Are You Crazy? You Want Me to Become an Admiral for Defeating Rocks?

He transmigrates into the world of One Piece.

Before the Battle of God Valley.

Ryder obtains the Mythical Zoan Bat-Bat Fruit, becoming a vampire-type ability user with an incredibly powerful body and regenerative abilities.

From then on, a terrifying Vampire King appears on the seas.

Rocks: "If it weren't for Ryder, I would have become King of the World long ago!"

Edward Newgate: "My Tremor-Tremor Fruit is actually useless against him?!"

Garp: "Ryder was the one who defeated Rocks. He absolutely deserves to be called a 'Marine Hero'!"

Sengoku: "A man who developed his Devil Fruit to the very limit!"

Staff Officer Tsuru: "Ryder, Sengoku and Garp say you can even absorb physical techniques and Haki. Is that true?"

Ryder gives a wicked smile. "How about... finding somewhere... and trying it out, Vice Admiral Tsuru?"
