Renkotsu

An agile strategist and explosives expert, this brilliant second-in-command of the Shichi'nintai utilizes advanced metallurgy and artillery to dominate the battlefield. Though initially a loyal subordinate, the corrupting influence of a Shikon Jewel shard fuels a growing resentment toward his leader. Driven by a desperate desire for immortality, his growing arrogance and thirst for power eventually lead to a fatal confrontation with Bankotsu, marking a tragic end to his pursuit of supremacy.
