Explosion Release: Execute System

If any unknown material or bacteria were to enter his body, Hayato would use this technique to literally transfer Explosive Chakra via chakra flow to his white/red blood cells to combat, or counter whatever has intruded his body. This isn't harmful to Hayato's body, because as an Explosion Release user, his body is more than accustomed to explosions. Also, when his blood cells come into contact with the intruding substance/virus, it doesn't actually burst. In fact, it burns away at the intruding substance.
