Imu’s Vohu is the Blade of Nothingness revealed in One Piece Chapter 1188. The sword causes nearby vegetation to dry out and lets Imu pierce Luffy while he is using Gear 5. However, the manga has not confirmed that Vohu drains life force, absorbs Haki, negates Nika’s power, or belongs to a recognized sword grade.
“Imu Void Sword” is a common search term, but Vohu is the name used by the official English release. The distinction matters because early fan translations also used Bohu, Bofu, Void, and Sword of the Wailing Void. Those variations describe the same Chapter 1188 weapon, not separate swords.
Major manga spoilers: This guide covers canon information through One Piece Chapter 1188, released in English on July 12, 2026. It excludes unverified leaks for later chapters.

What Is Imu’s Vohu Sword in One Piece?
Vohu is a named sword that Imu manifests during the battle with Luffy on Elbaph. Its official English description, Blade of Nothingness, matches the visible effect produced when the surrounding forest loses moisture and vitality.
The weapon appears after Luffy’s new Gum-Gum Genie technique fails to give him control of the fight. Imu changes tactics, brings out Vohu, clears the surrounding vegetation, closes the distance, and drives the blade through Luffy.
That sequence establishes Vohu as more than an ordinary cutting weapon. Its arrival changes the environment before it touches Luffy. The chapter does not yet explain whether that effect comes from the sword itself, Imu’s supernatural power, Omen, Haki, or a combination of those systems.
For Imu’s wider identity, political authority, transformations, and known abilities, read AnimeCrisp’s full guide to who Imu is in One Piece. Vohu is one part of that larger power set.
Is It Called Vohu, Bohu, Bofu, or the Void Sword?
Vohu is the official English name, while Bohu, Bofu, and Void Sword are translation or romanization variants.
Chapter 1188 is titled “Vohu” on VIZ and MANGA Plus. Before the official release, fan summaries translated the term in several ways. That created multiple competing keywords for the same object.
| Name | Where it comes from | How to use it |
|---|---|---|
| Vohu | Official VIZ and MANGA Plus English rendering | Use as the primary name |
| Blade of Nothingness | Official descriptive translation associated with Vohu | Use as the English explanation |
| Bohu | Alternative romanization linked to the likely Hebrew source | Useful for translation context |
| Bofu | Phonetic fan romanization of the Japanese rendering | Recognize as a variant, not a separate weapon |
| Void Sword | Early fan translation and common search phrase | Useful as a secondary keyword |
| Sword of the Wailing Void | Expanded unofficial translation | Do not present as the official VIZ name |
Using Vohu first helps the article match the official release. Including “Imu Void Sword” naturally also helps readers who encountered the weapon through spoilers, videos, or early translations.
What Does Vohu Mean?
Vohu most likely refers to the Hebrew word bohu, which is associated with emptiness, void, waste, and desolation. The official romanization uses a V, but Hebrew transliteration can produce forms such as bohu or vohu.
The word is best known from the phrase tohu wa-bohu. Academic discussion commonly translates the phrase as “unformed and void,” while lexical references define bohu through ideas such as emptiness and waste.
The connection fits the weapon’s presentation. Vohu leaves the forest dry and empty, while Imu represents a system built around control, erasure, and the suppression of forbidden history.
That does not prove every religious or creation-story interpretation is intended by Eiichiro Oda. No author note has officially explained the name. The linguistic link is strong, but larger claims about Imu representing a specific biblical figure remain theories.
When Does Imu Use Vohu?

Imu first uses Vohu in Chapter 1188 during the fight with Luffy on Elbaph.
Luffy enters the confrontation in Gear 5 and reshapes himself with Gum-Gum Genie. He attempts to pressure Imu with his awakened freedom and later launches a surprise attack. Imu stops the attempt and continues controlling the exchange.
Imu then produces Vohu. The surrounding trees dry out, reducing the cover around the battlefield. Imu reaches Luffy and impales him before judging him against the original Joy Boy.
The scene matters because it follows Luffy’s most imaginative new application of Gear 5. Vohu shifts the battle from visual comedy to a direct reminder that Luffy’s awakened form can still be wounded.
What Powers Does Vohu Have?
Vohu has two clearly demonstrated effects: it dries the surrounding vegetation and functions as a blade capable of piercing Gear 5 Luffy. Everything beyond those results needs a more careful label.
| Claimed power | What Chapter 1188 shows | Current status |
|---|---|---|
| Environmental desiccation | Trees and plants dry out when Vohu appears | Confirmed |
| Piercing damage | Imu drives Vohu through Gear 5 Luffy | Confirmed |
| Weapon manifestation | Imu produces the named blade during battle | Confirmed visually; exact mechanism unknown |
| Life-force absorption | The forest withers, but no explicit life-force explanation is given | Not officially confirmed |
| Haki absorption | No statement shows Vohu taking Haki from Luffy | Not officially confirmed |
| Anti-Nika effect | Vohu wounds Luffy, but the chapter does not call it a Nika counter | Fan theory |
| Regeneration negation | No lasting-healing test is shown in Chapter 1188 | Unknown |
| Instant death | Luffy is severely wounded, but his death is not confirmed | Not confirmed |
Does Vohu Drain Life Force?
