Reiji Miyajima, the mastermind behind the popular “Rent-A-Girlfriend” series, is making waves once again with his latest creation, “The Shiunji Family Children.” The upcoming anime adaptation, set to premiere on April 8, 2025, has unveiled a new character visual featuring Banri Shiunji, voiced by Chika Anzai.
Plot and Controversy
The story revolves around the Shiunji family, consisting of two sons and five daughters. The plot takes a controversial turn when the father reveals that the siblings are not blood-related, leading to unexpected romantic developments.
This premise has sparked debate among anime fans, with some expressing concern over the taboo subject matter. The series explores themes of forbidden love between characters raised as siblings, pushing boundaries in the romance genre and getting anime adaptation. One X User (Formally Twitter) commented,
“Why are y’all so obsessed with incest”
Another user replied to him,
“Fun fact : This isn’t incest..They are adopted”
Well, this manga’s anime adaptation has sparked debate among anime watchers about whether the plot is too incestuous to skip. However, the author of ‘Rent-A-Girlfriend’ is undoubtedly creating a ‘Sweet Home Alabama’-style anime.
Another user stated,
“It’s not incest if they live together but belong to different families”

The latest visual features Banri Shiunji, the eldest daughter of the family, on what appears to be a date at the Hotel Century Southern Tower in Shinjuku. Banri is described as a kind-hearted university student aspiring to become a nurse.
