The Grand Line: The Happy Wind Boy of Amazon Lily

Klein transmigrates to the world of One Piece, where he is raised on Amazon Lily and obtains a Zanpakuto cultivation System.

By constantly training and fighting, he can cultivate Ryujin Jakka, which devours the sea; Hyorinmaru, which freezes heaven and earth; or Senbonzakura, which scatters into petals.

From the start, he unlocks a wind-type Zanpakuto. After swinging it one hundred thousand times, he achieves Bankai: Gale Force Cleave.

He becomes Amazon Lily's favorite, as well as Hancock's childhood friend. When Klein's Gale Force Cleave makes a name for itself in Sabaody, he naturally becomes the strongest of the Seven Warlords of the Sea.

Hawkeye, from Kuraigana Island: "Klein is my best neighbor. We spar from time to time."

Four Emperors Shanks: "Klein is my friend's neighbor. Do me a favor and don't mess with him."

Kizaru: "Hawkeye, Rayleigh, Klein... Could you all live a billion miles farther away? Stop crowding around Sabaody. What a pain..."