Vohu may remove moisture or vitality from its surroundings, but direct life-force absorption is not officially confirmed.
The forest’s sudden decay supports the idea that the sword carries a desiccating or withering effect. However, the manga does not show energy flowing from the trees into Imu. It also does not state that the blade steals lifespan, soul energy, or physical strength.
“Life-draining sword” is therefore a reasonable theory, not a confirmed ability name. The most accurate description is that Vohu causes visible environmental withering.
Does Vohu Drain or Absorb Haki?
No Haki-draining ability has been confirmed for Vohu.
Readers have compared the sword with Enma because Enma draws out its wielder’s Haki. Vohu’s scene does not establish the same mechanic. Luffy is pierced, but the chapter does not show his Haki being pulled into the weapon or removed from his body.
The blade may still involve Haki. Top-level combatants frequently combine weapons with Armament or Conqueror’s Haki. Yet the exact coating used in this attack is not explained. AnimeCrisp’s guide to Conqueror’s Haki in One Piece covers the established rules, which should not be extended to Vohu without manga evidence.
Why Could Vohu Hurt Gear 5 Luffy?
Vohu could hurt Luffy because Gear 5 does not make him immune to blades, piercing attacks, Haki, or overwhelming force.
Luffy’s body has rubber properties, but sharp weapons have always remained dangerous. Gear 5 gives him extreme freedom over his shape and surroundings. It does not convert every attack into harmless cartoon damage.
Four factors could contribute to the Chapter 1188 result:
- Vohu is a piercing weapon: Rubber resistance to blunt force does not create complete protection against sharp blades.
- Imu controls the timing: Luffy fails to establish momentum before Imu closes the distance.
- Vohu has an unexplained supernatural effect: The withering forest shows that the sword does more than ordinary steel.
- Haki may be involved: This is plausible at Imu’s level, but Chapter 1188 does not explain the exact coating behind the strike.
The scene does not prove that Vohu permanently disables Gear 5 or specifically negates the Hito Hito no Mi, Model: Nika. One successful strike is not enough to define an anti-Devil Fruit rule.
Is Vohu an Anti-Nika Weapon?
Vohu is not officially identified as a weapon created to counter Nika or Joy Boy.
The theory exists because Imu knew Joy Boy and uses Vohu against the current user of the Nika fruit. The name’s association with emptiness also contrasts strongly with the freedom, laughter, and liberation represented by Sun God Nika.
That contrast creates meaningful symbolism, but symbolism is not the same as a confirmed combat mechanic. The manga has not said that Vohu was forged for Joy Boy, that it negates Nika, or that it wounded the original Joy Boy during the Void Century.
Is Vohu Part of Imu’s Devil Fruit or Omen Power?
The source of Vohu is not officially classified. It appears within Imu’s supernatural arsenal, but Chapter 1188 does not provide a Devil Fruit name, weapon origin, or narrator explanation for the blade.
Imu can use dark energy, transformations, possession, contracts, and summoned weapons. Vohu may be created through the same underlying ability as Omen, or it may be a separate weapon that Imu can call into battle.
Until the manga defines the system, three classifications remain possible:
- A weapon created from Imu’s supernatural energy
- A physical sword summoned or stored through an unknown ability
- A weapon tied to Imu’s still-unclassified Devil Fruit or contract system
None of these options should be presented as settled fact.
Is Vohu a Black Blade or Supreme Grade Sword?
Vohu is not confirmed as a Black Blade, Supreme Grade sword, or any other Meito grade.
A dark appearance alone does not make a weapon a permanent Black Blade. Confirmed Black Blades such as Yoru and Shusui have explicit status within the story. Vohu has not received that classification.
| Weapon | Confirmed classification | Known special trait |
|---|---|---|
| Vohu | No grade or Black Blade status confirmed | Dries nearby vegetation and pierces Luffy |
| Yoru | Supreme Grade and permanent Black Blade | Dracule Mihawk’s signature weapon |
| Enma | Great Grade blade | Draws out excessive Haki from its wielder |
| Shusui | Great Grade and permanent Black Blade | National treasure of Wano |
Vohu may eventually receive a formal grade, but its current danger comes from its demonstrated effect and Imu’s use of it, not an announced sword ranking.
Does Using Vohu Make Imu a Swordsman?
Using Vohu does not automatically place Imu in the story’s traditional swordsman category.
Imu fights through several different methods, including supernatural attacks and transformed weapons. One named blade is not enough to prove that swordsmanship defines Imu’s primary fighting style.
This also means Vohu does not currently change Dracule Mihawk’s title as the World’s Strongest Swordsman. A future chapter would need to explain Imu’s relationship with swords and whether Vohu follows the same combat tradition as Meito blades.
