Gracious & Glorious

Gracious & Glorious are first sphere seraphim which are on the top of the hierarchy of Laguna, the chain of command of the Angels of Paradiso. They are two humanoid Angels with enormous claws. They are said to have god-like powers and stand amongst the strongest Angels, they never appear to regular humans. They are also immune to Witch Time.

Bayonetta
They first appear in chapter X where they are fought as a duo. They then appear one more time in chapter XV.

Hierarchy of Laguna
"Within the nine ranks of the angelic hierarchy, the highest ranking Seraphim are charged with governing the love and zeal for the Creator. The pure white armored Gracious and the black armor-clad Glorious are often sighted in pairs; however, their existence itself remains legend, subject to rumors of varied veracity.

Supposedly gifted with incredible god-like powers, there are no records of Gracious or Glorious appearing on the battlefield of evil; however, it is said this is because a mere taste of their power is enough to destroy the world, devastating all its path - both the record and the record-keeper."

Trivia

 * Gracious and Glorious are the only angels not to be introduced via a cutscene, this is due to schedule restrictions, for the same reason, Gracious and Glrorious were modeled directly, and no design sketches of them exist.
 * Unlike their weaker counterparts, Grace and Glory, Gracious and Glorious do not wear masks. Instead, they have humanlike faces.
