The protagonist is another brother besides the three brothers. He was born one month earlier than Luffy. He was picked up by Garp and named Monkey D. Feiyu by Luffy's mother. He grew up with Ace, Sabo, and Luffy and went to sea separately. Feiyu encountered a shipwreck ten days after going out to sea. With his tenacious willpower, he grabbed the ship's plank and floated to an isolated island and obtained the Qi Fruit, a natural fruit. People with abilities can turn into air and can change the speed of air flow to form attack power. They have powerful destructive power and meet their first partner, Kiri, a swordsman. Feiyu doesn't know One Piece, so he is equivalent to a character in it and doesn't know the plot.
