Izumi siblings Sagiri and Masamune are not related by blood. About a year ago, the two became step-siblings; however, soon after this new arrangement, their parents pass away tragically. The shock sends Sagiri into the dark corners of her room, where she keeps herself shut away from her brother and from society. Masamune is given the huge burden of providing for the family, which he does through his successful career as a light novel author. Strangely enough, Masamune has never met his light novel’s illustrator, Eromanga-sensei, known for drawing some of the lewdest things. Things take a strange turn when he finds out that his little sister was Eromanga-sensei the whole time, a discovery that brings a host of new challenges in the lives of a young sibling pair tackling the painful truths of real life all while making an impression in the light novel industry.

Much like Kakushigoto, Eromanga-sensei is heavily based on the concept of secrecy or hidden identity. Both anime feature characters who are involved in the industry of some kind of artistic medium, with Kakushigoto being based in the manga industry and Eromanga-sensei in the light novel industry. The two anime share a common theme with their secrecy element; that being that the main characters keep their real-life identities separate from their artistic personas due to embarrassment they feel because they draw erotic material.

Aito Yuuki is a perverted mangaka who doesn’t understand the feelings of characters in his stories and also feels constantly pressured by his editor. His desire is to draw panties. He works with his assistant, Ashisu Sahoto. Yuuki lacks experience with women and so he often asks his assistant to act as a reference, which often puts her into awkward positions all for the sake of the manga.

Kakushigoto and Mangaka-san to Assistant have the obvious similarity of being anime about mangaka or the manga industry in some way. Much like Kakushigoto, Mangaka-san to Assistant features the element of erotic material or eromanga being the type of work produced by the main characters, which is also the basis of the quirkiness of both shows.

Four young girls have a dream: they want to launch their very own manga magazine—the biggest in Japan! With the combined energies of Hana, the hyper enthusiastic editor-in-chief of this operation; editor-in-chief Aki and editorial staff members Tsugumi and Ringo, the Monthly Comic Earth Star is a glimmering possibility–but they have no experience in the manga-editing world whatsoever!

Like Kakushigoto, Mangirl! follows a group of people who are somehow involved in the world of manga. In this case, the characters are aspiring entrants to the industry while Kakushigoto’s Goto Kakushi is an established professional mangaka. Mangirl! and Kakushigoto also have similar comedic or gag-type feels to them which make them quirky and even sitcom-esque. Kakushigoto and Mangirl also share the moe element brought on by their cute girl characters, with Hana being the source of this energy in Kakushigoto.

Kawachi Daikichi is a thirty-year-old bachelor who earns an honest living and has fallen into the trap of routine in his life. When his grandfather passes away, he goes home to pay his respects; however, Daikichi is surprised to find out that his grandfather fathered an illegitimate child. The child is seen as an embarrassment to the family and no one wants to shoulder the responsibility of raising her. Daikichi is annoyed by his relatives and decides to take care of Rin, despite having no child-rearing experience.

The similarity between Usagi Drop and Kakushigoto lies in the relationship between parent and child present in both stories. While Usagi Drop’s main focus is this parental relationship developing in an extraordinary case, Kakushigoto has this relationship mainly defined by the father-figure’s insistence on keeping a part of his own identity hidden from his child.

Inuzuka Kouhei is a recently widowed high school teacher. He now lives alone with his daughter Tsumugi and struggles to juggle work and parenting. He relies on ready-made convenience store meals to feed Tsumugi. When she comments that they haven’t had dinner together in a very long time, Kouhei is frustrated by his own inability to provide Tsumugi with healthy and delicious meals. Luckily, one of Kouhei’s students, Iida Kotori, offers to host Kouhei and Tsumugi for dinner at her mother’s restaurant. When they arrive, they find out that the restaurant is often closed because Kotori’s mother is always away on work. Kotori begs Kouhei to bring Tsumugi around regularly so they can cook and eat a delicious homemade meal together.

Like Kakushigoto, Sweetness and Lightning is an anime with slice of life elements that is focused on the lives of a parent and their child. While Kakushigoto is more concerned with secrets and secret occupations, Sweetness and Lightning is focused on the life of a parent and child after the death of the other parent, which is something which Kakushigoto also seems to allude to so far into the series.

Nagami Yuu is an aspiring light novel author who often enters writing competitions but has never won one before. He is determined to become a better writer and after his latest failure, Yuu looks at the list of winning authors, zoning in on a Towano Chikai, an author who stood out at astounding margins. Yuu finds out that Towano is actually his sister Suzuka. She explains that she can’t let anyone find out her identity, asking Yuu to take her place as an author. He accepts the strange circumstances, at least until he manages to publish a book of his own.

Like Kakushigoto, My Sister, My Writer features characters who are involved in the industry of an artistic medium of some form. Kakushigoto deals with a mangaka while My Sister, My Writer is about light novelists; however, the two anime also have similar character relationships—the characters are blood relatives who were, up to a point, separated by a secret held by one of them.
