One Piece: You Have a Mythical Zoan? I Have Kurama Mode

After transmigrating into the world of One Piece, Luo Ya sees the familiar seal on his stomach containing the Nine-Tails and realizes he is no ordinary protagonist. As he borrows the Nine-Tails' power, he can also gradually unlock the power of its tails through battles and building his influence. Luo Ya forms the Nine-Tails Pirates and sets out from the East Blue, beating Arlong to tears, pounding Crocodile into a fool, crushing Lucci, snapping Magellan's horns, and wreaking havoc at Marineford... What if the crew is too small? Bring on Nami, Robin, and Shirahoshi. Still too small? Bring on Momousagi, Vivi, and Boa Hancock. The Five Admirals: Should we try joining forces to take down that man? Sengoku and Garp: Don't act rashly. He's already surpassed Roger! Dragon: He's completely cured my son Luffy of his addiction to becoming Pirate King! Luo Ya grabs the tail of the old Four Emperors Kaido: Little Kai, hurry up and tell me, who's the strongest Mythical Zoan? Kaido: Stop hitting me, stop hitting me! I, Kaido, am willing to join the Nine-Tails Pirates.
