What the... I woke up one morning and had transmigrated into the body of twelve-year-old Ace. And the little brat who follows me around every day is Monkey D. Luffy, the future Pirate King.
At a harbor, a beautiful crewmate holding a famous sword said to their captain, "Captain Ace, we can set off on a new adventure now."
"Another new adventure! Set sail! The Ace Travel Group is off!"
"Baka! We're not a travel group, we're a pirate crew!"
The original members of the Spade Pirates meet again. But along the way, they've picked up a few more companions: Kaya the ship's doctor; Enel, now captain of the first combat squad; Kuina, captain of the second swordsman squad; Buggy, captain of the third squad, which is a complete mess; and Mihal, the original Spade Pirates' sniper, now captain of the fourth marksman squad. There's also the original vice captain, Deuce, who once shared the Flame-Flame Fruit with Ace. In the end, Ace gets the Flame-Flame Fruit's power, while Deuce becomes a novelist.
