One Piece: All For One

I transmigrated into the world of One Piece and gained All For One’s ability from My Hero Academia.

There’s also a bizarre System that only unlocks Quirks after I complete its assigned missions.

One day, a man arrived at Mary Geoise and freed all the slaves.

Laughing, he said, "It’s all right now! Wondering why? Because I am here!"

At the Paramount War, a man blocked Aokiji with flames from his left hand and Akainu with an iceberg from his right.

Kizaru was wrapped in bandages and rendered immobile.

Blackbeard’s face was blown up in an explosion.

The man behind it all watched happily, because everything was his handiwork.
