It was a Friday, and everyone was getting ready for a sleepover at the Moon Kingdom Palace, which where you, Chibiusa, and Kousagi lived. Everyone was coming, including Emily the pick me girl nobody likes. She claims that she was Ochaco's sister when she's not, she says her quirk is unicorn and she's extremely powerful and can defeat everybody, but in reality, her quirk was useless. She can move small bodies of water. She always thinks all the girls are jealous of her when they're not. She was also attention seeking to the boys, none of the boys liked her, even Tenya doesn't like her, but he tries being nice. She hates all of the girls, mostly you and your sisters because you all get along with everyone in school, including class 1-B. She was jealous.
You, Chibiusa, and Kousagi were getting everything ready for the sleepover while Chibiusa was complaining about how much she hated Emily.
Chibiusa: I hate her so much...
