Kongōsōha (金剛槍破, Adamant Barrage, "Diamond Spear Blast") is a special attack that launches shards of diamond (known by the more archaic term adamant in the Feudal Era). The technique originally belonged to Hōsenki, who passed the technique on to the Tessaiga after its user Inuyasha proved his worth by choosing to save his friends over strengthening his sword.
