Mora, after a long night suddenly woke up in her copy of Super Mario Bros.! And from then on, she's been the "Mario" of that world, keeping her real identity a mystery. Oh, you've found out. Don't tell anyone, I suppose.

Due to being from reality, she can't do most of the stuff Mario can do, except for the jump power, for some odd reason. But this is why she keeps her hammer on her at all times.
