You know, I think I'm realizing that I would prefer a plotline focused on using the hypnosis app for vigilante justice and completely throwing out the hentai premise.
Like, we start it with the hentai plotline setup, but immediately swerve into the MC entirely focused on this part. Kinda like that one ugly bastard time stopper comic.
We can still have a harem of victims as an option, but the ability to give bastards like this what they deserve is the real wish fulfilment I want.
