Born of a sage and his beautiful maiden, the Kuruko clan is nomadic and holds a very philosophical outlook on life. They often wonder about things in life that most take for granted, some elders meditating and pondering the same question for days on end, only to reopen their eyes with nothing to show for their intense concentration. The Kuruko clan used to be separated into four branches, each using specific form of metal, Gold, Silver, Steel, and Iron. During one of their wars, the Uchiha and Senju all but obliterated the clan, only the branch of Iron remaining. The clan would often wander, place to place, village to village, never finding a place to settle but forever seeking such a place to do so and to call "home." The elders are often depressed because of this, but the children find it fun and exciting running into a new adventure each and every day. The branch of Iron sought no vengeance on Uchiha and Senju because of the philosophical beliefs their elders held who made the decisions of the clan MUCH to the displeasure of the young members of the clan.

After the Fourth Shinobi World War, the Kuruko clan was all but extinct, not because of dying in battle, but because they feared venturing to any of the villages in this time of conflict and horror, fearing to be forced to fight or to be attacked. So, without going to other villages for resources or food, most soon died off, so many in fact that only about 50 members of the clan are left today. These 50 members for the most part split up, a small family here and there, some holding to the old beliefs, those of no war, those of peace. Most have changed. Most have went through enough pain to learn, to realize that if they do not fight to defend themselves, do not fight to gain, they will die off. So, while they still dislike fighting, the Kuruko clan does so for survival, intent on their clan prospering because of the individuals' achievements.

A few major drawbacks of this is the user can only manipulate iron of their own creation of of their own body, thus not able to redirect enemy projectiles. A second drawback includes, while it takes no chakra to actually manipulate iron as a passive ability, the user creates iron particles from chakra, so the more they need in a fight the more chakra they eat up. The Kuruko clan is not able to use iron dust/particles which are already materialized, thus eating up their chakra as a necessity. (Some bypass this by holding weapons or pouches of iron dust/particles that they have already created, using that to fight while slowly creating more so the stamina decrease isn't so large.)The third drawback is the user can only materialize their iron particles within a 5 foot radius of themselves, not able to form a weapon close to an opponent and drive it into their heart or other organ at point blank range. The fourth drawback is the clan can ONLY perform taijutsu or techniques related to their kekkei genkai, meaning no nature manipulation, no body flicker, no clones, and no genjutsu. These are just examples, but the clan can literally only perform techniques which are taijutsu or their kekkei genkai. However, as it is only a manipulation of chakra, a user can still perform a surge of chakra to break genjutsu.

Element: N/A
Range: 0-50 Yards, increasing the higher the rank of the user.
Specialty: Kekkei genkai
Duration: None
Cooldown: None, as it is passive
Description: The first and foremost technique of the Kuruko clan is their ability to manipulate iron particles. The user can use it in a similar fashion to Gaara's sand, simply manipulating it to strike and attack the opponent, or form it into a blade or some other sort of solid weapon. The downside to this is their can ONLY manipulate the iron of their body and the iron they create.

Range: 0-5 Feet
Specialty: Kekkei Genkai
Duration: N/A
Cooldown: None
Description: This is the ability of the Kuruko clan to generate Iron particles/sand from their own chakra, at a maximum of 5 feet away. While the chakra cost isn't much, using techniques like Gaara's Giant Sand Burial can exhaust the user easily.

Name: Iron Body Infusion

Rank: C Rank
Type: Supplementary
Element: N/A
Range: N/A
Specialty: Kekkei Genkai
Duration: 5 Posts
Cooldown: 3 Posts
Description: The third technique that the Kuruko clan uses to their advantage is a complicated one. The user manipulates the iron inside their blood, pumping the blood through their veins at extremely high rates, increasing the adrenaline in their system, increasing the oxygen flow, thus the user's muscles will react faster, move faster, and with a higher amount of strength.

Name: Iron Sight Infusion

Rank: C Rank
Type: Supplementary
Element: N/A
Range: N/A
Specialty: Kekkei Genkai
Duration: Indefinite

Description: The final ability of the Kuruko is a Dojutsu. Using the same method as above, the user does the same thing, pumping blood, adrenaline, and oxygen, except this time to the eyes and brain. In this, the outside world essentially slows, allowing time for reactions and granting the user the ability to see chakra.
