Jingoro Amayo

雨夜陣五郎

Ugly inside and out, Jingoro plots to leave every last Jouga in his slimy wake. When his body comes into contact with salt, Jingoro trasnforms into a monstrous jelly-like state in which he's able to sneak behind enemy lines undetected, or even into his opponet's body by entering through any exposed orificies.
