Magma Release: Sulfuric Destruction

Sulfuric Destruction is a very powerful magma release jutsu. It is often considered to be a JMD (Jutsu of Mass Destruction) because of its powerful qualities.

Io Hametsu works through heat convection and various differences in pressure. The user begins this jutsu before radiating their fire chakra throughout the ground, heating it up as it goes. The heated melted rock would slowly begin to get denser and sink as other earth rises around it forming pockets of air and gas. As the heated rock sinks, the pressure around it will grow causing it to release the gases stored within along with huge amounts of sulfur oxide, a poisonous gas.

This would continue until the pressure grew to the point of where the ground was bulging up from the huge pocket of collecting sulfur oxide. The molten rock around it would form a denser and denser cap to the point of where the sulfur oxide simply explodes outward in a terrible volcanic eruption of sulfur, heat and molten rock.

Moisture in the air would begin to react with the sulfur creating a corrosive acid named Sulfuric Acid. This along with the sulfur oxide and sulfur dioxide would make a sickly yellowish cloud that would speed outwards sideways from from the explosion catching the opponent off guard.

Inhaling the toxic fumes has been proven fatal as the corrosive gases and acid have been known to suffocate and permanently damage lungs. This jutsu is particularly fatal to large groups of soldiers that are pinned down into positions with no way of escape except jumping up into a slaughter. That factor alone made this jutsu a forbidden jutsu in many countries after it was first witnessed by its creator. A man named, Emanyeru Kouseitan'i.
