He is then fought in chapter III where it is helped by two other Glamors. after its defeat, it try to attack an Bayonetta with its projectiles while she is trying to catch a falling Loki. It is also fought as a mini-boss during the Jetfighter Assault portion of chapter XVI. Once it is defeated in chapter III, its card will be unlocked in the Tag Climax mode.
Hierarchy of Laguna
"Glamor, as a First Sphere Seraph, rests at the highest rank in the angelic hierarchy. Seraphim are the closest beings to God in existence and cannot be seen by humans in the physical world under any circumstances.
Yet, since the dawn of history, there have been discoveries of statues depicting a six-winged snake traversing the heavens. Most likely these have some connection with The Book of Revelation, written by a Lumen Sage and found in the scriptures of Ithavoll.
Of course, this means there must have been a sage capable of connecting to Paradiso and conversing with Glamor through spiritual means."
