The Kakushigoto Twitter page announced that the anime series will receive a compilation film. The announcement added that the movie can be enjoyed regardless of whether one has watched the series. More details will be announced at a later date.
Funimation describes the show as:
Single father Kakushi Goto has a secret. He’s a top-selling artist of popular erotic manga, but his impressionable young daughter, Hime, can never find out! Now he’s having to bend over backwards just to keep her inquisitive little mind from discovering what he does for a living. A father-daughter tale of love and laughter.
