Vongola transmigrates to the world of One Piece, becoming a member of the Beasts Pirates. He decides to stay on Onigashima and strive to become the fourth-ranked member of the Beasts Pirates. Although the members of the Beasts Pirates are skilled at all sorts of antics—the "Artistic Disaster" loves clubbing, the "Face Disaster" is all about abstract art, and the "Foolish Disaster" relies on the Ship King—it's common knowledge that Kaido is definitely the best teacher in the One Piece world. He quickly mastered Ryuo, Hakimasu, and Enchanted Sakura. "You're the worst class I've ever taught!" Fortunately, Vongola starts by fusing with the legendary Pokémon Tyranitar, becoming the embodiment of the will of the earth. What's so great about being the Pirate King? My idol is the Mountain Bandit King, Higuma!! I'm going to be the Mountain Bandit King! When Akainu's magma is shattered by the Dark Pulse, and Aokiji's Ice Age melts away under the Primal Force, the whole world finally feels the fear of being dominated by the Desert Tyrant! Kaido: I am the strongest creature! What is that 10,000-meter-tall Emerald Beast?!

What's it like to be a prince? Excellent looks, extraordinary talent, absolute power... Great, this must be my script for conquering the world! Hehe, I'm going to dominate the world! But when Faust picked up his dance partner's lost shoe, he suddenly realized... This is still a fairy tale world! But can anyone tell me... what does it mean to bring winter with beauty and give madness with song like "Snow White"? What does it mean to be a blood moon's generation of servants, the hunter "Little Red Riding Hood" who fights the Ancients? What does it mean to be the "Little Mermaid" who leads the deep blue flock and judges all living beings on land? .................. This fairy tale world seems too extreme. Dude, with these world-destroying monsters around, how am I supposed to dominate the world?! (Annoyed)
