Tetsusaiga!

Story: The Tetsusaiga was a sword forged by the swordsmith Toutousai. It was forged from the fang of Inutaisho, (Inuyasha and Sesshomaru's father) He used the sword to protect his wife & then infant son Inuyasha. The sword has the power to transform and become bigger. When he died because Inuyasha was too young to weild a sword, he hid it inside his grave and the only means of getting to the grave was through the Black Pearl; (hidden in Inuyasha's right eye). When Sesshomoru finally got to Inutaisho's grave it turned out the tetsusaiga had a barrier so a demon like Sesshomaru could not touch it. On the other hand humans could but they can not make it transform (thus making the tetsusaiga a ussless sword) But Inuyasha Being half demon & half human could hold and use the tetsusaiga to it's greatest power (obviously the Tetsusaiga was meant for Inuyasha). But Sesshomaru also gets a sword called the tenseiga which has the power to heal (we will talk more about that at the Tenseiga page later) But Sesshomaru not being kindhearted had no use for it but he had incredible strength on his own, (as Inuyasha was a weaker half demon who needed the Tetsusaiga to defend himself). so with Inuyasha's Tetsusaiga with it's powerful attacks and Sesshomaru's invincibility it was feudal for the two half brothers to fight against one another! Tetsusaiga's Attacks: Wind Scar: The wind scar is Tetsusaiga's most well known attack. This attack has the power to slay 100 demons in one swipe.   Backlash Wave:  It works by ensnaring the opponents attack in the windscar and firing it right back at them. Red Blade Tetsusaiga:  This Type of attack isn't really an attack at all, but more appropriately a technique. It allows the user to "slice" through most types of spiritual barriers.   Adamant Barrage:  When this attack is used the entire blade of the Tetsusaiga becomes covered with shards of metal. To use this attack one must swing the blade in the direction of the enemy. The shards of metal then spray in that direction. Dragon Scale Tetsusaiga:  This technique is by far the most dangerous for InuYasha to wield. The first time he used it, he burned his hands. The Dragon Scale Tetsusaiga allows the user to absorb demonic energy. Because of this, the hilt of InuYasha's sword became exceeding hot , thereby causing the afore mentioned burns.   Meidō Zangetzuha:  The Meidō Zangetzuha is an attack that when used creates a pitch black portal to the nether realm & sends any one unlucky enough to get hit by it to said realm.
