Noryokugan

This is the of the Helixian Clan and has only appeared four times in the history of the clan, all in the Korimachi Branch, appearing in the Helixian Clan Leader, Kekkei Korimachi, Siasha Korimachi, and Ace Korimachi. When in use, black, tri radial symmetric patterns overtake the iris, and in some phases, the patterns rotate and or move during its duration. This dojutsu is distantly related to the Sharingan and the Rinnegan. The Helixian Clan leader wanted to collect the knowledge of the ninja world, as soon went on to use the eyes to achieve that goal. This eye carries with it various techniques, including the Guardian of Inner Will (wiru no innā gādian) distant relative Susanoo, allows the user of these eyes to use unique and powerful jutsu, however these differ greatly from the powers of the Sharingan as these revolve around a Space-Time Techniques.

Uses
The Guardian of Inner Will is currently in use by Ace Korimachi and to use it, he has to be pushed to his absolute limit while his Ultimate Omegatri is active. The main thing about the Guardian of Inner Will is that it is similar to that of the Mangekyo Sharingans Susanoo, except it's much smaller, has somewhat less power, but it provides the user with a lot more mobility and it surrounds the user like a suit of armor. Conversely however is the fact that for each phase or Omegatri, there's also a Inner Guardian Phase. The Guardian of Inner Will serves as a protector of the user when there's no other option. The user can use their technique through the Guardian, allowing the ability to be amplified in the process. The Guardian will continue to serve and protect the user for 5 minutes, and when that time is up, the users chakra will serve as it's source of fuel while it provides the power and for every 5 minutes afterwards, the amount of chakra consumed by the Guardian will double (e.g. 2nd 5 minutes = 1/10 chakra comsumed, 3rd 5 minutes - 3/10 chakra consumed, 4th 5 minutes = 6/10 chakra consumed, which by now mean the guardian will vanish, unless chakra is restored)

Obtaining the Guardian of Inner Will
One must have reached the Ultimate or Final Phase of the Tri-Force

Weaknesses
The main weakness is that it has low defense, a trade-off for ability amplification, and increased mobility, as well as the host of the technique only has 5 minutes to recover or retreat, using the little chakra they have left.
