Yaegotoshironushi-no-Kami, the ocular technique of the Ōtsutsuki Kuangshi, along with his awakened Shikigami, could manipulate the power of "Word Spirit"!
During the battle in Jianzhou Country, he had used it before. Later, Kuangshi was defeated by Sasuke Uchiha, leaving behind a "Karma" before his death!
As the Karma was deciphered, Sasuke Uchiha also gained Kuangshi's power and acquired the Shikigami power of Yaegotoshironushi-no-Kami!
Those who believed in Word Spirit believed that words contained a force not to be underestimated, with vows and curses serving as examples of its application. Nonbelievers thought it was merely self-hypnosis, or an unconscious means of driving believers to act."
But Word Spirit truly existed. It was another mysterious power beyond Chakra. The Sage of Six Paths had once dabbled in the power of Word Spirit, creating the three ninja tools known as the Golden Canopy Rope, Seven-Star Sword, and Crimson Gourd."
In later generations, the Second Hokage, Tobirama Senju, had also researched Word Spirit. To prevent ninjas from going back on their word, he created the "Tongue Seal of Womb Eradication." If a person who swore an oath violated it, the curse would be engraved into the bloodlines of his descendants, resulting in the extinction of his family and the destruction of his household! After creating it, this was also the only curse technique that even Tobirama himself considered inhumane enough to seal away voluntarily!
But all of the above was merely a portion of Word Spirit's mysterious power, already the limit of what the Ninja Sect and ninjas could reach."
The true power of Word Spirit was the true power of Yaegotoshironushi-no-Kami!
Rustle, rustle, rustle...!
Golden bird feathers drifted down from the sky!
Garuda stared fixedly into "Sasuke Uchiha's" eyes. "So that brat Kuangshi's power was obtained by you, brat!"
