A long time ago, the villain, All For One, a man with a Quirk that allows him to steal other Quirks and give them away, forcibly gave his seemingly Quirkless younger brother a Quirk that allowed him to stockpile power within his body. However, what they didn’t realise is that the younger brother already had a Quirk with no other power than that it could be transferred to another person. The transference Quirk and the power stockpiling Quirk merged into one and from then on became One For All.
The power of One For All can be a huge burden for those who bear it but All Might believed that Deku could handle it, which is all the more reason to grab yourself these My Hero Academia One For All Shoes now !
