Kagutsuchi (Sparky)

One of Dan Uchiha's most utilized Fire Release techniques and one of his signature moves to quickly end a battle. Building Fire Release chakra in his eyes and focusing on a target or targets he can manipulate the surrounding heat of his environment causes different effects such as removing, blocking, or increasing the amount heat.

The user can cause a living target to suffer from extreme dizziness or even cause them to faint by inducing an heat syncope of the target by causing the surrounding heat to increase around that target restricting blood flow to the brain as well as heat spasms. If the user further increases the heat exposure of the target then they can possibly induce a severe heat stroke or cause dehydration causing the target to potentialy die. If the user however removes an abundance of heat or rather blocks heat from getting to the target, they may succumb to slowed moved and possibly hypothermia to different parts of their body.

In addition the user is able to use the aid of other heat sources or fire caused by other techniques to increase the effectiveness of the technique. As long as the target is within the eyesight of the user this technique can be used. User's that possess the Byakugan can use this technique over profound distance. This technique also allows the user to cancel out other Fire Release techniques or enhance them by manipulating the heat signature.

When this technique is in use the user's eyes glow red and they are also able to see living creatures heat signatures as well as intense sources heat. This technique however, cannot extinguish the Amaterasu, but can guide it elsewhere.
