about two years after Mizuho's graduation. The main protagonist Chihaya Mikado was truant at his school because of harassment in the school and of a distrust in men. His mother cannot bear to watch him be in trouble, so she makes him transfer to Seio Girls' Academy, her old school. He dresses as a girl and introduces himself as Chihaya Kisakinomiya. Chihaya meets another protagonist Kaoruko Nanahara, who once rescued him from a playboy, and he begins to live in the dormitory building. He becomes the focus of public attention due to his attractive face and figure, and due to high grades at studies.

In the 75th Elder election, there are four finalists; Hatsune Minase hands over her votes to Kaoruko and Makiyo Shingyouji hands over her votes to Chihaya. Then Chihaya and Kaoruko gain the same votes of 368 together. Though a candidate which gains 75% or more of the votes becomes the Elder, Hatsune, as the student council president, proposes that both Chihaya and Kaoruko become the Elders; the motion is adopted unanimously. This is the first time there have been two Elders in the history of Seio Girls' Academy.

Development
Otome wa Boku ni Koishiteru is the fourth visual novel developed by Caramel Box. The scenario is written by Aya Takaya, and this was the first time Takaya was staffed on a Caramel Box game. Art direction and character design is done by Norita, who was staffed on Caramel Box's debut release Blue as an artist. The super deformed illustrations featured in Otoboku were drawn by the game illustrator Yoda. The music was composed by the music team Zizz Studio.

The original title uses the kanji 処女, which means "virgin", but is very close to the word for "young lady", shōjo. The creators added furigana subscript to indicate they wanted it read "otome" meaning "young maiden". Additionally, furigana was added above お姉さま to indicate that they wanted it read "boku". Despite the different kanji, the official reading is "Otome wa Boku ni Koishiteru". When the game was ported to the PlayStation 2, it was rewritten as 乙女はお姉さまに恋してる with the same pronunciation of "Otome wa Boku ni Koishiteru", which uses the actual "otome" (乙女) kanji. The latter name was kept for the manga and anime releases.

The limited edition achieved a ranking of four out of 50 in the ranking for the next two weeks.

Futari no Elder ranked second in terms of national sales of PC games in Japan in June 2010.

The English version of the original visual novel by MangaGamer was reviewed by Nicholas E. Mendes of NookGaming, who felt it had not aged well in some aspects, but was positive about the drama and comedy. In particular, he was surprised about the lack of dependency on tropes, despite having several characters that could easily fit into one.

The first two anime DVD volumes released by Media Blasters were reviewed by Anime News Network. In the review of the first DVD, the reviewer Carl Kimlinger generally panned the volume, commenting how the three episodes were "cruelly unimaginative" where "afterwards it's one long slide into a torturous hell of girls' school tripe where not even humor or romance can pierce the veil of pain." The Catholic girls' school premise is likened to Maria-sama ga Miteru and Strawberry Panic!, and is considered to be used "merely as visual spice". For the second DVD volume, Kimlinger wrote that "while the onslaught of squealing, caffeinated moe-bait has abated somewhat in its ferocity, a sagging of the already listlessly undirected plot ensures that the series' sophomore outing is only marginally more tolerable than the first." Further, the series is described as having "obnoxious quirks and technical shortcomings".

The first two anime DVD volumes released by Media Blasters were also reviewed by Mania Entertainment. In the review of the first DVD, the reviewer Chris Beveridge felt the anime reminded him of "parts of Princess Princess, especially when it came to the Elder status piece. It's even reminiscent of Strawberry Panic in this way." The series is described as "all about the "moe" factor, bringing about an atmosphere that makes you like the characters, care about them and feel good about seeing them interact. It does it well even if it doesn't have an amazing hook." For the second DVD volume, Beveridge commented that the series continues to be "very predictable and bland" which is "at this point fun but entirely forgettable". Beveridge also wrote how "the characters are all pleasant, nicely designed and with mildly interesting personalities that could lead to something more but never does."
