The fiery heart of a phoenix (Male reader x fem oc)

you are the son of the former number one hero, whitebeard which makes you and many of your siblings pretty big deals. Everything was awesome...until the day you got your quirk. It was that very same day you got quirk that All for one and All might fought with villains under All for one's pay roll running rampant. It was that same day that you lost your mother to one of those said villains. Now you're 15 and things have gotten better and worse at the same time. Your father has gotten sick with no amount of medicine or quirk being able to cure him. It doesn't look like he has much time left and while you don't want to leave his side, your father as well as your siblings urge you to follow your dream and become the hero that saves everyone and a symbol...of hope
