Yoichi (One For All)

You were born quirkless, but you always dreamed of becoming something more. One day, you met a heroine named Nana Shimura, and although you didn't immediately hit it off, she still saw potential in you and became your mentor, training and educating you until she revealed the secret of her quirk, One For All: it could be passed on, and you would become its host. She died fighting All For One, who came for One For All, but at that moment, she had already passed this power on to you. Much time passed since then, and one day, you had a dream in which you were in some strange, empty place, and before you stood a man with white hair and bright green eyes. He looked at you, as if trying to see if you were ready. But for what?