The Crocodile Parallel in Imu Stabbing Luffy
Imu piercing Luffy with Vohu visually echoes Crocodile’s first major victory over Luffy in Alabasta.
In Chapter 178 and anime Episode 110, Crocodile impales Luffy with his hook after showing the gap between an inexperienced pirate and a Warlord. Luffy survives, studies the matchup, and later returns with a method for touching Crocodile’s sand body.
Chapter 1188 repeats several elements:
- Luffy confronts an opponent connected to the World Government’s power structure.
- The opponent controls the fight and pierces Luffy through the torso.
- Luffy is dismissed as too weak or inexperienced for the role he claims.
- The defeat exposes a problem that raw confidence cannot solve.
The parallel does not guarantee that the Elbaph battle will repeat Alabasta’s three-round structure. It does suggest that Luffy’s first serious exchange with Imu is designed as a setback, not proof that Gear 5 has reached its final ceiling.
What Does Vohu Reveal About Imu and Joy Boy?
Vohu reveals that Imu can measure Luffy against a personal memory of Joy Boy and currently finds Luffy weaker.
Imu does not treat Gear 5’s appearance as proof that the original Joy Boy has literally returned. Instead, the ruler recognizes the visual and ideological connection while distinguishing Luffy from the person remembered from the Void Century.
That distinction is important. Luffy can inherit Joy Boy’s will and use the same Nika fruit without already matching Joy Boy’s experience, Haki, or mastery.
Vohu becomes the weapon that demonstrates this gap. Its emptiness theme also forms a clear narrative contrast with laughter, liberation, and the Drums of Liberation. That thematic reading is strongly supported by the scene, although the manga has not formally named Vohu as Joy Boy’s opposite.
Did Imu Kill Luffy With Vohu?
No. Chapter 1188 does not confirm that Luffy dies after Imu stabs him with Vohu.
The injury is severe, and the chapter ends before its full consequences are explained. A cliffhanger is not the same as a confirmed death.
Luffy has survived impalement, poisoning, crushing attacks, and temporary battlefield defeats before. That history does not make him immune to Vohu, but it prevents an evidence-based article from declaring him dead without an explicit manga confirmation.
Later official chapters may reveal whether Vohu leaves a special wound, interferes with Gear 5 recovery, or requires outside treatment. Those possibilities remain unresolved at the end of Chapter 1188.
Does Vohu Prove Imu Is Stronger Than Luffy?
Chapter 1188 shows Imu decisively outperforming and wounding Luffy in their first major exchange. That is strong evidence that current Luffy has not yet mastered everything needed to defeat Imu.
It does not establish every possible condition of a final battle. Luffy does not understand Vohu, Imu’s complete abilities, the contract system, or the opponent’s history with Joy Boy. One encounter can show a present gap without fixing the final outcome.
AnimeCrisp’s list of the strongest One Piece characters considers confirmed feats, Haki, story role, and unresolved limitations. The separate guide on whether Imu is the final villain explains why winning on Elbaph and being the series’ last opponent are different questions.

Is Imu’s Vohu Sword in the Anime?
No. Vohu has not appeared in the One Piece anime.
The weapon currently belongs to manga-only Elbaph material. No official anime episode number or adaptation date has been announced for Chapter 1188.
Gear 5 debuted much earlier in anime Episode 1071. Watching that episode explains Luffy’s awakened form, but it does not include Gum-Gum Genie, Imu’s Elbaph battle, or Vohu.
Why Vohu Matters to the One Piece Final Saga
Vohu matters because it gives Imu a direct answer to Luffy’s current strongest transformation.
Before Chapter 1188, Imu’s threat came from secret political control, country-level destruction, contracts, possession, and supernatural authority over the World Government. Vohu adds a precise close-range weapon that can wound Luffy personally.
The sword also joins three major Final Saga themes:
- Erasure: Imu removes people, nations, and history from the world.
- Emptiness: Vohu leaves life and structure stripped away from its surroundings.
- Opposition to liberation: The Blade of Nothingness confronts the awakened power associated with Nika and Joy Boy.
Its greatest unresolved question is not whether it looks powerful. Chapter 1188 proves that. The real question is what rule controls the blade and what Luffy must learn before he can survive it in a decisive battle.
Final Verdict: What Is Imu’s Vohu Sword?
Vohu is Imu’s Blade of Nothingness, first revealed in One Piece Chapter 1188. It dries the surrounding vegetation and pierces Luffy during Gear 5, establishing it as one of Imu’s most dangerous close-range weapons.
The official evidence stops there. Vohu is not yet confirmed as a life-draining sword, Haki absorber, anti-Nika weapon, Black Blade, Supreme Grade blade, or Ancient Weapon.
Its name likely echoes the Hebrew bohu, associated with emptiness and desolation. That meaning fits both the withered forest and Imu’s role as the force opposing Nika’s liberation. The symbolism is clear, while the sword’s complete combat rules remain unresolved.
