After defeating the dragon and rescuing the village, Nami formed a pirate group and began sailing on the sea as the captain. And when they reached the sea, they discovered that the most terrifying thing was the unknown and insignificant vice-captain standing behind Nami! The false captain: timid, scared, miserly, and beautiful as a flower. The real captain: calm, nonexistent, powerful, and the strongest mate. Hawkeye: "My slashes can't break through his defense?!" Kizaru: "What the hell is that speed! I can't keep up!" Akainu: "His destructive power is actually stronger than mine!!" This novel and its characters are purely fictitious.
