Exploding Human Technique

When a Ketsuryūgan-wielder makes direct skin contact with a target's, they can infuse some of their chakra into the target. The said chakra becomes poisonous to the target, making their bodies unstable. Should the target then begin to bleed, the chakra will be set off, causing the victim's body to become consumed in a pitch-black substance before inflating in a grotesque manner and finally exploding in very destructive manner. Only by rendering the target unconscious (via genjutsu) will nullify the explosion. With proper medical aid, the poisonous chakra can be extracted, saving the victim completely.
