Acidic Sludge

An alternate poison to Nexus Poison that Kyoya Shirogane created while in Sunagakure. As opposed to the Nexus Poison's psychological and internal effects, the Acidic Sludge is a corrosive, highly acidic substance created through the combination of various chemicals, the likes of which are installed into each of Kyoya's puppets, including himself, only meant to be expelled through specialized pipes, for to apply the substance onto weapons would ensure the weapon's destruction. The Acidic Sludge substance is highly corrosive, able to melt/corrode even the toughest of substances, burning straight through human skin, and most armors. Even the slightest bit of contact with the liquid can cause disastrous damage to an object. When emitted in large quantities in liquid form, the acid has a tendency to release noxious fumes, which are capable of considerable internal damage if inhaled in large quantities, yet the most common symptoms of fume inhalation is a painful burning sensation in the nose and throat. The Acidic Sludge acid is commonly infused with Kyoya's own chakra in order to enhance it's range and corrosive capabilities, whilst protecting Kyoya's body and that of his puppets from the acid.
