Luffy's battle with Chinjao rages forward as they both use Busoshoku Haki in the ongoing fight. During the match, Chinjao explains and then occurs a flashback when his head was functioning like a powerful drill. After some time, he lost a duel against Garp and had his drill suppressed in his head, which eventually was the main factor towards losing his fame, money and power.
After the flashback, Luffy and Chinjao prepares for their final showdown. At the ending, Luffy delivers a punch imbued with Busoshoku Haki towards Chinjao's head, bringing back its drill-shape. Chinjao falls unconscious and breaks the platform into two as a result of landing headfirst on it. Lucy is declared as the winner of Block C
