This could turn out to be a sweet series, or a super creepy one.

Earlier today, an official website for the Imouto sae Ireba Ii (If I Only Had a Little Sister) anime opened its doors. The site confirms that the show will air this fall, though no details have been confirmed.

A teaser visual was also posted, which you can check out below:

The series was originally mistakenly unveiled in a posted listing for Imouto sae Ireba Ii volume seven, which featured a preview of the book’s cover. The novel will hit retailers on May 18 in two versions: a normal edition and a Special Edition that includes a drama CD.

Imouto sae Ireba Ii first hit stores in March 2015, under Shogakukan’s imprint. The book was written by Hirasaka, and features illustrations by Kantoku (The “Hentai” Prince and the Stony Cat.).

A manga adaptation of the series, titled Imouto Sae Ireba Ii. @comic, launched in Monthly Sunday GX magazine. The series, which is being produced by Idu, spans two collected volumes. A third book will hit retailers on May 19.

A manga spinoff, titled Imouto Sareba Ii. Gaiden Imouto ni Saenareba Ii!, is being produced by Kobashiko. The title launched in Square Enix’s Gangan Joker magazine in October 2016.
