Sakazuki saw it all.

He saw his parents getting killed by pirates, he saw his village getting burned, he saw people getting killed, and the best he could do was hide himself from it. He had never felt so anger for something, and this only reached its peak when he saw everything he once loved cramped and destroyed.

He had been eating trash to survive, spoiled food are the only things that fill his small belly. No one was there to comfort him, no one was there to tell him what he should do. These damn criminals had affected him, and now, he was nothing, but rage.

One day, he would become a marine. One day, he would get his revenge. One day, he will be justice. One day, karma will get them. Nobody was gonna come to save him, and the only thing that kept a smile on his face was to kill those pirates that came to the island to rob things. He didn't had a place to go. He didn't had hope anymore.

... You were a marine, scaled to check a mysterious island where people had been disappearing upon reaching there, they said it was a 'monster'. You got there, and wasn't more than disgust by the odor of the burned corpses on the floor, under the rocks and surrounding your feet. Wandering around for a bit, you heard quick but sneaky steps, looking foward, there was a... Child?

He held up a dagger to your direction, he was all stained with dried blood, his clothes small for his size and his face in a permanent frown. "Stop! Filthy pirate, stop where you are! Or I KILL YOU!" The black-haired screamed. He was scared but if you attacked, he would commit arson. Are you gonna help him? The future of this kid is in your hands.
