As stated by Gatz, this fighting style allows the user to control vibrations around their limbs to generate shock. This shock is powerful enough to destroy a metal shield or defeat a strong man easily. Sai also claimed that these attacks are unblockable and reverberating, causing defenses to shatter.[1]
Variations
This fighting style can be utilized on any limb of the user's body, whether it be the head, fists, legs, or elbows.
Buto (武頭,Butō?, literally meaning "Military Head"): Chinjao jumps in reverse and headbutts the enemy. The strike is strong enough to stop Cavendish's Durandal and creates a shockwave while clashing.[3] It was first seen used against Cavendish in Corrida Colosseum. It is unknown if he uses vibrations in this attack. This is called Head-Arms in the Viz manga.
Kiryu Kirikugi.
Hasshoken Ogi: Kiryu Kirikugi (八衝拳奥義 錐龍錐釘,Hasshō-ken Ōgi: Kiryū Kirikugi?, literally meaning "Eight Impacts Fist Secret Technique: Drill Dragon Drill Nail"): A secret Hasshoken technique that Chinjao was able to perform thanks to his drill-shaped head. Chinjao hardens his head with Busoshoku Haki and headbutts the target. It was strong enough to split open layers of ice that not even fire or axes could breach, and was the "key" to Chinjao's treasure. After his head was flattened by Garp during their duel thirty years ago, he lost the ability to perform the attack.[4] After his head was reshaped by Luffy's Gomu Gomu no Thor Elephant Gun, he regained the ability to use this technique, and was shown using it in combination with Elizabello II's Light Version King Punch to shatter Pica's arm.[5] This is called Drill Dragon Nail in the Viz manga.
Hasshoken Ogi: Mukiryu Mukirikugi (八衝拳奥義 無錐龍無錐釘,Hasshō-ken Ōgi: Mukiryū Mukirikugi?, literally meaning "Eight Impacts Fist Secret Technique: Drill-less Dragon Drill-less Nail"): After Chinjao's head was flattened and he realized he could no longer open up the ice above his treasure, Chinjao renamed his technique. It was seen in this form during his fight with Luffy in the Corrida Colosseum, with the intent to kill the young pirate. Like the original technique, Chinjao hardens his head with Busoshoku Haki and headbutts the target, but the power is greatly diminished. Although it lacked the characteristic concentric circle vibration lines of other Hasshoken techniques, Chinjao still referred to it as a Hasshoken technique.[4] This is called Non-Drill Dragon Non Nail in the Viz manga.
Trivia
The ability to generate and control vibrations is similar to the Gura Gura no Mi.
This fighting style is only used by members of the Chinjao Family who are also members of the Happo Navy.
↑ 4.04.1One Piece Manga — Vol. 72Chapter 719, Chinjao uses his ultimate technique in a flashback, and performs the weakened version in the current timeline.
