Kishin Hunter (Kishingari, anime version) is a Soul Resonance technique in the Witch Hunt series of scythe resonance attacks. It is only present within the Soul Eater anime, and has not made any appearance in the manga. It is possibly the most powerful form a scythe-weapon can assume.
It is unknown what the attack's capabilities are, but it can be assumed it is effective in killing immortals like Kishin Asura, as Shinigami managed to use it to completely sever one of his arms. With it, Maka was able to cut into Asura's torso, but it still proved ineffective, as he shattered the technique and healed his injuries quickly after. Like Majin Hunt for Maka, the attack carries her Anti-Demon Wavelength though Asura claimed it didn't kill him because he is the embodiment of madness and madness itself not inherently evil or impure as everyone has it.
