Shinkeishin

Shinkeishin (神経栓, lit. Neurone Stopper) is the Kekkei Genkai of the near-extinct Makise Clan which gave them the ability to manipulate the nervous system. This ability is greatly feared in the Ninja World that eventually led to the genocide of Makise Clan.

Ability
Shinkeishin provides the user to the access of myriad special abilities that concerned with nervous system. The abilities are divided into two parts, first is "sensing" and second is "controlling". The first power of Shinkeishin is capable to sense the nervous system of one person including the user himself or herself by using their brain. Eye contact is unnecessary and even by closing the user's eyes, the ability is still working. Experienced user could even identify the contents of the nerve impulse.

The second power of Shinkeishin, and the most prominent ability is granting the user to manipulate the nervous system of one person. Mostly the user will manipulate their own nervous system because this ability will only work if the target doesn't resist. This ability grants the users to slow down, blocking or even destroy nerve impulses that are traveling to the brain. Normally, the users will do this on their somatosensory system's nerve impulses in order to disable pains.

The third power of Shinkeishin is unknown. The ability is yet to be awaken, and it is said that the ability is capable to control the Ninja World, and this is the main reason that led to the destruction of Makise Clan.
