There was a moment of silence. Izuku could only stare at his father as he held out a strand of hair.'' what?'' Izuku was told so much. Inko plucked the hair out of Toshinori's hand.'' Izuku. Put this into your inventory.'' Izuku listened.'' Look at what it says.'' Izuku nodded. Clicking on it he was given the option of use, Information, Drop. This was the first time he had seen the use option, But that didn't matter right now. He clicked on Information.

============
Toshinori's hair strand.
A single strand of the blond locks of Toshinori Yagi, More commonly known as the Hero all Might, On the open market this baby could be sold for nearly 70.000 yen Or 500 Dollars. But within the strand like a secret that is worth more than trillions of dollars. The Secret of One For All... More.
=============

'' Really, 500 bucks for his unwashed nasty hair.'' Cathleen said as Izuku repeated what he read.'' He is famous and people are weird.'' Chiyo said from her chair.'' Izuku click on more, That will hopefully tell you exactly what it is.'' Izuku nodded, trusting his mother.

============

The quirk One For All. A power that was created more than 200 years ago. During the time of the quirk wars. A young man by the name of Yoichi Shigiraki. The twin brother of Ankoku Shigiraki. Ankoku quickly started using the Moniker of his quirk. All For One. Both believed the younger brother to be quirkless, His weak frail body embodying that of what AFO already believed quirkless to be. To force his flesh into servitude, He forced a quirk upon him, An energy-stockpiling quirk. Yet Yoichi had a quirk. His brother had the powers to take and give quirks of others, Yet Yoichi had the quirk to give his own quirk. Which fused with The energy stockpile. 

Yoichi became the first user of the quirk that would be known as One for All. Yoichi fled, Joining the rebellion, The first heroes. Those who wanted to fight All For One's rule. Those who would not sit down without a fight. They held countless battles. Hundreds of lives were lost, Including Yoichi. Yet before his final moments he passed it on to Kudo, THe leader of the resistance. Bestowed with the quirk that was One for All, His quirk Gearshifted Fused within it.

Gearshift allows the user to change the speed at which things Accelerate through space. Even going so far as to ignore the laws of inertia. Yet even with this, it was too little against AFO. Kudo himself also fell into battle. Just like Yoichi and many after him, Dying at the hands of All for One. Yet One for All still remained in the hands of heroes. It was given to Bruce. A high-ranking member of the Resistance His quirk joined the mix. Fa Jin. A perfect mix for the energy stockpile quirk that was forced upon Yoichi. The user could build up Kinetic energy, giving the user an explosive burst of power and speed.

Yet All For One remained undefeated. Soon Bruce fell victim to the power that was the Evil lord of the underworld, The fourth user Hikage Shinomori was a viliant and noble man who was determined to defeat AFO, Yet he understood All For One was still in his prime, He was undefeatable with his current capabilities. Even his own quirk of danger sense, giving the user to detect any potential threats in the surrounding area. Making the user if fast enough nearly untouchable. So he fled into the woods.

In a society where there was chaos and death on the streets. He chose to cultivate One For All. Training in the woods. For nearly 20 years, Hikage lived like a hermit, hiding within the woods, Yet at 40, his body started to deteriorate, showing signs of old age. Hikage sought out the next user, Daigoro Banjo before trying his hand at defeating All for one, Yet even after so long, He failed at giving the overlord long-lasting injuries, But now the quirk for the first time was given to a real Hero. Lariet, Or Banjo. A new quirk fused in. The quirk of Black whip. The users were given the ability to produce black energy tendrils from any part of their body and control them at will. This gave the quirk more mobility than ever before.
