This is a story about dreams, hope and friendship. Feiyu D. Ling holds the ancestral Feiyu Blade, breaks away from the shackles of the ancient martial arts of the West Sea island country, and sets sail to sea with the dream of becoming the world's greatest swordsman. The sword light cuts through the waves, and the various strange devil fruit abilities complement each other. The partners protect and support each other. Feiyu D. Ling, who once believed that spiritual practice could only be carried out alone, learned from the warmth of being with him along the way that chasing dreams never needs to be carried out alone. The road ahead hides countless top swordsmen, many dangers, and secrets buried in the world. A crimson feather blade, and a group of close companions, traveling thousands of miles across the sea in the name of pirates, keep moving forward towards the destination in their hearts.
