The anime somewhat cleans up some scenes that are in the very much more paedophilic manga where each release also features sexual nude drawings of the minor characters on the last page of each issue, or at least a lot of them.

Edit: Also I remember an interview with the author where he has a doll of the bunny character and sniffs her crotch repeatedly. It’s considered a “joke” in the community, he’s done this repeatedly. Nanachi I think? The nude drawing of her in one issue says “Nanachi won’t let you sniff it. Has a mild scent” in their backpage character profile.
