I'm searching for a manga that's pretty much this:
Hyper Sexy Adventure Z! Petualangan hiper seksi Z! (pic related),
but, in the end, they (couple or group) weren't really stranded, only in the far side of an island where there's city. I don't remember if it was also ecchi/hentai as I'm afraid this is just a "Mandela effect".

Oh, this is THE page that is off for me.

And I found it myself, it was pretty much the same thing minus the Mahou Shoujo and what I said earlier, thanks for the backup people, mods/janitors, if you don't find this Roundabout amusing, just delete it.
