Hellfire Release

Hellfire Release is a unique ability possessed by a select few members of the original Kasai clan. By condensing their Fire Release chakra, these Hellfire users could create powerful crimson flames, capable of incinerating targets. What make Hellfire even more dangerous was its versatility. Almost any Fire Release technique could be converted into a Hellfire Release technique. There were a few techniques unique to Hellfire Release, but all posed great risk to the user. Many believe Hellfire Release to be the most powerful variant of Fire Release, until Amaterasu became more known.
