Yachihoko

Yachihoko is a Mangekyō Sharingan Dōjutsu technique

Overview
Tied to the usage of her Engraved Tsukuyomi, it allows Nanashi to control the minds and the chakra of any individual linked with an Engraved Tsukuyomi branding. Yachihoko is a powerful Genjutsu, and works by erasing the memories of any individual it targets, creating puppets that Nanashi is able to manipulate. The Genjutsu itself is powerful enough that even a perfect Jinchūriki, such as Naruto Uzumaki, was unable to have it dispelled by his Tailed Beast, Kurama.

Yachihoko also allows for the manipulation of chakra from to and from the user via those marked with the Engraved Tsukuyomi blemish. Merz was able to absorb the chakra of a vast portion of the Shinobi World using Yachihoko. Additionally, Nanashi could transfer chakra this way, giving it to Boruto on two occasions to allow him to fight.

Influence
Like other Mangekyō Sharingan techniques, Yachihoko takes its name from ancient Japanese myth and the Shintō religion. Yachihoko-no-Mikoto being a god of luck and victory in sports and martial arts.
