Tsubasa Clan (Kagerō)

The Tsubasa Clan (翼族 Tsubasa Ichizoku)  is a clan vaguely known for its dōjutsu kekkei genkai, the Senrigan and their  Ice Release kekkei genkai.

History
Originating from The Land of Mountains The Tsubasa clan lived peacefully in Kagerō Village. 20 years before the destruction of Kagerō Village, the Tsubasa clan lived there peacefully and lead a relatively normal life. The Tsubasa clan were relatively pacifistic in nature so they didnt get into many fights, however, when they did they were feared on the battlefield because of their Ice Release kekkei genkai.

Sometime during their time in The Land of Mountains they bonded and contracted with the Tengu that resided there, who became the Tsubasa clans exclusive summoning. However before the Tengu would contract with them, they at first had to prove themselves worthy by defeating one of them in battle, the head of the clan at that time, Buzen, volunteered and battled them, winning and thereby earning their respect. To symbolize their partnership, the great daitengu Sojobo placed a hand on Buzens back and transferred some of his chakra to him, creating a permanent small teal Tengu fan seal on his back just below his neck. This marking would continue to be passed down from Buzen to all future descendants. They also trained their clan in swordsmanship which is why many of the Tsubasa clan are skilled swordsman.

Years later when Kagerō Village was destroyed, Buzen foresaw the impending attack by Tanigakure and that it would result in their loss, to prevent the clan from being wiped out altogether, Buzen sent their strongest members away while the rest including himself stayed behind to fight and hold off the enemy as they escaped. The few survivors scattered to various parts of the world, most notably Kirigakure and Takigakure. But there are others in other locations.

Appearance
Common traits of the Tsubasa clan is tan skin and grey eyes, they also tend to have light brown hair, black hair or dark blue hair. Their choice in clothing depends on where they live at the time but they are commonly seen wearing haori as casual attire. Their clothing almost always being teal, green or blue in color. They're known for wearing silver or black feather accessories such as necklaces, earrings or hair accessories.

Sometimes they can also be seen wearing Tengu beak masks when going undercover or just as a fashion choice.

Their clan symbol is two black wings with a light blue diamond in the middle, the black wings representing their name and the Tengu they summon, and the blue ice shard in the middle representing their clan's  Ice Release kekkei genkai.

All descendants of the first clan leader Buzen are born with a small teal Tengu fan birthmark on their back just below their neck.

Senrigan
The Tsubasa clans Doujutsu, the Senrigan (千里眼 literally meaning 'clairvoyance') nicknamed 'wing eye' (羽眼 Hanegan literally meaning 'feather eye') by enemies who've seen it based on its appearance, their eyes change to a teal color with 2 white feathers resembling ones from angels wings.

This doujutsu is a kekkei Genkai known only within the Tsubasa clan. Because of the doujutsus many drawbacks, it is rarely ever used except in dire situations, making it largely unknown within the shinobi world. The biggest drawback is that the user goes permanently blind after using it for the first time which is irreversible. However, they will regain their sight anytime they use it afterward but will return to being blind once its deactivated.

This doujutsu's abilities grant the user a sense of clairvoyance, allowing them to see briefly into the future making them able to easily anticipate what the enemy's next strike will be and how to counter it. They can also sometimes see their comrades death which allows them the chance to prevent it or warn them in advance, depending on how developed the Wing Eye is, be it the beginning stages or more advanced determines how far their precognition can see ahead

In the beginning stages they can usually see only a few seconds ahead but when fully matured they can see several minutes ahead or farther depending on the strength of the user, besides clairvoyance it also allows them the ability to sprout wings made of chakra much like the Akimichi's butterfly mode but instead of butterfly wings their Tengu wings and are usually white, black, blue or teal in color and are usually small to conserve chakra, but can be made bigger the more chakra is added to them, which wouldnt be ideal since it would drain their chakra faster. These wings allows them to fly and launch aerial attacks more effectively giving them the advantage over most enemies

With the Senrigan they can see even in the dark and perceive the enemies aura making it nearly impossible for them to hide even if they have no physical form or make themselves invisible. Even suppressing their chakra would not prevent them from being spotted as the Senrigans Aura Detection can still pick up malicious intent, fear, or other intense emotions. However, if the enemy can suppress their chakra and numb their emotions or use Aura Concealment, only then can they elude them, but because the Senrigan is so unknown amongst the shinobi world it'd be impossible for the enemy to know this weakness, unless they were already familiar with the Tsubasa clan.

Because of the Senrigan causing permanent blindness after its use, the clan has branded it a forbidden jutsu Most of the Tsubasa clan are born with the potential to awaken the Senrigan, but not everyone in the clan can awaken it, to awaken the Senrigan you need to meet 3 requirements To be continued

Nature Transformation
The Tsubasa clan is highly proficient in both water and wind-natured chakra to create Ice Release. They are able to utilize it to perform special techniques and cause devastating damage or defend against projectiles or a barrage of attacks. They are even able to defend against explosives, however a strong enough explosive such as one from Explosion Release can damage or break through the ice. But because of some of the clan fleeing to The Land Of Water and keeping their identity a secret to avoid persecution, they could not openly use these techniques.

Intelligence
The Tsubasa clan also has some skill in medical ninjutsu, although very little they are able to use the mystical palm technique and chakra transfer to quickly heal their allies. However the more severe the injury, the more chakra is required to heal them. They are also knowledgable of many poisons and medicinal herbs. They are especially useful during war as they are able to discern which allies are still alive.
