Nuru

Neru is an angler fishman that fought Zoro during the Fishman Island Arc.

Weapons
Hyouzou was a swordsman, and his weapons of choice were seven sabers and a katana which he was always seen carrying around. Hyouzou can be recognized as a very proficient swordsman. He is later confirmed to be the strongest swordsman on Fishman Island; even while (or rather because of being) intoxicated, Hyouzou shows tremendous swordsmanship, swinging three swords to easily take down members of the New Fishman Pirates. His last resort appears to be coating his eight swords with his deadly venom. However, after his defeat and his body became weak, it is unlikely he is capable of any swordsmanship close to the level he could do when he was younger.

Energy Steroids
Like the rest of the crew, Hyouzou had taken the Energy Steroids during the battle against the three princes of Ryugu Kingdom, who are crowned the strongest soldiers in the entire island, and was able to overpower them due to this. The drug doubles his strength per pill, but shaves off a portion of his lifespan. After he overdosed on Energy Steroids, he underwent a transformation similar to Hody, in which his hair turned white, and was afterwards able to cut iron with ease. The pills, however, had another side effect of making him old and weak after he was arrested, which causes him to lose all the strength he naturally had.
