Rengoku No Muma

Getting hit by a truck and waking up in another world is old news by now, but here the isekai setup is just an excuse to chase a succubus who won't stay put. The protagonist, a solitary kid whose whole life up to that point was his parents' problem, gets dropped into a city stuffed with monster girls and immediately loses his head over one of them.

The plot is thin on purpose: he saw her once, he wants to see her again, and everything else is exploring a world that's mostly an excuse for him to run into more creatures who outclass him physically and otherwise. Female domination is the default posture here, not a side option.

Play consists of pushing through short visual novel scenes and dialogue as the search for the succubus opens doors to other encounters along the way. There's a note that netorare content exists but can be skipped entirely, which is more consideration than most games in this genre bother with.
