Tōkijin

Tokijin(「闘鬼神」, lit Demon Fighting God), was a sword forged from the fang of Goshinki a offspring of Naraku, was wielded by the daiyokai Sesshomaru.

History
Sesshomaru abandoned his quest to obtain Tessaiga, but instead searched for a sword that could rival it. He discovered the remains of the oni Goshinki who was able to break Tessaiga with it's own fangs, Sesshomaru having discovered this decided that the fangs would produce a powerful sword that could rival the Tessaiga. He requested the swordsmith Kaijinbo(a former apprentice of Totosai, but was exspelled for creating too many evil swords) to create a sword from Goshinki's fangs. At first Kaijinbo refuses because he cannot create a great sword from a dead yokai, but Sesshomaru revives him with the Tenseiga, at which point Kaijinbo gladly accepted his request.

Upon completion the Tokijin possessed Kaijinbo and he killed Jaken who was checking on the swords progress. Goshinki's hatered for InuYasha was so great that the Tokijin also bore the hatered, the Tokijin forces Kaijinbo to go after InuYasha. Kaijinbo was not strong enough to bare the Tokijin's great power, so when he battled InuYasha who weilded Tessaiga his body was destroyed by the pressure of the two blades. Sesshomaru(who revived Jaken and to discover what happened to the sword) finds the Tokijin and claims it, defeating the evil aura that possessed Kaijinbo. Sesshomaru uses the Tokijin to test the sword and discover the change in InuYasha's blood. The Tokijin was able to match Tessaiga in power and gives Sesshomaru the advantage in the battle(The reforged Tessaiga to heavy for InuYasha to wield). The battle ends when InuYasha transforms into a full yokai and his friends escape with him, while Totosai distracts Sesshomaru.

Signature Weapon
After the battle Tokijin becomes Sesshomaru's signature weapon. Over time Sesshomaru's mastery of the sword reveals the true power of the sword. Originally Tokijin fired needle Kenatsu that cut the enemy without the blade actually touching them. Tokijin developed a stronger Kenatsu that release a powerful energy wave made of yoki, the attack is similar to the Kaze no Kizu. In the InuYasha movies series Sesshomaru can channel a large amount of his yoki into the Tokijin to release the Soryuha which rivals the Backlash Wave, the technique is not used in either the manga or the anime meaning it is not canon.

Because the Tokijin was forged from the fangs of a oni it limits the amount of yoki Sesshomaru can release. After the Soryuha is used the Tokijin cannot be used until recharges. Tessaiga and Tenseiga being forged from a daiyokai's fangs they do not have this limit.

Destruction and Replacement
When Sesshomaru battles Moryomaru for a second time he insults Kagura infront of Sesshomaru, which angers him. Sesshomrau unleashes the most powerful yoki wave ever produced by the Tokijin and damages Moryomaru's shoulder armor. He pushes the Tokijin into Moryomaru's armor and cracks it, but the stress applied to Tokijin breaks the sword.

Sesshomaru refuses to get Tokijin repaired because it did not have the power to defeat Moryomaru and instead finds a replacement sword, which he eventually found when Totosei reforged Tenseiga into a weapon with a offensive new technique

Special Ablities

 * Kenatsu: is a special ablitiy that allows the Tokijin to cut a opponent without toching them. Tokijin fires a needles made of yoki which can pierce an enemy. The Kenatsu develops into a massive wave of yoki which is equal to the Wind Scar, Sesshomaru was able to produce a Kenatsu stronger than Wind Scar when Moryomaru angered him.


 * Soryuha: is a special movie series only technique. When Sesshomaru charges yoki into the Tokijin and then releases as massive amount of yoki in the form of blue arcs of lightning. In the fourth movie the Soryuha became stronger and took the form of a dragon. Soryuha is equal to the Bakuryuha but Sesshomaru can channel his anger into the Tokijin to strengthen the attack further, making the attack over power the Bakuryuha.
