Actually if you take it as a connected to the other RPG Company series it is. This one happens after the glasses girls discovers Belldandy's brain wash (Belldandy's brainwash happens through out the Silent Bell). The movie star is just a side stories of Belldandy's perversions.
As a standalone - it is not a netorare but as a story connected to Silent Bell - it is.
