Eromanga Sensei (Japanese: エロマンガ先生, lit. "Erotic Manga Author") is a Japanese light novel series written by Tsukasa Fushimi and illustrated by Hiro Kanzaki. ASCII Media Works has published ten volumes in the series under its Dengeki Bunko imprint since December 2013. A manga adaptation illustrated by Rin began serialization in Dengeki Daioh in May 2014. An anime adaptation produced by A-1 Pictures aired from April to June 2017.
The story revolves around high school student Masamune Izumi who loves writing light novels. Having no artistic skill himself, Masamune always gets his novels illustrated by an anonymous partner using the pen name "Eromanga", who is known for drawing questionably perverted images despite being extremely reliable. In addition to balancing his passion and school, Masamune is also stuck with taking care of his only family member—his younger stepsister Sagiri Izumi. A hikikomori by nature, Sagiri shut herself in her room for over a year and constantly bosses Masamune around despite his attempts to get her to leave her room. However, when Masamune inadvertently discovers that his anonymous partner has been Sagiri all along, their sibling relationship quickly leaps to new levels of excitement, especially when a beautiful, female, best-selling shōjo manga author enters the fray.

After brimming with happiness, Masamune jumps back home through Sagiri's bedroom window, where they make amends and clear up some misunderstandings. A worried Sagiri believed that Masamune wanted to replace her with Elf as his new illustrator, which causes her to lock herself up in her room and spends time watching battle scenes and analyzing weapons to draw out better battle scenes and girls with larger breasts. Masamune tells a touched Sagiri the truth after showing her his manuscript, which tells a story about her. Masamune wants to publish it as a book, which would then earn them much money.

Masamune and Sagiri get to work together, with Masamune asking Elf for help writing a short story less than 60 pages, and Sagiri starting on her erotic art. After four days of training, and two days left before the deadline, Muramasa visits Masamune, and attempts to convince him to surrender and instead write novels for her, as well as explaining her past. Muramasa never found any novel interesting from the bottom of her heart, so she decided to write one herself for her to read. So far, there had only been one book that interested her, which was what Masamune wrote, and she wants to defeat Masamune as she cannot forgive him for starting a new romantic comedy series. Muramasa goes on to explain her dream, which took root when her first ever fan letter gave her book a one million score out of a hundred, and from then on Muramasa had been desperately creating a novel that she could find truly interesting and give herself a one million score out of a hundred. Afterwards, Sagiri appears and declares to Muramasa that Masamune is her brother and refuses to give him away. Masamune then rejects Muramasa, who leaves with her promise of defeating Masamune. On the day of the competition, Muramasa ends up being disqualified due to her manuscript exceeding the page limit, and Masamune wins. Muramasa confesses her love for Masamune, but he politely declines. Later on, Masamune receives a letter from Muramasa, who encloses her favorite notebook and a note describing how interesting his novel was and that she would give him a score of one million out of one hundred.|

During the trip, Muramasa becomes embarrassed with confessing her love for Masamune in public, and later declares that she will not write stories anymore as she had fulfilled her dream of reading a story she could give a one million score out of a hundred, which were Masamune's books. Later that day, Masamune shows Muramasa one of the latest fan letters written by a middle-school girl named Hana Umezono. He tells her that the girl's letters were always highly passionate and that they always encouraged him especially. Masamune then reveals that Muramasa was the one behind all those letters by pairing up their handwriting, which she confirms, and explains that while her current dream is fulfilled, she should keep striving to fulfill other dreams she has by continuing to write. Muramasa changes her mind and decides that her next dream will be to start a relationship with Masamune.|

|Back from the trip, Masamune decides to set off to Akihabara to watch the debut of his and Sagiri's new work while talking with her via VOIP. During the way, both of them recall their past. Masamune reminisces about the time when he wrote his first novel and published it online in a bid to occupy himself after his mother's death. At that time, seven-year-old Sagiri, who was an avid fan of his work, provided him with illustrations for the series while not revealing her identity to him. Masamune and Sagiri's interactions inspired each other to follow their careers as writer and illustrator respectively, and Sagiri decided to cease her conversations with him and dedicate herself to be a professional. Once reaching Akihabara, Masamune is apprehensive about the reception of the book, until he is reassured when a group of characters from Oreimo pass by while praising it. Upon returning home, Masamune is surprised upon seeing Sagiri out of her room and she reveals that she is training herself to eventually become able to leave home. The two then renew their promise to move forward and make their dreams come true, together.|

|Elf and Muramasa arrive at Masamune's house to fulfill their part of her bargain with Sagiri, that she would allow Masamune to go with them for the trip in exchange to have both pose for her. As Sagiri draws with the two posing as models, Tomoe arrives at Masamune's home and delivers him a copy of an erotic doujinshi that is inspired on his most recent work. Sagiri arrives and snatches the book from Masamune and after reading it, is determined to make her own version of it. After reading Sagiri's version, Masamune realizes that the main character's penis was incorrectly drawn, but is too embarrassed to explain it to Sagiri. He then calls Megumi for help to no avail, and Muramasa shows the others a sketch of Michelangelo's David Sculpture to prove Masamune's point. The episode ends as Elf and Muramasa leave, with Masamune watching in joy as Sagiri waves goodbye at them to see them off.|

Reviewing Eromanga Sensei, THEM Anime Reviews wrote that between the two principal female characters featured in the series besides Sagiri, Elf is the "better one" compared to Muramasa. The website also wrote, "Elf, like Masamune, is a 'light novelist', and she's apparently much more successful at it than he is. She goofs off most of the time, only doing actual writing when the mood strikes her. Elf is also a bit of an egomaniac- though in fairness, she DOES have a nice smile- and at the beginning of the show she moves in next door to Masamune. Of course she comes to love him- ALL the girls in this show love him. She at least does exhibit flashes of self-awareness, and even humor."
