By using his varying "releases" derived from Lightning Release, Kei can manifest Hell Stab (or Dual Hell Stab), with varying effects. Such as, creating one with powerful magnetic fields, that can transfer to those near it, or ones that use iron gold sand, or bright scale powder, among other things. He even has ones that induce radiation and heat, or ones that use his nanite powers. This creates a multitude of purposes, besides just piercing, or cutting, or shape manipulation, with or without chakra (due to his nanite capabilities).
