Souryo to Majiwaru Shikiyoku no Yoru ni... is an erotic josei anime based on the manga of the same name. It aired from April 3, 2017 to June 19, 2017. Due to its sexually explicit content (and the possibility of using said content to promote home video sales), three different versions of the series were produced: an "all ages" version, an "R-15" version, and an "R-18" version.
All ages version
The "all ages" version is the version that was broadcast on public television in Japan. Heavy cuts were made to scenes of sexual activity and nudity throughout the anime. Some additional scenes were added focused on comedy/the priest's backstory in order to make up for lost time. While the dialogue at times references the characters having "done it", nothing is ever seen.
The R-15 version was broadcast on premium channel AT-X in Japan. The AT-X version leaves some partial nudity and the sex scenes intact; however, the majority of the screen is often blocked with objects/logos during sexually explicit scenes. (For example, you can see Mio's breasts and her expression in one scene in which Kujo gives her oral sex, but anything below her waist, including Kujo's head, is obscured.)
How to obtain the uncensored version
The uncensored version is available on home video in Japan and via adult streaming websites.
