Ch. 581I Killed Him
Here is a concise summary of the provided chapter ("I Killed Him"):
Key Plot Points & Events
- William deliberately leaves Luffy to fight Kaido of the Beasts alone, despite Gaimon's protests.
- Nami explains that no one can stop Luffy because Kaido directly provoked him (by destroying his food).
- Usopp panics about the aftermath if Luffy loses, prompting William to hint that he has a plan to defeat Kaido (potentially involving Gecko Moria's ability or a pre-arranged scheme), but they need time to prepare.
- Nojiko uses her advanced Observation Haki to detect the approach of Kozuki Momonosuke and his samurai army.
- Momonosuke, now the new daimyo, attempts to lead a charge against Kaido to avenge his father, Oden, but faints from sheer terror mid-stride.
- Zoro finally appears on the battlefield and attacks the samurai with a "Three-Sword Style: Tornado" to stop them from interfering with Luffy's duel, threatening to kill anyone who interrupts his captain.
- Kaido responds to the surrounding army by unleashing a powerful whirlwind kick that sends Zoro, Momonosuke, and the samurai flying.
Character Developments
- William: Remains a strategic tactician, intentionally staying out of the fight to devise a clever counter-plan rather than relying on brute force.
- Nami: Demonstrates her deep understanding of Luffy's personality, justifying his rage and the need to let him fight alone.
- Nojiko: Showcases her highly specialized Observation Haki, which allows her to perceive events across long distances.
- Kozuki Momonosuke: Shows a clear character flaw—he tries to project bravery as a new daimyo but is fundamentally a coward, fainting at the sight of real danger.
- Zoro: Reinforces his role as the fiercely loyal right hand of Luffy, prioritizing the sanctity of his captain's duel above all else, even attacking allied samurai.
Significant Themes
- The Sanctity of a One-on-One Duel: The chapter emphasizes that a captain's duel is inviolable; interfering is a taboo punishable by Luffy's wrath and Zoro's blade.
- Strategy vs. Brute Force: Contrasts William's calculated waiting and schematic planning against Luffy's direct, emotional, and reckless combat style.
- Leadership and Cowardice: Explores the divide between assumed bravery and actual courage, using Momonosuke's failure as a leader-in-crisis.
Character Interactions
- Gaimon, William, and Nami: Gaimon questions William's decision; William is dismissive ("Who knows?"), while Nami confidently affirms Luffy's impulsive nature.
- Usopp and William: Usopp expresses fear of Kaido; William teases a viable plan, giving the group cautious hope.
- Momonosuke and Kin'emon/Brook: Kin'emon and Brook realize the danger as Momonosuke is carried into battle, but are unable to stop him because he has fainted.
- Zoro and the Samurai: Zoro violently redirects the samurai's charge, asserting his dominance and protecting Luffy's fight space.
