Chapter 15
The Sword of the Heavens, Tenseiga
Sesshomaru quickly sheathed Tenseiga and withdrew Toukijin before he lunged at Naraku and began clashing blades with the evil half demon. Sakyuamon soon followed suit and began trying to strike Naraku with her staff. Naraku was blocking each of their attacks without breaking a sweat. Naraku formed a second black lighting blade in his second hand, and while Blocking Sesshomaru and Sakyuamon with his right hand he blasted with a burst of energy from the left. Sesshomaru and Sakyuamon were sent flying and they landed beside Inuyasha. Inuyasha and the other quickly ran up to Sesshomaru and Sakyuamon. "Are you guys alright?" Kagome said with worry in her voice.
Sakyuamon stood up and dusted her self off as she said, "I've been in worse shape. What about you Sesshomaru? How are you doing?"
Sesshomaru stood up beside her and said, "You insult me with such a comment. Do you think a filthy half demon like Naraku can hurt me?"
Sakyuamon chuckled slightly as she said, "Of course, what was I thinking?"
Sesshomaru smiled and said, "Good, I'm glad you know who you fight beside. You don't fight beside some common forest demon. You fight with the lord of the western lands, Sesshomaru." Sesshomaru was about to jump back into the fray when he felt a firm hand on his shoulder. He turned to see Sakyuamon was holding him back.
Sakyuamon shock her head before she said, "Inuyasha, I need you to buy us a little time. I think I have an idea of how to beat Naraku."
Inuyasha nodded as he withdrew and transformed Tetsusaiga. He then leapt toward Naraku, the wind scar already forming around the blade, with Sango and Miroku close behind. Once Sakyuamon was sure they had Naraku's full attention she turned to Kagome and said, "When the time is right I need you to fire off one of your sacred arrows."
"What are you planning to do?" Kagome asked as she took an arrow form her quiver.
"I am going to see if we can combine the power of the Toukijin, the Tenseiga, your sacred arrow, and my spirit strike." Sakyuamon said as she released her grip on Sesshomaru's shoulder. Sesshomaru took that hint and with drew both the Toukijin and Tenseiga from there sheaths. He then turned his head toward Sakyuamon, ready for this plan she spoke off.
Sakyuamon nodded and said, "Okay, Kagome when Sesshomaru launches this attack you will need to fire your sacred arrow right behind it. This attack will not harm Naraku very much, but it will make him especially weak against anything that is filled with the power of a priestess." Kagome nodded her head as she readied an arrow in her bow. Sakyuamon then turned her head to Sesshomaru and said, "All right, our turn Sesshomaru. Do you remember earlier, when you placed the Toukijin and Tenseiga together the Tenseiga drew on the power of the Toukijin. If we can make it happen again I can add my power to the Tenseiga. By releasing all that power at once we should be able to stun Naraku and weaken his defenses to the point Kagome should be able seriously injure him."
Sesshomaru smiled as he crossed his two great blades in front of his chest and he began to draw the energy from the Toukijin to the Tenseiga. While this was going on Inuyasha, Sango, and Miroku were battling furiously with Naraku. Naraku was using his new black lighting swords to sword fight with Inuyasha with his right hand. While, at the same time, he launched a volley of black lightning at Sango and Miroku, keeping them from getting close enough to the fight to help Inuyasha. Sango had to use her Hiraikotsu as a shield to block the lighting from striking her. Miroku on the other hand was dodging the lighting, but could only dodge from side to side. He could not get close enough to strike Naraku with his staff and the use of his wind tunnel was not an option because of the poisonous insects in the area.
Inuyasha was unable to strike Naraku with the Tetsusaiga, but he finally tried something other then just swinging his sword around. He sliced at Naraku forcing him to block the attack, but then while both his hands were occupied Inuyasha balled his hand into a fist and punched Naraku right in the gut, sending him flying back several feet. He then quickly took hold of the Tetsusaiga with both hands and launched a wind scar attack straight for him. Unfortunately Naraku was able to block the power of the Tetsusaiga by summoning a barrier of black lightning. The barrier was unable to completely block the wind scar, breaking near the end of the attack. This made Naraku take the last force of wind scar which sent him flying into the court yard wall. Inuyasha was about to strike Naraku again when Naraku launched a powerful burst of black lighting right into his chest.
Naraku was already defeated though because as Inuyasha flew back from the force of the blast Sesshomaru finished draining the energy from the Toukijin and placing it in the Tenseiga. Sesshomaru then held the blade above his head and Sakyuamon began to pass her energy into the sword. The blade began to glow a dark blue that slowly turned white as Sakyuamon added her energy. When the blade was glowing a bright white Sakyuamon stopped feeding her energy into it and said, "Naraku, it is time to purify the world of your evil power."
Sakyuamon then launched her spirit strike attack and the four fox like spirits grabbed Naraku around his feet and hands, binding him and raising him up into the range of the attack. Sesshomaru began to bring the blade down as he said, "Naraku, you will not see the sun rise, DRAGON HEART STRIKE." Sesshomaru released all the energy contained in the Tenseiga and it hit Naraku right in the chest, and just as planed Kagome's sacred arrow came up right behind the Dragon Heart Strike and destroyed Naraku. Make that everything except Naraku's head which somehow survived the attack. Suddenly an explosion of Miasma engulfed the Castle's courtyard and in the confusion Naraku, the castle, and the courtyard walls turned to dust and disappeared from sight.
