Frog Kata was somewhat like taijutsu, but in reality, it was Sage Jutsu because it required the use of Natural Energy.
The greatest difference between Sage Jutsu and ninjutsu was the use of energy. Sage Jutsu required Natural Energy, and its effects often produced extraordinary results.
Naruto and Hinata were practically pressed together. They struck at the same time, each drawing Natural Energy from their surroundings and unleashing Sage Jutsu: Frog Kata.
The Fourth Raikage was greatly startled. His instincts told him that although Naruto and Hinata's move appeared plain and unremarkable, it concealed deadly danger.
The Raikage took a step back. At this distance, they shouldn't be able to hit me.
Sure enough, Naruto and Hinata each threw a punch, and both of their fists missed.
Suddenly, fist marks appeared on both the Raikage's left and right cheeks, and blood sprayed from his mouth.
Frog Kata was Sage Jutsu, so its effects could not possibly be so simple.
By using Natural Energy, Frog Kata's attack range had increased, and its power had likewise been enhanced.
To the naked eye, Naruto and Hinata's fists had missed, but in truth, both punches had landed solidly on the Raikage's face.
Naruto's fist struck the Raikage's left cheek directly, while Hinata's fist smashed into his right. Their fists hit simultaneously, squeezing the Raikage's face inward from both sides.
The Raikage was sent flying a great distance, losing two teeth as he lay motionless on the ground.
Naruto frowned. Although we hit him, with this guy's physique, this can only count as a minor injury... No! It might not even count as a minor injury...
Naruto had guessed correctly. The Fourth Raikage had taken two Sage Jutsu Frog Kata strikes at once. An ordinary person would have long since been unable to endure it.
