Everyone has their own kinks. I don't think the video was "bad", but I was a little puzzled.
Mary is the mascot of ARG, and that has never changed. However, the developer/lead animator has been using Hina as an avatar on most of her Social Media pages for ... idk, almost 4 years now?
I expected the first Hina video to be balls-to-the-wall-batshit-insane on sexual quality and story progression. I suppose (have asked many times in the past either on here/twitter/patreon) why Hina means so much to ARG when compared to Mary, never got a solid answer. This video didn't provide anything either.
But! Always glad for new content.
