When Yamato notices the lightning unexpected extend towards him. He quickly judges it's trajectory, and with his already extended hand, he blocks it with his Rakiri. As the two jutsu's collide, Yamato quickly smirks, and does a single handseal and channels more chakra into his Raikiri, extending it. He transforms his Raikiri into a powerful lightning spear which extends and overpowers the kids jutsu, piercing his chest and killing him.
