Vajrayāna

Vajrayāna is a technique created by Hiroko Kurogane sometime after becoming an ANBU captain.

Overview
Hiroko channels a large amount of fire chakra into her Chakra Enhanced Triple-Bladed Claw. The concentration of chakra flowing through the blades causes them to radiate with heat, to the point that the weapon glows white. When complete, it can be used to slash, impale, or sever limbs, the technique's thermal energy drastically increasing the cutting power of the weapon, to the point where little-to-no kinetic energy is necessary. This produces heavy amounts of damage that is usually fatal.
