The party of Sound ninja hit Team 7 hard. Kakashi immediately powered up his Thousand Birds and charged the jounin leader while Sakura had her hands full with, frankly, bits of Sai. Naruto knew she would keep him alive but he needed to end this fast. His hands flashed through a series of hand seals while he shouted "Grand Fireball Technique" at the top of his lungs.
The response was predictable. The enemy nins hastily used Body Replacement and before Naruto got to the last seal were safely behind tree trunks that would absorb the blast of flame. That was when Naruto's Great Breakthrough crashed into those trees, uprooted them and crashed them into other trees. The lone jounin stared at the mangled remains of his team for less than a second before Kakashi stabbed him with a kunai.
"What?", Naruto said in response to the questioning looks. "I can do Great Breakthrough without seals so I just flashed some random ones. And why are ninjas shouting their moves at the enemies anyway?"
