Shisoku

Shisoku (死觸, Death Touch) is a powerful, yet simple technique, employed by Reikon. Due to the magnitude it carriers, there have been disputes of labelling it a Kinjutsu.

Usage
By forming brief contact with the target, the user can mentally trigger an instantaneous distortion in space-time, whereby the target's soul is separated from the body and sent to. Within this realm, the user obtains a physical form, however, their body and chakra remain in the real world, and thus escape is rendered impossible. Reikon can perform the technique whether in his normal form or spirit transformation, however, with the latter, the technique is twice as fast. Additionally, the user can harness the target's abilities and knowledge by entering its body and literally absorbing it to its very being.

Drawbacks
The user becomes haunted with nightmares of the person whom the technique is used on for an entire week, however, that is erased once the user gets used to such. This technique also causes tunnel vision for a few minutes, and thus users must rely on other senses for enhanced vision.
