Yasaka Magatama

Using the complete form of Susanoo, the user is able to create the Yasaka Magatama between two of its arms, consisting from a number of magatama bound together through their respective centres by a thread of chakra. Due to this structure, the tools then act in a similar manner to that of a shuriken or simple projectile when thrown by Susanoo, rapidly spinning towards the intended target.

The technique can take on multiple forms ranging from three magatama being bound together by a single circular thread, after being created by the right arms of his Susanoo, or having a considerable number of magatama strung out between two of Susanoo's hands, using an interconnecting thread. These can detach themselves from one another, with each magatama becoming a separate projectile instead.
