Dimension Hopping For Dummies With Yaomomo

In which Momo Yaoyorozu utterly panics when she realizes that she's a side character in an anime... fanfiction. The fact that she's a pseudo minor villain with a tragic backstory adds more salt to the wound. But, fortunately, luck is on her side, or is it?

Or, alternatively, in which Momo dimension hops a few times, lives in various worlds, gains a new quirk, goes back to the original anime ( or does she? ) and douses glacial cold water on the plans of the villains by being way too overpowered. Not particularly in that order.
