Xiphos

Xiphos is a weapon of pure energy created from the Fusion Chikara, Valor. Xiphos has the appearance of a double-edged shortsword that can cut through any material, including voidstone. Throughout the storyline, Xiphos progressively grows longer depending on Kazega's current energy level, being around a foot in length when he faces off against Akuma-Ara.

Xiphos completely fuses with Kazega's arm when Ayama merges with him, gaining infinite destructive potential. However, the power gained in this state is so great, barely a single swing is enough to completely exhaust Kazega's energy reserves, but the swing is enough to subdue Akala.
