Kourinkoshiki Sesshou

The Callous Descent of the Dying Tree is a certain-kill technique created by Tsukyū utilizing her Forest Release. It is a gruesome technique that produces gruesomely venomous acid capable of disintegrating flesh. It is extremely versatile, seemingly impossible to overcome by normal means.

Overview
By creating a tree infused with, Tsukyu is able to summon a tree that seems almost dead, on the verge of withering. This tree automatically brings fear to any who feel the sheer exuded from it. As one gets closer to this tree of death, they would slowly begin to feel that the oxygen is fleeting from their body, quickly brought to their knees. Not long after this, the tree starts to secrete a purple gas, clearly filled with acid. It is not long until an entire battlefield is covered with this acid, capable of reaching the size of an entire village. Anyone who breathes or smells this acid slowly feels as though they are sick, they begin rapidly coughing and vomiting blood. Their skin feels as though a thousand roaches have invaded it, slowly getting eaten from the inside-out. The unfortunate souls that fall victim to this would remember the agony, pain, and suffering they experienced as their entire body was getting eaten by the ominous gas. Even the strongest of shinobi fall victim to this technique all the same, only avoidable if one has a or other means to prevent the acid into their systems. Days after this occurs, it is still a hazard to walk the barren land as a single whiff of it is enough to paralyze someone for their entire lives. Tsukyū is also able to make it condensed into a singular area instead of spreading a wide distance, effectively making it much more dangerous in said area. A single usage of this technique brings forth innumerable suffering and agony to all those who with take it.
