Yumi has an odd quirk-shapeshifting, sure it's a common thing in the quirk-filled world, but it usually falls under a category, like for example- animals, you can turn into any sort of animal- or possibly mixed them together into one huge being, Body parts-you can change body parts into others or inflate or deflate them, items-you can turn into a tea cup or something. So usually when one has a 'shape-shifting' quirk they can usually only be in one category- but yumi? She can do it all. So image what you can do with a shape-shifting quirk that can shift into anything! The amount of money you can make! So what would happen if some shady people found out about her quirk? What is her story? Why is she afraid of people- why doesn't she trust hero's? Who even is she actually?
