The Ajna Seal is a seal which is reputed to be the pinnacle of chakra control, chakra absorption and chakra transfer. Over a period of time the user of this circular seal absorbs chakra from themselves and a proportionate amount of nature energy from the world around them to archive it into a specific point on their body—the forehead.
When enough chakra and nature energy is siphoned, the seal surfaces on the wearer's forehead. Once released, the seal breaks up and turns black, spreading across the user's body before disappearing, the forehead seal returning. It can automatically cause one to enter Sage Mode.
After release, disappearance and subsequent reappearance, the seal becomes a crescent shape until it is dormant.The stored chakra and nature energy is then released into their body, greatly amplifying the power of their techniques and one's overall ability. The seal will permanently remain in the center of the user's forehead, presumably so that the user can keep on benefiting from its effects. This seal is symbiotically linked to Chūkode's leech summonings. It is meant to be combined with the Thousand Year Restoration Technique for incredible healing. What the Ajna Seal also functions as is a "hard-drive backup" of sorts where one's memories and genetic make-up are stored in order to preserve the body during healing. This warehouse of storage can section of portions of itself if need be so that harmful substances that enter the body will be automatically quarantined so as not to cause the wearer any biological harm.
The seal is also rather frugal with its energies—it is in all its complexity designed to ration chakra and nature energy so that regardless of how much chakra one has, even if they are down to 25% out of 100, when they seek to use the seal and its corresponding jutsu, 50% of their 25% chakra is automatically divided out and set aside for restoration. In such a case, healing speed is decreased. The power of the seal can be transferred to another person and may instantaneously be used.
