I’m in One Piece, and I’m the Dream-Battling God

Klein transmigrates to the world of pirates and gets the Sleep God System from the start. He unlocks character templates, and sleeping speeds up his progress toward unlocking them: Yamamoto Genryusai Shigekuni, Kageyama Shigeo...

This is the end of the Rocks era. To take part in the God Valley Incident, Klein, a former Marine ensign, joins the Rocks Pirates.

Rocks: Do you want to rule the world?

Klein smiles faintly.

"No. I just want to drag those Celestial Dragons down from their lofty heights."

Golden Lion: Next time, next time I'll definitely beat you!

BIG MOM: Klein, I want to eat braised lion's head.

Sengoku: Klein actually learned his two-color Haki at the Marines' headquarters academy!
