Gyakuten Parallel World Kanojo [English], by Chimichanga

Now, that’s an original story type. I never imagined I’d see something like that.
First, the male hero is visited by another version of him from a parallel universe. A mirror universe. He is a man, his other him is a woman. He is a scumbag, she is altruistic. He gets more manipulative, she becomes unable to protest any order.
So, in this context, it might have been a bad idea to visit scumbag-him to tell he should stop being such an asshole or obedient-altruistic-she will become unable to refuse any order.
… if you see what I mean :3

They have one common point, though, they both love sex. You can mirror universes all you want, some things never change
The drawings are nice, wandering on the ahegao side so I lost some enthusiasm around the end.
Still, for the parallel mirror universe idea, HUGE PROPS, I think it’s worth a read
