Bloodletting

Bloodletting is a formidable kinjutsu developed by Senku, to use at first Senku would injure any part of his body causing blood to freely flow out of his body. Since, he has experimented with his body so many times his blood consists of parasites capable of feeding on chakra. Once, out of his body these parasites would spread throughout the region mixing with the air, when inhaled these parasites would begin to absorb chakra from it's host, slowly depleting the target of it's chakra. If one possesses a Kekkei Genkai, these parasites would attack that particular cells and would disintigrate that particular blood line. This leaves the target in a mummified conditions, since they are stripped of their chakra completely and further their kekkei genkei is disintigrated, death follows shortly.
