Kyo didn't sleep the night before the ceremony. He bound his hair back in a tail to keep it out of the fire. He spent the hours tempering the weapon, before he began working the blade over a stone. Kyo maintained this process until the edge of the blade was hidden from sight by just how thin it was. He had decided last week to forge a kunai for every member of his squad just a small thing for each to carry the kind of weight that they carry with them not just their own life but the life of their teammates. The problem was it takes Kyo 2 days to make one kunai. So he had to get the last kunai finished. He decided last minute that he needed to do something to make them more than Yoru kunai. He redid their bindings in a red and wrote in black. "Guardian"
While he was all prepped to do forge work he went ahead and began working on his own weapons. First he got out Akuma no Kiba and began working the stone over the edges just feeling the layers of metal falling away to create the new edge. Kiba never got much real use, therefore it was finished quickly. He resealed the scythe in its scroll and set it to the side. He brought out the sword his uncle had given him as a graduation gift. It was a weapon that had seen its share and then some of battle in the resistance. And this was the first time he had taken the time to work the blade into the proper condition. The sword was heated and fused with some new iron and the process of hammering, tempering, and sharpening this went on until he lost himself in the work the metal speaking to him. He maintained the work until one of the forgemasters stopped him reminding him he had a ceremony to be at. After being startled awake he looked and saw the blade was back in the proper conditioned it could use another round of tempering and sharpening just to perfect it.
He took the kunai he had made for himself and cut his hair free of the binding. He left that moment his arms covered in soot from the forge, he wasn't wearing his normal clothes that most of his fellow academy graduates saw him in. Now he was wearing a formerly white Tee-shirt and grey pants. He wasn't wearing his jacket. His sword hung at his side. He arrived at the location in time to see the hokage vanish. So he was standing there with no idea who his team was and so he stood there lost among the people.
