Spiral Pill is a powerful endurance skill commonly used by Naruto Usagi, the protagonist of Japanese anime Naruto. It was developed by Namikaze Minato, the fourth generation of Naruto, inspired by Bijyudama and took three years. His son Naruto Uzumaki carried it forward. Like Bijyudama's principle, chakra is concentrated in the hand, condensed in a small range, destroyed the enemy with the huge tearing force generated by high-speed rotation, formed a palm-sized chakra ball, and then attacked the opponent's skills. Once you hit your opponent, it will not only cause superficial damage to him, but also temporarily cause chaos in enemy chakra. Of all the ninja techniques that don't need seals, spiral pills are the most powerful. This is an amazing endurance and will grow with users. (The Book of Arrays)
