Arashi's Hidden Jutsu

After stealing a Hiden Jutsu scroll from an unknown village, Arashi gained several Hiden Jutsu. He makes great use of these Hiden Jutsu in battle.

Iron Armor Technique
As for his Hiden unique to himself, he has the ability to re-arrange the configuration of carbon atoms of his body, allowing him to convert his skin into Tempered Steel. He usually uses this ability to partially strengthen the density of selected parts of his body during battle, but can extend the effect to its entirety. In this form, he resembles a black-skinned demon with a malevolent facial visage. As Arashi has control over the configuration of his body's carbon atoms, the substances that he can convert his skin into can vary based on his intentions. Though he prefers to use his Iron Armor to form claws covering up to his shoulders (thereby summoning make-shift weapons at will), leaving much of his body vulnerable to attack (only using his shield on other areas to protect them from attack temporarily, as seen when his brother attempts to slice Arashi's head off with his sword only to have it broken in two by Arashi's armor).

Weapon Blood Technique
By first activating his Iron Armor technique, he has the ability to control his weapon blood to produce blades from numerous from his limbs but the parts of his weapon form will disappear when his chakra is depleted or the jutsu is givin up. While he is under the influence of the Refined Madness, his fighting is relentless towards his target and can make use of his form in various ways like an expert weapon user and can be considered comparably better than certain members of the Seven Ninja Swordsmen of the Mist.

Sanzu Halo Technique
A technique which when not active absorbs large amounts of chakra around him. When released it looks as if there was a glowing white halo around Arashi's head. This increases his chakra exponentially along with speed and power. In this form his power is increases exponentially, as he can crush a large beast with one stomp kick. He also gains two lines around his wrists that allows him to create chakra blasts that can cut through an opponent. This mode however does deplete Arashi from mostly all of his chakra leaving him defenseless after using this.

Refined Madness Technique
Arashi uses this technique to go into a state of mental madness. In this state he claims to shut off his brain and let his pent up anger surface, which allows him to go crazy. it is unknown if this actually a technique or just an excuse for him going crazy temporarily. However, this technique does not come without risk, as the capability poses the significant potential of resulting in Arashi becoming consumed by the very emotion he desires to exploit, losing himself in the depths of madness and committing atrocities he would never normally consider.
