Damage: N/A
Description: This is one of the Hayabusa’s most advanced Neidan techniques. This is one of the non-traditional techniques created by Reborn after mastering both fuinjutsu and Neidan. This technique makes use of Dragon Chakra’s inability of being sealed and extends this affect to the user and their techniques. The process for this sealing technique requires the user to first train and store up a large amount of their Dragon Chakra into a single point of their body (similar to Tsunade’s Yin Sealing technique). The focal point for the seal will form a unique symbol that resembles a black and white koi fish circling each other like the Yin-Yang symbol. The second part of this technique is the actual activation of the technique. The user will activate one half of the seal or one “koi” and apply one of the following affects.
Black Koi: The black koi seal resembles a black koi fish with white eyes, whiskers, and a white circle on its head. This half of the koi seal applies to the user’s being. By activating this technique, the user coats their entire body in their Dragon Chakra and thusly become completely immune to sealing techniques. Seals that have been applied to the user will disappear from existence and all future attempts to seal the user in any way will inevitably fail. This includes barriers and other methods that fall into the category that would otherwise seal the user or prevent them from using techniques and abilities due to being or having been sealed or suppressed. The major drawback to this technique is that this technique also erases any self-imposed sealing techniques that are dormant or active. Hayabusa Dragon Chakra is indiscriminate between native and foreign chakra sealing techniques. The second drawback is that: by using this technique it prevents the use of the other half of this technique. This half of the technique creates a paradox with the other half of the technique in that; this technique erases all seals applied to the user including self-imposed ones. The second half of this seal would be included in this clause. However, because the second seal is also Neidan it cannot have a seal applied to it either thus a paradox occurs. To prevent this paradox, the user uses all the chakra in the seal for this half, which would cause the second half to fade out on its own without actually affecting the technique. When this seal is activated the user’s body from the neck down will be completely engulfed in black. Their sclera will become black as well.
White Koi: The white koi seal resembles a white koi fish with black eyes, whiskers, and a black circle on its head. This half of the Koi seal pertains to the user’s techniques. By activating this technique, the user’s chakra flow increases exponentially due to the chakra from the seal rushing throughout their entire chakra system. This results in every technique used after the activation possessing a significant amount of the user’s Dragon Chakra. The implementation of Dragon Chakra will prevent the user’s techniques from being sealed. This pertains to all non-Neidan techniques and will be maintained for a period of 400 chakra used by the user. This does not prevent sealing techniques from being applied to the user that would prevent certain types of techniques like the previous half of the technique. However once a technique is used with this half of the technique activated, it cannot be sealed or blocked by barriers or other methods of sealing. Because of the exponential flow increase every non-Neidan technique would have additional chakra added to it (+20) which would inevitably cause the jutsu to end quicker as every technique will use more chakra than necessary. This is an unavoidable consequence of the technique in exchange for its other benefits.
Note: The black koi seal will remain active until otherwise deactivated. Once deactivated the technique cannot be used again for the duration of the match.
Note: The white koi seal will remain active until the chakra cap is depleted or otherwise deactivated. However, if the technique is deactivated before the chakra is depleted the white koi can be re-activated (turn cost) with the chakra cap being where the user last had it when the justu was deactivated.
Note: Only one half of the seal can be used per match: the black koi requires all of the chakra stored in the seal and erases the white koi. Since all the chakra in the seal is required for the black koi, using the white koi even minimally will prevent the black half.
Note: when using the black koi users are unable to use non-Neidan techniques above S-rank.
Note: To learn this technique the user must have completed Fuinjutsu and be Jounin rank (by the clan's rank).
