The Kentora Clan
The Kentora Clan resides in the Land of Fires dense forests. Members of the clan can be trademarked by having an peculiarly yellow iris (AKA: yellow colored eyes). Generations of living in near jungle like conditions has caused the clan to portray predator-like methods of combat: silently stalking opponents or prey, and then swarm in chaotic yet strategic patterns.
Due to the density of the near jungle like conditions, the eyes of the Kentora Clan have evolved into an ocular Dojutsu: giving rise to their yellow iris.
The Yomegan or The Night Eye (I understand its improper Japanese....).
Upon activation, the slits of the Kentora clansmen turns to slits like that of a cat. The Night Eye grants the user the ability to see perfectly in the dark. Their ability to track and perceive fast moving objects is also increased. Yomegan users can also see scents as visible trails of smoke or dust. Allowing them to analyze patterned guard paths or stalk prey. The final ability of the eyes is to endure an adrenaline rush. Granting the Kentora clan members above average reflexes, speed, and strength... Though no where near the level of people such as Tsunade or SM Naruto in terms of strength.
Though the rivalry no longer exists due to generations of being separated, the Kentora Clan were once bitter rivals to the Inuzuka Clan. During allied conflicts, the Kentora Clan would typically ally themselves to the Uchiha and Aburame Clans while their Inuzuka rivals stood beside the Senju and Sarurobi Clans.
In terms of appearance, the decently vary in overall appearance. The most similar appearances are delicate yet fit appearances, yellow eyes, and Brown hair with an under layer of a blond highlight. Typically their hair length runs just past shoulder length.
However, on occasion, gifted members of the clan are born with black hair, and a underlying white highlight. Such members have proven themselves to be elite shinobi in all cases.
