Kishi

This has 7 levels to it, each one more powerful than the last, but each one gets harder and harder to master. When used summons (depending on the level of mastery) one of the six knights to fight beside the user. While active the user is unable to move. Each knight is clad in medieval armor and each has its own unique weapon and ability. The seventh stage, when used, turns the user into a Knight of the Round, brandishing a large broad sword and a shield, the user is given superhuman strength but is unable to use any jutsu

*Naitoshakui- knighthood A-rank
the final form of the Kimura's kekkai genkai. it is seen as their sage mode, where as the 6 summons consciousness, intelligence, reasoning, and other cognitive abilities are imposed upon the user, increasing their mental abilities and allows for greatly increased processing of information from a battle, meaning that the user's reflexes are drastically improved while it slightly augments their other sense (ie touch, hearing, sight). The user's skin will turn a dull shade of gray, almost like an unpolished piece of metal, increasing the durability of the skin to almost a that of steel plate armor while. due to the user having multiple minds occupying a single brain, it is dangerous to stay in this state for more than 10 minutes or they risk losing all sense of who they were as a person, for even when in this state the user sounds as if there are multiple people speaking from the same body, and even going as far as referring to themselves as if they were a crowd.

kishi-knight
B-rank
a scaled down version of Kisho's naitoshakui, this jutsu allows simply one of the minds of the knight occupy Kisho's mind for an indefinite amount of time. while this jutsu gives no physical advantages, it allows Kisho to process incoming information twice as fast as normally or simply twice as much information at the normal rate, allowing for better reaction time and better strategic capabilities. since the knight's mind doesn't use Kisho's senses, any genjutsu that would affect one, wouldn't affect the other.
