Summary
Two versions of Mahiro Oyama from different universes switch places. Now they must navigate unfamiliar landscapes and unexpected changes, all while trying to find a way to return home.
As of 6/18/2025, the story has entered it's final saga:
Both Mahiros have faced numerous obstacles during their experiences living each others' lives. Although they have been able to adjust for the most part, they are about to face their most difficult challenges yet in their quest to return home. In less than two days time, Kun Mahiro will be forced to take the same test that Kun Mihari originally took in order to skip ahead straight to college. Failure would mean that her counterpart would forever lose out on an amazing opportunity, but can she really rise to the challenge. And even if she can, what does it mean about the kind of person that she's become thanks to the experiment. Meanwhile, Kun Mihari has become concerned by Chan Mahiro's behavioral backsliding which resembles the old antics of the shut-in brother whose body she's now inhabiting. Just how far is she willing to go in order to prevent history from repeating itself? One thing is clear, things are only going to get even more crazy from here.

Summary
A series of queer Ranma 1/2 fanfics tied to each other spawned out of two oneshots that were originally separate, I want to take a crack at queer ranma fics that are generally more manga based to avoid retreading some already covered ground as far as queer ranma fics go (that first one is mostly focused around the anime but the rest arn't.), and Fueled by the many personal revelations I can thank th simple idea of the curse for. Also passes the time. Hope you enjoy!
