I'm in the World of One Piece: My Little Sister Is Robin, and I Have Her Protection!

Wayne was born into this world as Robin's twin older brother, and received blessings from the myriad worlds:

The Blessing of Strength at Birth: A naturally powerful body, and a new blessing ability every year.

After going out to sea, Wayne's blessings became even more terrifying:

Blessing of the Night Sky: His power increases at night. Blessing of the Sun: His power is never depleted beneath the sun. Blessing of Healing: Any injury that isn't fatal is completely healed instantly... Immortality, the darling of the myriad worlds, and other blessings that grew increasingly absurd.

Eight-year-old Wayne:

"I'm still not strong enough."

Twelve-year-old Wayne:

"I will become the pinnacle of the New World."

Eighteen-year-old Wayne:

"I'll do whatever the hell I want!"

Before you stands:

The gravedigger of the old order, the sole ruler of the sea, the true god who stands above the heavens!

Now,

offer your token of loyalty to the supreme sovereign!
