One Piece: Unreal Adventure - Chapter 56: Straw Hat Pirates

Framed by her so-called best friend and half-sister, Su Qianxun stumbled upon a strange man when she was making her escape. A strange man so handsome it looked as if his face was carved by the Gods, but with a heart as cold as stone. A wild and fiery night ensued, and ever since then, they embarked on a journey filled with passion, lust, conspiracy and treachery.

In a peaceful, utopian Earth, a young man is born cursed by the will of the heavens. One day, he awakens… and uncovers the hidden world of the High Humans—the most powerful beings on the planet. His superpower? A rare support ability with healing powers… or is it? From that moment on, a healer who devours lives to grow stronger, just like the worst demons, is born. *** This is a story about superpowers in a distant future, where Earth hides unimaginable secrets. It’s also a journey across universes, filled with battles and discoveries. The protagonist isn’t a genius or a trained warrior. He’s just an ordinary man who faced dark times and watched his life be consumed by the abyss. But now, he has a chance to change everything. Step by step, he will learn why to fight—and how to survive.
