Hey there, this is a mainly focusing on Shanks, though many of the One Piece characters like the Strawhats will be in there. I've seen stories of Shanks before as the main character, but even then it'll still be with someone else in the mix, so I wanted to give this a try. Also this will be a cross over with Boku no Hero Acedemia and i just wanted to see what direction his story will take. And so this was the mess that wawas created, enjoy. I dont own One Piece or Bnha, they belong to their respective owners.

Shanks walked around the busy streets, pulling down his black baseball cap to hide his bright red hair. He tilted his head down, making him look highly suspicious if not for the bright kill-me-yellow shirt and floral patterned pants he was wearing. He had switched out of his captain's cloak, straw hat and white button up, all of which were to big and dirtied anyway, in favour of his stolen goods to remain unrecognisable to the public. He had enough experience to be a professional at being undercover. Though he may just be one of the most, if not the most flamboyant pirate, he had a... tough childhood to say the least.

Sneaking around into another dark alley, Shanks sighed, wondering how all this happened to begin with.

Flashback*

Shanks held back the water that was threatening to spill over his eyes. Around him lay thousands of people, splattered with liquid red roses that bloomed across the floor like a bouquet of deadly poison. As blurred eyes scanned across the battlefield, he could recognise so many who have fallen. So, so many. Allies, comrades, crew, friends, family, lover. All so different, yet all bound by a single word. Nakama. They were all his Nakama. So why? Why had he failed them all? Why did everyone die when he had survived.

Shanks sank to the ground. Around him were a few sole survivors, all of which were from the other side of this god damned war. He could hold it in anymore. Salty tears dripped down his face, some landing in his mouth, reminding him of the sea. The wide sea that was his home, now only brings up painful memories of those he once had with him. Lifting his head, he opened his mouth and screamed. It was a pain filled sound, filled with his sorrow, guilt and hate, fused with an insanely powerful haki blast, stronger than any others he had ever let out. Everyone was dead now. That finale yell to the heavens above shook the very core of their world, making it tremble and quake.

He surveyed the crimson battle field, pirates from every sea, revolutionaries from every part of the world, marines from every head quarters, all dyed in the same colour, bathed in the same life liquid. Among them were the second pirate king, a hawk-eyed man, the most beautiful woman and many, many more. Some marines had seen the sheer idiocy in their actions to purge every pirate from the planet and had joined their side. Some include, Vice Admiral Coby, Vice Admiral Garp and former Admiral Aokiji aka Kuzan. People like Blackbeard had no sides and died in the middle of the cross fire. Yet, it was no use. A good half of the world's population have been decimated, with the last survivor on the brink of death.

Akagami stood back onto his shaky feet, taking a few steps forward. Each step was agonisingly slow and it took all his will not to scream out in pain. He stumbled his way through the piles of dead corpses, making his way through the sticky blood, eyes focused on one thing. If he was going to go out last, he will restore the beloved hat passed down from the generations to its former glory. He stood in front of the last owner of the hat. Bending down, he plucked it of from where it had laid askew on his surrogate son's head. The hat had been battered through the generations, each holder destined for great things, now soaked through with crimson liquid. Shanks used what little clean part of his captain's cloak to wipe off any of the scarlet liquid. He used his nails to scratch off any of the dirt and dried blood on the hat. Plucking off some of his once beautiful bright red hair, he tried as best as he could to knot back some of the holes from bullet shots. Though he could do nothing about the burn marks.

As he took one last look at the somewhat repaired mugiwara, he couldn't help but voice out his final thoughts, "I'm tired."

Then, darkness.
