Elbaf Box Theory: Imu’s 800-Year-Old Counter Revealed

Chapter 1193 of One Piece, titled “Practicing,” has dropped a series of jaw-dropping developments that are sending the fandom into overdrive — and Japanese readers are already piecing together what Oda is setting up for the Elbaf arc’s endgame. If this theory is correct, a mysterious box passed down through generations on Elbaf holds the secret weapon that was always meant to be used the moment Imu returned — and Usopp may be the one destined to unlock it.

The Theory

The stakes here are enormous. Elbaf was defeated by Imu 800 years ago, and yet someone clearly anticipated this exact moment — leaving behind both a letter and a physical tool to be opened only when the time was right. If Biblo’s box is indeed that contingency plan, it reframes the entire Elbaf arc as not just a battle, but the fulfillment of an 800-year-old prophecy. This connects directly to the Nika figure depicted in Elbaf’s murals — holding a sword and shield — and raises the question of whether Luffy, Zoro, or even Usopp is meant to wield what’s inside.

Evidence from the Manga

1. Chapter 1193: Biblo, through Chopper, reveals that a box passed down through generations contains both a “letter” and a “tool,” and that it must be opened NOW — in this exact battlefield. The framing makes it explicit that this is not a coincidence; the box was waiting for this specific moment.
2. Chapter 1193 (Elbaf lore flashback context): It is confirmed that Elbaf was defeated by Imu 800 years ago. Combined with the box being “inherited for hundreds of years,” this directly implies the contents are a remnant of preparation made right after that defeat — a legacy contingency left for the next time Imu arrived.
3. Chapter 1193 (Zoro vs. Sommers): The chapter’s title “Practicing” refers explicitly to Zoro consciously attempting to coat his blade in Conqueror’s Haki — something readers assumed he had already mastered during his King fight in Wano. It turns out coated strikes are landing (Sommers takes damage), but Zoro cannot yet destroy the steel heart. The gap between “reaching” and “breaking” is the key tension.
4. Chapter 1193 (Luffy’s moment of awareness): Just as Gear 5 begins to fade after the massive blow to Imu, a critically wounded Luffy notices something — an “Hm?” moment. This sudden realization, combined with Usopp’s previously mentioned “plan,” suggests Luffy perceives a tactical opening that only Usopp’s scheme can exploit.
5. Elbaf mural (prior chapters): The Nika figure depicted in Elbaf’s ancient murals holds both a sword and a shield — neither of which Luffy currently uses. This detail, long noted by Japanese fans, could point to the box’s “tool” being one of these weapons, potentially meant to be used by someone on Luffy’s crew rather than Luffy himself.

📌 Key Evidence: Biblo’s instruction that the box must be opened “now” — specifically on this battlefield — combined with Elbaf’s confirmed 800-year-old defeat at Imu’s hands, makes it nearly impossible that this is a coincidence. The box is a pre-planned counter to Imu, seeded by someone who knew Imu would return.

📌 Key Evidence: Zoro’s in-battle focus on Conqueror’s Haki blade coating in Chapter 1193 mirrors his iconic Mr. 1 fight in Alabasta — the last time Zoro underwent real-time philosophical breakthroughs during combat. That fight ended with him cutting steel. This one may end with him cutting something thought to be indestructible.

Our Analysis

What makes Chapter 1193 particularly compelling is how Oda is weaving together three separate “almost there” moments simultaneously: Luffy’s Gear 5 fading at the worst possible time, Zoro landing hits but failing to finish, and the box that holds answers but hasn’t been opened yet. This is classic Oda — creating a triple bottleneck that can only be resolved when all three threads converge. The question isn’t whether they’ll win; it’s in what order these locks get picked.

The most underappreciated element here is the role Usopp is likely to play. Japanese fan commentary consistently highlights that “God Usopp” always has a contribution that only he can make — and the timing of Biblo entrusting the box through Chopper (a crew member, not a giant) strongly suggests the tool inside is meant for a Straw Hat. The Elbaf mural’s Nika wielding a shield is particularly interesting: could the “tool” be a shield, and could Usopp — the crew’s designated sniper and long-range support — be the one to use it? That would be a stunning narrative payoff for a character who has always struggled with questions of courage and worthiness.

The Sommers fight also deserves more attention than it’s getting. The comment from Japanese readers that Sommers’s weapon seems to have special properties — compared to cursed blades like those in Kagura Bachi — hints that Oda may be expanding the lore of spiritually or Haki-imbued weapons. If the steel heart protecting Sommers can only be destroyed by Conqueror’s Haki, it functions as a direct parallel to whatever is protecting Imu — and Zoro’s breakthrough here could foreshadow a key role in the final confrontation with the World Government.

Theory Credibility Rating

The convergence of Biblo’s generational heirloom, Elbaf’s confirmed 800-year defeat at Imu’s hands, and the box’s battlefield-specific activation window provides extremely strong textual support — the only reason this isn’t a full five stars is that the exact contents of the box and Usopp’s precise role remain unconfirmed as of Chapter 1193.
