Hiden: Powerful Lungs

Lightning Release: Crimson Shock
This jutsu cannot be used by anyone other than Shichi Shizuken.

Technique Description
Crimson Shock is a technique very similar to that of the Chidori and Raikiri in that it concentrates a substantial amount of lightning nature chakra in one’s palm. Similar to Lightning Release: Purple Electricity, it's a short to medium range jutsu that doesn't produce tunnel vision, so it doesn’t require the Sharingan.

However, although it's a fast lightning release jutsu, it's significantly slower than that of its counterparts. What it lacks in speed and penetrative piercing power, it makes up for in raw electrical power. A jab or thrust can be used to slightly increase its speed, but an open “tiger palm” or “slash” is often used to make contact with the target in close quarters encounters. Essentially, the speed of the jutsu is relative to how fast the user is rather than how fast the jutsu itself is.

Again, this jutsu is a jutsu centered around electrocuting the target, not piercing through the target's chest like Raikiri or Hell Stab.

In medium range situations, Crimson Shock can extend from the user like a tether or lightning whip to harmlessly incapacitate or lethally shock a target. Incapacitation followed by an incredible surge of electrical energy can torture, subdue, and even kill a target.

Crimson Shock is a lightning release jutsu invented by Shichi Shizuken. It has a dark and low chaotic sound and it appears red because of Shizuken's permanent spider-sage chakra. The jutsu can also be channeled through various mediums including Shizuken's sword, water, metals, etc. It increases the sharpness of her blade and her weapon's speed.
