Winning grants rewards, and the crew's strength is higher than before. 4️⃣ The male protagonist transmigrates to the One Piece world and becomes the Going Merry ship's original form. He can complete missions, upgrade his form, and obtain various rewards. He starts by setting sail to Windmill Village to collect travel expenses and can also travel through various dungeons for adventure. 5️⃣ The protagonist transmigrates to the One Piece world and is bound to a cultivation system.

He starts in Silses Town, meets Luffy, and joins the Straw Hat Pirates.
