Being from a family of Pro heroes, great things were expected of Emiri Koyama. But when she was a little girl, those expectations were almost diminished when it was learned she would spend her life bedridden due to a rare illness. It was described as a miracle when she made a recovery at the age of 12. Almost immediately, she was put on the track to become a hero. Emiri followed along with the orders she was given as she grew up, knowing that she had big plans of her own. "People should not be defined by their quirks, but instead by how they use them. And I'm going to make the the world realize that, no matter what I have to do."
