Heat Blast

was a technique that was acquired by Bankotsu's sword Banryū after he gained the seven Shinkon Jewel shards from his fallen Shichinintai.

By channeling the energy of the Shikon Jewel shards, Bankotsu could unleash a blast of heat that was identical to Inuyasha's Kaze no Kizu, with the only major difference was that it was red-orange in color.

Bankotsu used this technique in his final fight with Inuyasha in the caves of Mount Hakurei. His Heat Blast countered Inuyasha's Kaze no Kizu several during the battle, making their techniques evenly matched.
