Old Soul || A BNHA story

Prologue

Enjoy :]

"Master!" The muscular blond man cried out, the lifeless body of his mentor, Nana Shimura falling to the ground. A deep evil chuckle escaped the mouth of the man standing above the woman, fresh red blood on his hands and splattered on the black skull mask. "To..Toshi... run.." the black haired woman spoke with her last breath, the blond man looked for a way to escape but quickly shook it off. The rage that made his blood boil made him stay, he wanted revenge for his master. "All For One!" He yelled out the name of his nemesis, tears streaming down his face, the smile that his master always wanted him to wear proudly now replaced by a look of pure rage.

"Oh didn't you hear her, Toshi. Run away from your problems. Run away from me.. after all, you could never defeat me" The man now dubbed All For One mocked him. "I will.. whatever it takes!" 'Toshi' yelled out, the piercing blue eyes full of determination. "Whatever it takes..." the masked man repeated as he readied himself for the coming fight.

The two stared at eachother, waiting for the other to make the first move. But 'Toshi' had enough and bolted forwards, ramming his fist into the black mask but in return he got punched into the stomach, the spear like bones that were coming out of All For One's right arm piercing the blond's skin. "As I said, you could never defeat me, All Might" he told him as he turned his arm, making the now dubbed All Might grit his teeth. "I am not dead yet!" the hero yelled out as he threw another punch, pushing his nemesis back a bit. But All For One quickly stepped forward again, throwing punch after punch at the hero, but All Might kept up with him. The two were just trading blow after blow, yellow lightning flickered around All Might's arm as he threw a 'United States of Smash' at All For One's face.

The mask shattered like porcelain under the fist, black shards flying threw the air as All For One flew into the debris that used to be his headquarters. "Whatever it takes.. Plus Ultra!" All Might yelled as he stormed forwards, his fist about to collide with the man once again but he stopped. The face under the mask looked so regretful and scared, "You can not fool me, All For One.. This will end here and now!" and with that, All Might slammed his fist into the white haired man's head.

The once white hair was suddenly almost completely red and thick red blood was dripping from All Might's fists as he fell to his knees. His head instantly shot back up when he heard a whimper come from All For One. "I... I will return... In... In another life.... even you won't be able to stop me, Toshi..." A red glow appeared on his hands, like mist slowly covering the entire body in a thin layer. "No.. No you will never return!" with that, All Might went for the killing blow but it didn't seem to end the process, instead the mist slowly turned to an emerald green. A glowing golden rune appeared on All For One's forehead, before the mist faded together with the rune, leaving only All Might kneeling in front of the bloody pulp that was his nemesis.

A young man with black hair, in a police uniform stepped up to the blond man laying a hand on the hero's shoulder. "He said that he'll return.." All Might said softly as he looked at the white hair on his hand that had been stained by blood. The officer let out a sigh, "Then we'll arrest him before he can cause anybody any harm. Now, come on" the man said as he helped his friend up and the police arrived.

All Might watched as the lifeless body of his mentor was carried away, his hand clenched to a fist. "I will find you and bring you to justice, once and for all, you'll never hurt anybody ever again, All For One!"

Cheers!
