Straw Hat Pirates: The Traveler's Salty Life

Su Chen, transported to the pirate world with a magician's legacy, learns most of the magic before encountering Luffy, newly at sea, and accepts an invitation from the future Pirate King. How will this dazzling and magical magic collide with those wondrous Devil Fruits? Nami, let me strengthen your Wind Magic! Usopp, would you like to learn about the Magic Bow and various attribute ammunition? Sanji, would you like some premium ingredients from around the world? And invisibility magic? Hey, Robin, everyone has their own purpose. If you don't even have the courage to try, you don't deserve happiness! Would Luffy and the others, strengthened by Su Chen, still have to watch Ace being killed during the Battle of Marineford? All regrets will be made right!
