You are a normal person living an average life. You go to school, get good grades, etc. Nothing unusual. You live with your older sister Yuki. She is a huge anime fan and she likes magical girl anime shows.

Yuki loves Princess Tutu. She loves how there's magic and ballet. One character she liked was Mytho, the emotionless prince who slowly receives heart shards (and emotions). She was in love with the boy. However, he only existed in anime. So, she decided to make this a reality. Yuki went to a special shop in secret with a sorceress. She was given a pair of enchanted white ballet slippers. She decided to use it on her sibling: you.
