It was serialized in Media Factory's seinen manga magazine Monthly Comic Alive between March 2007 and November 2011, and was compiled into nine tankōbon volumes.

It was adapted as a 13-episode anime television series produced by AIC that aired between October and December 2009 on TV Tokyo.^[1][2] The series, which is set in a co-ed high school, is about Sumika Murasame, a 15-year-old girl who is secretly in love with her female best friend, Ushio Kazama. Ushio likes girls too, but is only into "cute" and "small" girls, while Sumika is tall, good at sports, and outgoing rather than shy.

Sumika Murasame is a high school girl who is in love with her female best friend Ushio Kazama, but is unable to confess how she feels as Ushio only likes girls she considers to be "cute" and "small", while Sumika is tall and athletic. Sumika discovers one of her classmates, a boy named Masaki Akemiya who likes her, started cross-dressing to catch her attention, but inadvertently was hired as a model. Sumika and Ushio get to know two girls in their class who are a couple, Tomoe Hachikusa and Miyako Taema; Tomoe wants to start a "girl's club" where only lesbians can join but is wrought with opposition. Sumika agrees to go on one date with Masaki, who comes cross-dressed as his female persona Akemi Yamasaki. Sumika becomes involved with her classmate Azusa Aoi, a quiet girl and aspiring writer who plans to attend a dōjinshi convention fueled by her love of yuri author Orino Masaka, which is the pen name of Ushio's older brother Norio. Sumika gets roped into helping Azusa and attending the summer convention as well, despite wanting to spend time with Ushio.

After the sports day competition and cultural festival, a short German high school girl named Charlotte Münchhausen (nicknamed Lotte), comes to stay at Sumika's home and dojo to train in karate. Sumika, who had quit karate because it is not "cute", starts training again to help in Charlotte's training, much to the joy of Sumika's father. Ushio is unhappy about Charlotte's training and merely wants her to be a gentle, cute girl. Charlotte gets sick after running in the rain during training, and after Ushio confronts her about it, Sumika lashes out, distraught how she cannot become any cuter or smaller. Following Tomoe's suggestion, a female karate club is formed with Sumika as the president and Charlotte as the vice-president. After Ushio starts realizing she has romantic feelings for Sumika, she starts to worry that Sumika may stop being friends with her. Masaki stops being a fashion model after being traumatically exposed as a cross-dresser.

After Sumika and her friends enter their second year of high school, two first-year girls named Mayu Semimaru and Koino Matsubara join the female karate club. Sumika is troubled over her relationship with Ushio, which has an adverse effect on her karate performance, much to the disappointment of Mayu. Sumika starts to get more involved with karate training to take her mind off of Ushio and in doing so, inadvertently distances herself from her. Ushio breaks down in depression because of this distancing, which results in Ushio breaking her arm, but is able to make up with Sumika. Tomoe accidentally implies to Ushio that Sumika has romantic feelings for her, much to Ushio's surprise, and Ushio finally accepts that she has fallen in love with Sumika but decides to become less dependent on her friend before confessing because she believes love will always fail for her. Meanwhile, Mayu realizes that she might have romantic feelings for Sumika as well, which distracts her in a karate tournament. Later, Sumika runs for student council president, though runs into various problems concerning rumours about her, and is forced to recede when Mayu ends up punching another student for insulting Sumika. As such, Ushio ends up becoming the new student council president.

The Hachisuka family is very wealthy and traditional, but they have no choice but to accept Tomoe's habits. She claims that "high school is all about being in clubs", so she tries to set up a "Girls' Club" for "girl-loving girls who had no choice but to enter a co-ed school".

Tomoe is the only one able to 'control' her; they are always together, and for this reason they had no friends before befriending Sumika and the others.

Aoi thinks that love between girls must be something completely pure and fragile, hidden away from people's eyes; for this reason she doesn't like Tomoe and Miyako's relationship, considering them way too blatant.

Whispered Words was written and illustrated by Takashi Ikeda. After joining an independent film crew while in college, Ikeda decided to start drawing on manga as a way to create projects all on his own. His second manga work was submitted to the Shogakukan magazine Big Comic Spirits and subsequently won a small award.^[3] Whispered Words was originally conceived as a one-shot manga by Ikeda.^[4] Media Factory featured it in this for in the March 2007 of its magazine Monthly Comic Alive before picking it up for full serialization a few months later.^[5] After Whispered Words was translated for North American release, Ikeda stated he was unsure if would ever create another yuri-themed manga.^[3] Ikeda later authored the yuri manga series The Two of Them Are Pretty Much Like This, which was serialized on publisher Gentosha's Comic Boost website between January 2020 and February 2022 and localized in North America by Seven Seas Entertainment.^[6][7]

Tim Jones of THEM Anime Reviews said he feared that the series would turn into "another Maria Holic" and said that the first few episodes were frustrating to him, but the perverted thoughts of Sumika were "kept in her head, not expressed out loud."^[27] He added that although they do not become a couple, it is shown that Ushio really likes Sumika, a subtle yuri relationship. He praised Tomoe and Miyako, an "openly lesbian couple," saying it is nice to see a "yuri couple in a romantic comedy with some bit of humility." He pointed out that Aoi is "a shy girl who loves yuri" and has a crush on Sumika, and was generally fine with the voice cast. He criticized the series music as "nothing to write home about, said that the visual quality of the show looks fine, and said that the show is "an example of a good show wanting to be great," but dragged down by annoying jokes. He further said the series is "older teenagers and up" because must of the cast are lesbians, along with some fan service, and called an episode where a male character, Masaki, dresses up in drag as one of the "most creepy, unfunny episodes" he had seen in a long time.

Carl Kimlinger of Anime News Network said that after the first episode, the "series goes on as if blindsided by its own longevity," spending most of its time, up to episode six, "drifting," and "rudderless" with antics of Akemiya, a cross-dresser, and two lesbian lovers (Tomoe and Miyako) "acquiring a pretty serious patina of goofiness in the process."^[28] He also said that the series is a "couple of steps above your average romantic comedy," having some perverse humor, saying it is blessed by "good...background artistry." Kimlinger says that if the show, after its first episode, "feels like a sequel to its first episode," then its a fun sequel with characters which are likable, laughs, and more. He concludes that the series is an "enjoyable and often very funny romantic comedy" while he says that the series never lives up to "the promise of that opening episode" and is visually bland.

Megan Gudeman of CBR said that the anime makes Sumika's crush on her friend, Ushio, "comedic," and said that there is enough "yuri representation throughout the cast to be considered a 2000s staple."^[29] Em Casalena said the series shows a relationship with themes "you'd find in any teen romance" but it is between "two openly lesbian high school students," with a focus on lesbophobia and being a "young gay student in Japan."^[30] Casalena also says that the story is "incredibly relatable" with those girls who are closeted likely finding "parallels between her life" and the events in the series.
