Aizunogi

The Aizunogi is a special Dojutsu awakened by Kiritsu Taisei during his days as a Chuunin. The dojutsu originally does not possess a name, but Kiritsu decided to name it after the moniker the people of Getsugakure gave him. This dojutsu is not hereditary, but rather is a dormant gene from the earliest members of the Taisei clan that is rarely awoken. Those who do awaken it are granted a sort of sixth sense, granting them sensing abilities similar to the Byakugan, but on a more thorough scale. Not only does the dojutsu detect chakra signatures, but can also detect other forms of energy signatures. In the case of chakra, the color of the chakra glows a specific color depending on the target's nature affinity. Those with Water Release will have a blue chakra aura, Fire Release has a red aura, etc. It can also track chakra signatures, showing a trail where someone moved from. Again, this trail is color specific to the target's affinity. There are two other abilities granted by Kiritsu's awakening of the dojutsu. The second grants him enhanced vision, allowing him to see even in very poor visibility. This benefits his stealth greatly as it allows him to hide in dark areas without having to sacrifice his already subpar vision. The third ability works in tandem with his external chakra signature. Because his chakra forms a large, round aura around him instead of circulating inside of his body, he can use his dojutsu to bring the chakra to life, allowing it to work as a shield, protecting the user similar to the frame of a low end Susanoo. The only limit to this is how much chakra Kiritsu had when he activated the ability.
