Kuzame looked at the two sharingan eyes he had put in a jar with water. He grinned so that his face was broken up in a grotesquely shark like smile and he looked at Hayate, the man from whom he had taken the eyes and who now was tapped on some of his blood. To take his eyes without hurting them was no problem for Kuzame and his ekiseigenkai,
but the drawback was that Hayate had suffered such a horrible pain that he had shouted so his vocal cords had break. O well Kuzame did not really saw it as a drawback it was just a bonus to hear him scream as he loved to hear people screaming in pain. Hayate who was now deathly pale because of blood lust hanged limply in the chain when Kuzame picked up a small bowl that was filled with blood and looked at the hole he had opened in the wrist at Hayate and closed it with his ekiseigenkai, leaving it as it was before.
Naraku wanted Hayate alive, Naraku had boasted about his fake plans, which Hayate then would tell the others, if he was found. Kuzame grinned at the idea, that's why he liked Naraku, who was playing so simply with human lives,
As Kuzame had been promised by naraku, he began to drink the blood in the bowl, which was starting to redesign Kuzame's body so he could take in sharingan. After a while he held his hand in front of him, grinning as he got one of his eyes to fall out and down in his hand. He softly put the eye in a glass jar and then picked up one of Hayate's sharingan eye and put it in the now empty eye socket, and did the same procedure with the other eye.
He stood there a while, with his eyes closed, while his ekiseigenkai worked to adapt the new blood line to his body. After a while he suddenly opened his eyes and looked up towards the ceiling with his new eyes sharingan eyes and a heavy gurgling laughter echoed through the dark and stony corridors
