Merman Gujutsu

Ningyo Gujutsu (人魚具術, Merman Weapons Style) is a fighting style used by the merfolk. It utilizes tridents and swords (and possibly other related weaponry) to deliver fast and powerful attacks. So far only the princes of Ryugu Kingdom have been shown using it.

Techniques

 * Koin Ryusui So (光陰流水槍): Used by Fukaboshi, he initiates this attack by spinning his trident rapidly. He then lashes forward and rapidly slashes his enemy with great strength. This attack is powerful enough to defeat some of the New Fishman Pirates' sea monsters.


 * Ryugu Romon (竜宮楼門): Used by Ryuboshi, he moves both of his swords forward rapidly, slashing his enemies numerous times. This attack was strong enough to defeat some of the New Fishman Pirates' sea monsters.


 * Shitchin Banpo (七珍万宝): Used by Manboshi, this is a powerful slashing attack, performed with both hands on the sword's hilt. It was strong enough to defeat some of the gigantic sea monsters sent against the three princes by the New Fishman Pirates.
