Ichibei Hyosube's essence was "black." All the black in the world was his power.
In his battle against Yhwach over a century later, Yhwach's Altar of Usurpation merely took away Ichibei Hyosube's "black" for an instant. Then, all the black in the world returned to Ichibei Hyosube, restoring his power.

Likewise, the higher the rank of
