She's just a big fucking cheater. It's like she gets her own personal reset button in order to improve on anything she wants to do better, even to the detriment of others. For example, she did not deserve first place in fifth grade, but used her superpower to unfairly snatch away first place from the rightful winner.
Similarly, she deserved to get a 98 on her test, but cheated and got 100, thanks to her cheat power.
She doesn't want a closet; she wants a maid. A closet can store your clothing but can't put it on for you.
I'll still read this because not every story has to have likable characters to be interesting, just like how not every story has a happy ending.
