After a while kusaki and Darlin stood facing each other, both using their Durzingun to create handsigns at the exact same time, building their chakra at the same level at the same time...

Naruto, sakura and the others were folowing kiba, "wait, I see something!" said Neji using his Byakugun he took lead next to kiba, and they both went straight towards the forest where the Fusion was about to occur.
After a while of moving through the trees, they all stopped as they found the person they were looking for, "we have to take him back!" yelled Naruto, but before they got close to kusaki and Darlin, a clone came out from behind a tree and blocked the way. "Naruto, don't get in the way, I'm trying to fix my problem, this is a jutsu to fuse ourselves together and become one, this is what happens to all who are from the Endo Shade clan, their Durzingun works against them until they learn to control it, but because I was too young when the Durzingun was awakened in me, I couldn't control it, and orochimaru tested his sick experiments on me, this made my Durzingun take a physical form, Darlin, but now we both decided to do this jutsu to fuse ourselves together." suddenly there was a flash were the jutsu was in progress! "It is done" the clone said and disappeared in a puff of smoke, and from the smoke created by the jutsu, emerged kusaki, who looked at the search parties and said "it is done, we now must go back to the village. Naruto smiled at Kusaki, as kusaki smiled at him.
