Jiko Kieru

The disappearing or vanishing self technique operates by sealing the degrees of detection surrounding a shinobi and releasing incoming (in some cases outgoing) signals capable of giving away a shinobi's position. This sealing capacity extends across and beyond the visible and audible spectrums.

Background
Throughout his life, Batista Kittu remained obsessed with stealth. He found the Ongyōjutsu (隠形術 disappearing and concealing techniques) that a shinobi learns in his formative years and practices for the rest of his days to be inadequate. He searched for a method sealing the avenues of detection that a shinobi encounters in the field. Thus Kittu invented the Jiko Kieru, the Disappearing Self.

Preparation
From sensei to seito, a subject is inscribed on the inside of the breastbone with a transcription seal formed from a chakra reactive dye made from bakemono and ōnyūdō excretions. This is done when the subject first begins to study ninjutsu.

Execution
The user channels his chakra into his sternum with the appropriate hand signs. These encoded hand signs different are for every user. The seal activates and creates a barrier with varying characteristics, depending on the level of skill of the user.

First Level
User learns to create a barrier capable of sealing incoming visible light and releasing it from the opposite side of the barrier.

Second Level
User develops a barrier capable of sealing and releasing all incoming light frequencies capable of detecting a human being.

Third Level
User develops a barrier capable of sealing all incoming and outgoing acoustic and thermal frequencies. The user's own vibrations and heat radiation are sealed. This, however, results in quicker chakra consumption.

Sealed Presence
The ultimate expression of the Jiko Kieru, the sealed presence, was obtained by its inventor, Kittu Batista. One develops a sealed presence when all incoming light, vibration, chakra, or pressure becomes sealed on one side of the barrier only to be unsealed on the other. A shinobi with a sealed presence cannot be detected by any known means.
