Banryūsen

was a technique that was acquired by Bankotsu's sword Banryū after being embedded with Shikon Jewel shards.

By channeling the energy of the Shikon Jewel shards, Bankotsu could use an attack that was almost identical to Inuyasha's Kaze no Kizu, with the only major difference was that it was pink in color, but was equal in terms of power.

Bankotsu used this technique when he battled Inuyasha at Hijiri island after the purifying barrier disappeared and allowed Inuyasha to use the full power of Tessaiga.
