Finger Nerve Spark

The Finger Nerve Spark is a hidden technique that is exclusive to the Ishiyama Clan. This technique involves sending impulses of lightning into the target's nervous system through the user's fingers, causing a number of adverse effects. This technique can cause the target to feel a certain sensation, usually mild to severe pain, but the chosen sensation can span from being scratched by a cat to being set on fire. It can also disorient the terget's nervous system, or even shut it off altogether, essentially killing the target. Kazuhiko Ishiyama has advanced the technique further, allowing him to unleashes bolts of lightning from his hands.
