A Zanpakutō, Ruling the Grand Route

Traveling through the world of pirates, you get the Zanpakutō evolution system, which allows you to unlock various types of Zanpakutō. From now on, Klein's Zanpakutou can become the king of everything in the sea. It can become the Ryuken Wakahu that engulfs the sea, the Hyōrinmaru that seals the world in ice, and the scattered Senbonzakura. After unlocking the Zanpakutō forms, he became the undisputed number one swordsman in the world. At the beginning, he was raised by Amazon Lily Kingdom. So he became the favorite of the Nine Snake Island group and Hancock's childhood sweetheart. Hawkeye of Kraygana Island: "Kleon, my best neighbor, I still spar with him occasionally." Yonko Shanks: "Kleon, my friend's neighbor, give me some respect and don't mess with him." Klein: "Nine Snake Island is protected by me. Anyone who offends me will be killed no matter how strong he is. Draw your sword!!!" His sword is called the Fierce Ghost. When the Fierce Ghost roars, there will be no peace in the world!
