Surely when the time comes we will see an orgy with Violet and Hinari together, the same with Marin and Yui, although these two surely with Akane and Juvia.
And surely at the end of the game all the girls will be in a big orgy in the final NTR.
The truth is that I am also waiting very patiently for the appearance of the goblins, I want to see more scenes with them and especially more events in military camps that I like that kind of scene.
I think we are currently entering a point where an update could easily take up to 2 months to arrive. In fact this last update took 2 months to come out; even if it is a bit longer wait, the truth is that I would gladly wait if it means that Inatari will have more time to polish details and especially his drawing style.
For my part what I'm most looking forward to seeing in Juvia's corruption of Akane. I can't wait for the moment where we get to the central gate or the camp where the soldiers' tents are and see Akane and Juvia (and maybe another girl) having sex.
