As One: Wind Scar!
Sango sat with Miroku's head in her lap. He was warm to the touch but didn't seem any worse. She looked up and watched the fight; it wasn't going well. Kuromaru was steadily attacking with his sword and Inuyasha's wound made him slow, just barely able to deflect the hits. Kagome was ready to shoot but didn't want to chance hitting Inuyasha. Since there wasn't much more she could do for Miroku, she decided to go help her friends.
"Shippo, I'm going to help Inuyasha, please keep a close eye on Miroku."
"Sure Sango." He watched as she gently kneeled by Miroku and kissed him on the lips. "Wow!" He whispered to himself.
Sango was still sore from her earlier tussle with Kuromaru but she wasn't going to let that stop her. After retrieving her hiraikotsu she moved closer and began looking for a chance to help. There!
Kuromaru brought his sword down hard and knocked Inuyasha back a few feet. Kagome ran to him, he was flat on his back breathing heavily. Hurriedly she helped him to sit up.
"Damn him," He whispered as he leaned back against Kagome. Inuyasha didn't think he could take much more but somehow he had to, had to protect the others but Kuromaru was already rushing towards them and he was still sitting.
The hiraikotsu swung around Kuromaru stopping him long enough for Kirara to knock him flat to the ground. She jumped off quickly and returned to Sango's side.
"Kagome! Help me, hurry!"
"What do you want me to do?" She knew they didn't have much time. Kuromaru's rage could be felt all around them.
"The wind scar is our only chance. Help me hold the tetsusagia. My right arm is useless but with you helping me, it should work. I need your strength Kagome." Inuyasha looked her in the eye showing his trust in her ability to help him.
Kagome wasn't sure it would work but seeing his belief that the two of them could bring out the full power of the sword, made all the difference. No doubts lingered as she went about helping him to sit up more. "We can do it."
Inuyasha flashed a quick smile then moved so that she could wrap her arms around him and bring her hands under his on the sword; together they held the tetsusaiga.
Kuromaru raised himself to his knees and looked up. His face was no longer handsome but distorted. His eyes glowed red and his claws and fangs had grown. All around his body was a visible cloud of miasma.
"That… is…it! Your end has come!" Completely ignoring Sango, eyes focused on the man and woman before him, Kuromaru launched himself towards them.
"Now, Kagome!" They brought up the tetsusaiga and Inuyasha called on its power. Kagome could feel the power surging through her, it was a rush. She felt invincible, like nothing could stop her, certainly not the demon before her. Kagome's hands and arms thrummed, now she could understand a little better why Inuyasha enjoyed fighting. This feeling of power was intoxicating. She was so in tune with Inuyasha that they spoke as one. "Wind Scar!"
Kuromaru was too intent on his vengeance to be aware of what they were doing and realized to late that he was going to die. The sword's power slashed across the ground and in a great flash of light, engulfed Kuromaru. His screams echoed in their ears as he met his end.
High up in the trees, out of sight, a saimyosho took in the scene, turned and headed back to Naraku.
Inuyasha's head dropped to his chest and he sat still. Kagome released the sword and hugged him. Her face against his she kissed him. "We did it, together."
"Yeah, the two of us."
