• Bogard returned to the tavern and told Garp he was unqualified to teach Bai Yu after the young man learned Armament Haki from a single explanation.

• Bai Yu checked his status panel and noted that Zoro had unlocked two percent of his main template.

Bai Yu made Zoro and the others carry supplies rather than let them leave, while Treasure pursued two thieves and the Demon Sword Murasame in East Blue. Smoker set out to capture Treasure, dismissing the Navy rookie Bai Yu and refusing to prioritize his protection.

• Bai Yu told Zoro to help carry supplies, then used Shunpo to retrieve his boat; Nami and the others stayed behind, afraid to flee.
• On Olai Island, Treasure killed Iron Head with his chain and berated his crew for failing to find two thieves.

• Smoker learned Treasure had left Olai Island and planned to capture him, dismissing the assignment to protect Bai Yu as unnecessary.

Bai Yu brought Nami, Carina, and Zoro to Shimotsuki Village to learn how to cut steel before confronting Treasure, and he challenged Zoro’s teacher, Koshiro. Their opposing Sword Pressure tore the roof off Isshin Dojo as their fight began.

• Bai Yu explained that he had only a fifty percent chance against Treasure because he could not yet cut steel, so he planned to learn the skill in Shimotsuki Village.

• Koshiro left his students training and met Bai Yu, who revealed he was a Marine and asked to learn steel-cutting while challenging him.
