A Sister's All You Need (Japanese: 妹さえいればいい。, Hepburn: Imōto Sae Ireba Ii) is a Japanese light novel series written by Yomi Hirasaka and illustrated by Kantoku. Fourteen volumes were published by Shogakukan under their Gagaga Bunko imprint from March 2015 to February 2020. Two manga adaptations have been published by Shogakukan and Square Enix. A 12-episode anime television series adaptation by Silver Link aired from October to December 2017.

Plot

The story follows the novelist Itsuki Hashima who is surrounded by various people, including a beautiful genius writer who loves him, a big-sisterly college classmate, a fellow male writer, a sadistic tax accountant, and his editor. As the story progresses, the underlying conflicts of dreams and goals surface, as each character attempts to achieve their dreams, in their own way. One such example is the rivalry between author Itsuki and his friend Haruto. Itsuki's stories are driven by a passion for stories about little sisters with praise from a selective yet strongly supportive fan-base, whereas Haruto's stories are driven by victory and romance through more common, yet popular cliches. Each of their stories is riddled with common light novel themes and concepts, such as romantic comedy elements and erotic illustrations. They are all looked after by Itsuki's younger "brother" Chihiro, who in fact is his younger stepsister.

Characters

Itsuki Hashima (羽島 伊月, Hashima Itsuki)
Voiced by: Yūsuke Kobayashi[2] (Japanese); Stephen Fu[3] (English)
Itsuki is a 20-year-old author who has an obsession towards younger sisters. He is a novelist who debuted when he was in high school; all of his novels feature younger sisters as the heroine. In the span of five years, he has published 20 books, some of which have ranked in the top 10 weekly rankings for light novels on Oricon. Despite his success, his irrational personality and writing style has led to mediocre ratings compared to his fellow writers. His relationship with his father became worse when his father remarried Chihiro's mother only three years after Itsuki's mother died. He is in love with Nayuta, and towards the end of the series, he proposes to her. The series ends with him being married to Nayuta and them having a son named Sora.
Chihiro Hashima (羽島 千尋, Hashima Chihiro)
Voiced by: Nozomi Yamamoto[2] (Japanese); Arielle O'Neil[3] (English)
Chihiro appears as Itsuki's younger stepbrother, but Chihiro is actually a girl. She is a dependable person who looks after everyone around her. The reason why she hides her real gender is because their father thought she was in danger when he found out about Itsuki's obsession during his novel debut. She hides her true identity only in front of Itsuki and his acquaintances. Her main hobby throughout the series is housekeeping. Her true identity as a girl is revealed between volume 9 and volume 10, after an unintentional insult made by Nayuta.
Nayuta Kani (可児 那由多, Kani Nayuta)
Voiced by: Hisako Kanemoto[2] (Japanese); Jamie Marchi[3] (English)
Nayuta is an 18-year-old genius novelist who debuted after she won a newcomer prize. Nayuta Kani is her pseudonym and at first even Itsuki does not know her real name. She cannot write if she is not naked, has a slight obsession with personal nudity, and she likes dirty jokes. Starting in junior high school, she refused to go to school after getting bullied. After reading Itsuki's novel, she falls in love with him and will not hesitate to show it. She is also part-Russian. It is later revealed that her real name is Kazuko Honden (本田 和子, Honden Kazuko). At the end of the series, she is married to Itsuki and is pregnant with their first child.
Miyako Shirakawa (白川 京, Shirakawa Miyako)
Voiced by: Risa Taneda (1st drama CD),[4] Ai Kakuma (2nd drama CD & anime)[2] (Japanese); Sara Ragsdale[3] (English)
Miyako is Itsuki's classmate at college who at first had a bad first impression of him. While Miyako does not understand Itsuki's stories, she became his fashion advisor to help him with his novel. After Itsuki dropped out of college, Miyako still comes to see him. She has feelings for Itsuki but decided to support Nayuta instead. She is good friends with Nayuta and seems to be getting dragged into the latter's obsession with personal nudity.
Haruto Fuwa (不破 春斗, Fuwa Haruto)
Voiced by: Satoshi Hino[2] (Japanese); Alejandro Saab[3] (English)
Haruto is another novelist who debuted around the same time as Itsuki. Despite his cool appearance, he loves maid characters and owns a lot of adult games and figurines. Haruto has a "persona" in his social media to gain fans for his novel and to increase his series' popularity. He has a younger sister (Voiced by: Kaori Mizuhashi (Japanese); Kristen McGuire (English)) whom he thought is harsh to him, but is actually a sister who cannot be honest. His light novel series got a poorly-adapted anime because it was used as a tool for newcomer voice actors with no ability. In the middle of his shock, Miyako encouraged him and his hard work. He gained a crush on Miyako, however he found out about her feelings for Itsuki and decided to "keep going on his pace."
Setsuna Ena (恵那 刹那, Ena Setsuna)
Voiced by: Tsubasa Yonaga[2] (Japanese); Stephen Sanders[5] (English)
Setsuna is a 16-year-old illustrator who goes under the pen name "Puriketsu" (ぷりけつ). Setsuna was in charge of illustrating Itsuki's novels until Itsuki decided to stop because he thought his series is not worthy enough for Setsuna's art and asked him to wait until he is worthy enough. He dresses in Harajuku fashion and has an easygoing personality, even on deadlines. He has a butt fetish.
Ashley Ono (大野 アシュリー, Ōno Ashurī)
Voiced by: Manami Numakura[2] (Japanese); Amber Lee Connors[6] (English)
Ashley is a 32-year-old tax accountant who wears lolita fashion. She is reliable but sadistic; she makes her clients reveal their fetishes through their expenses, but raises their tax return in exchange. She is currently the only one among Itsuki's acquaintances who knows about Chihiro's real identity.
Kenjiro Toki (土岐 健次郎, Toki Kenjirō)
Voiced by: Kōsuke Toriumi[2] (Japanese); Eric Vale[3] (English)
Kenjiro is an editor at GF Bunko who is in charge of Itsuki's works. He looks like a typical office worker and is often seen drunk when overly stressed with his job, particularly when it comes to Itsuki and Setsuna's deadlines.
Kaiko Mikuniyama (三国山 蚕, Mikuniyama Kaiko)
Voiced by: Akane Fujita[2] (Japanese); Jad Saxton[3] (English)
Kaiko is an artist who is in charge of adapting Itsuki's novel Imōto no Subete (妹のすべて, The A to Z of Little Sisters) (Mahō Gakuen (妹法(まほう)学園) in the anime) into a manga. Her drawing skill level is so high that Itsuki becomes moved after seeing her works, despite her being a newcomer. She has an underwear fetish and refuses to draw a completely naked person, however then later changes her mind thanks to Nayuta. The ribbon she wears on her head is actually a pair of panties; she will wear them on her face before she draws.
