Harmony

Harmony are second sphere dominions which are on the fourth rank of the hierarchy of Laguna, the chain of command of the Angels of Paradiso. Harmony is a constantly flying angel with no legs, multiple wings and a long tail. Harmony is said to be the "symbol of peace" tasked with the defense of Paradiso itself and synonymous of control, sovereignty, and governance. They mainly attack with electricity, its tail and its claws.

Bayonetta
They are first encountered in Chapter V where multiple of them are fought just before Grace & Glory. They often appear in group after this encounter and are also often helped by other Angels.

Hierarchy of Laguna
"Within the Second Sphere Dominions, whose name imparts feelings of control, sovereignty, and governance, the angels named Harmony stand as a special symbol of peace.

When appearing in our world, it is said that humans experience their presence as an aurora-esque light; however, when viewed from Purgatorio, one would see Harmony embracing humans within their outstretched, fin-like wings.

Often pictured holding a trident and floating through the skies, Harmony are tasked with the defense of the heavens, even within Paradiso itself."
