Mitama

Mitama (御魂・御霊・神霊, Honorable Spirit) is a technique created by Reikon after mastering his Shisoku. It is considered a more refined version of the technique due to the extended range and increased speed.

Usage
Being the son of Genma Shiranui, Reikon inherited some of the former's traits, such as the signature senbon in his mouth. Inspired by this, Reikon would apply that trait into his fighting style. By imbuing the senbon with his chakra whilst in his mouth, he would expel it as a projectile, just as Genma did, with instantaneous speed. This small needle was powerful enough to pierce through flesh and even metal. Once making contact with the opponent, the chakra doormant within the small senbon would be triggered, creating the same effect as the Shisoku, albeit at a faster rate.

Once it makes contact, the target's soul is separated from their body and then transported to purgatory, leaving nothing but a corpse in the real world. This technique had been disputed to be a sealing technique, however, as there are no special seals involved, it is noted to incorporate space-time ninjutsu.
