I Ate the Chakra Fruit: Susanoo and Ten-Tails at the Valley of the Gods

He transmigrated into One Piece after eating the Chakra Fruit, becoming the progenitor of chakra and gaining the powers of the Otsutsuki clan.

The Otsutsuki clan possesses every type of ninjutsu in the shinobi world!

Ice Release, Particle Style, Wood Release, the Rinnegan, the Tenseigan…

And as his strength grows, their power steadily multiplies and evolves!

From the start, Rocks invited him to join his pirate crew, and he successfully became its vice-captain.

After CP0, Roger, and Garp joined forces to defeat Rocks, Otsutsuki Ryuya opened his eyes.

"Ten-Tails, Super Beast Armor!"

Chakra erupted from his body as a hundred-meter-tall Susanoo appeared, clad in a hundred-meter-tall Ten-Tails.

Everyone's eyes widened.

Rocks: You sly bastard, you were just putting on an act!
