Hiramekarei: Kagutsuchi Unleashing

The user unleashes the sword Hiramekarei, by emitting a large quantity of chakra on either side of the blade, from the two holes located near its tip. The user then uses the Blaze Release ability to turn the chakra into black flames, then shaping the flames around it in the form any weapon the user chooses.

The flames cause great damage, rather than the weapon itself. The user can also make it a stream to incinerate the opponent.
