Overview

The Happo Navy is one of the West Blue's Three Major Powers, alongside the Marines and the Five Great Mafia Families. Its long-running hostility with the Marines stems from Garp's past battle with Chinjao, which left the organization in decline after Chinjao lost access to its buried treasury. 6

Although regarded as the strongest pirate crew in the West Blue, the Happo Navy operates with the legitimacy and backing of the Flower Country. It collects ransom from civilian vessels but is known for avoiding indiscriminate slaughter, favoring sustainable piracy over destroying its sources of income. 25

History

The Happo Navy underwent a generational transition following Chinjao's leadership, with uncertainty over who would become its next Pillar worsening its conflict with the Marines. 6 Sai later emerged as the crew's current leader and Pillar, while his brother Abu served as Vice Pillar. 25 39

The crew acquired portions of the Capone Family's divided weapons shipment at sea. During this operation, Sai and Abu captured Hina and Jogo aboard a luxury cruise ship; Jogo was kept aboard to appraise the Navy's stolen antiques. 25 26

After Jogo escaped and later survived a battle with Daz Bones, Sai brought him back onto the ship. The Happo Navy enslaved Jogo, but he used his newly awakened Observation Haki to study its fighters and secretly reproduce Hasshoken. 28 29 32 34

The Marines' attempt to ambush the Happo Navy at Crab Claw Orchid Island failed when Chinjao intervened. Soon afterward, Jogo defeated Sai with Conqueror's Haki, subdued Abu, and delivered Sai, Abu, and surviving pirates into Marine custody through Hina. 37 39 40

Sai's capture destabilized the organization and prompted peace negotiations with the Marines. Chinjao chose to proceed with the talks despite the crew's suspicion that the Capone Family was setting a trap. 47 The negotiations ultimately established peace in the West Blue, though the Happo Navy remained hostile toward Jogo. 50

Hasshoken Rules

Serious disputes aboard the ship are settled under the Hasshoken Rules: the involved parties fight in a ring, the winner is deemed right, and the loser accepts punishment. 31

Sai enforced these rules even against Abu, ordering him whipped twenty times after Abu replaced a subordinate in a challenge against Jogo and lost. 32

Recruitment and Social Hierarchy

• The crew calls even ordinary members “Hasshoken disciples,” though most pirates are taught only a weakened boxing derivative rather than the Chinjao family's true martial art. 31 33
• True Hasshoken is a secret art passed down only through Chinjao's direct bloodline. 33
• The crew openly uses slavery and public humiliation to enforce hierarchy; Jogo was assigned deck-cleaning and prison duties after being declared a slave. 29 32
• Valuable specialists may be treated well outwardly while being regarded as property. Sai planned to recapture and enslave Jogo after promising to release him. 26 27

Abilities & Military Assets

Hasshoken

The Happo Navy's defining martial art generates vibration-based shockwaves that can strike without direct contact, penetrate defenses, and function as a defensive barrier. 25 32

• Sai could combine Hasshoken with Armament Haki, greatly increasing the power and penetration of his attacks. 25 38
• Sai's shockwaves could numb Jogo's body, damage the ship's deck at range, and obstruct counterattacks by surrounding Sai like armor. 32
• Abu used Hasshoken with an axe, giving the weapon both conventional lethality and vibration-based penetrating force. 38
• Ordinary crew boxing lacks the true vibration power of the Chinjao family's technique. 33

Armament Haki

Sai possessed Armament Haki by the time the Happo Navy seized the cruise ship. His Armament-enhanced kicks shattered the deck and overwhelmed Jogo's normal Hasshoken defense. 25 38

Fleet and Maritime Operations

• The main fleet used a large tiger-headed pirate ship capable of overpowering and boarding a luxury cruise ship. 25 27
• The Navy seized civilian ships, destroyed lifeboats to prevent escape, and collected ransom from passengers. 25
• Its forces were divided among multiple ships to collect portions of the Capone Family's weapons shipment across different islands. 36
• The Navy maintained enough military strength to stand against the West Blue Marines and force them into negotiations. 6 47

Major Arcs

West Blue Power Struggle

The Happo Navy's generational change and entrenched feud with the Marines established it as a destabilizing force in the West Blue's balance of power. 6

Weapons Shipment Operation

The Navy became the buyer and collector of the Capone Family's smuggled weapons shipment. Its main fleet captured Hina and Jogo after boarding the cruise ship used for the sea-based transfer. 24 25

Jogo's Captivity

Sai employed Jogo as an antique appraiser, then attempted to keep him as a permanent slave. Jogo escaped at Iris Island after sending Hina's evidence against the Capone Family to Marine Headquarters. 26 27

Conflict with Jogo

Jogo returned to the Happo Navy ship after his battle with Daz Bones and was made a slave. He awakened Observation Haki, learned Hasshoken through observation and imitation, defeated Abu, and survived Sai's ten-move challenge to study the martial art. 28 29 32 34

When the Marines' ambush failed, Sai moved to execute Jogo. Jogo defeated Sai almost instantly with Conqueror's Haki, after which Abu massacred fellow crew members to bargain for Sai's life. 37 39

Sai's Capture and Peace Talks

Hina took custody of Sai, Abu, and the surviving pirates, with the Marines publicly claiming the victory. 40 44 The resulting crisis led Chinjao to accept peace talks with the Marines, which ended in a West Blue truce despite the death of Capone Bege during the negotiations. 47 50

Relationships

• Flower Country — The Happo Navy is backed by the World Government-affiliated kingdom. 25
• Marines — Longstanding enemies due to Garp's conflict with Chinjao; later entered peace negotiations after Sai's capture. 6 47 50
• Capone Family — Acquired the family's divided weapons shipment; later joined its proposed peace talks, while Capone Bege attempted to use the Navy against Jogo. 36 47 48
• Jogo — Captive, forced appraiser, slave, and eventual enemy who defeated Sai and caused the Navy's major setback. 26 29 39
• Hina — Captured Marine whose investigation exposed the weapons operation; she eventually took custody of Sai and the surviving pirates. 25 40

Trivia

• The Happo Navy's prior leader, Chinjao, had a reported bounty of 500 million Beli. 25
• The crew's reputation for not routinely killing hostages influenced Hina's decision to surrender rather than force a hopeless fight. 25
• Despite being a pirate force, the Happo Navy's political weight was significant enough that the Marines prioritized a formal peace agreement after Sai's capture. 47 50
