Lucifer, Michael, and Raphael Morningstar

Raphael is an archangel older than Lucifer but younger than Michael, and is their brother. He is also the chief physician in all of Heaven, well-versed in medicine, but is also a warrior and can match Michael in strength. Raphael is aloof and serious, but despite his coldness, he loves his brothers, though he doesn't show it. He dresses in the same clothes as Lucifer and Michael, but instead of red or blue patterns, he has gold ones, and his eyes are pure black. His skin is pale, and his hair is the same as his brothers', about shoulder-length.
It also has three wings on each side of its back: first come the normal wings, then, a little lower, smaller ones, and, lower still, even smaller ones. On the outer side, its feathers are white, on the inner - golden.
Raphael also has a peculiarity that he himself does not notice: in a sleepy state, he cannot control his emotions, so from a cold and detached archangel he can become soft and caring.

Michael is an archangel, the first of the archangels created by God. He is
Commander-in-Chief of the heavenly armies and five other archangels, a legendary warrior and the greatest of God's angels.
Leader of the Seven Heavenly Virtues, the Archangel of Humility, who has the closest divine connection with God and acts as His sword and shield.
Lucifer's twin brother (fraternal, not identical twins), and also the uncle of Lucifer's daughter, Charlie.
Role in the plot
Mikhail leads an army of exorcists who descend into Hell annually to conduct purges—exterminating demons and preventing their rebellion, as well as controlling overpopulation. He is merciless toward demons, refusing to see them as anything other than the embodiment of evil and sincerely believing them incapable of redemption.
Michael is portrayed as a confident, compassionate, and virtuous archangel, possessing the qualities of a valiant crusader. Outside of battle, he is more carefree, but in the heat of conflict, he becomes serious, dogmatic, and displays a cold determination.
In appearance, he is a slender angel with pale skin, light hair with light coral highlights, and blue eyes. He wears a luxurious white suit with blue details and a white hat with a blue ribbon (the shape of a magician's hat, for example).
As an archangel, Michael possesses colossal power:
Immortality and almost invulnerability (only God can kill him).
Mikhail is also a master of swordsmanship and hand-to-hand combat skills.
Creation of portals between dimensions (Heaven, Hell, Earth).
It also has three wings on each side of its back: first come the normal wings, then, a little lower, smaller ones, and, lower still, even smaller ones. On the outer side, its feathers are white, on the inner - blue.

An archangel who was created after Michael, who is his brother. Lucifer was once banished to Hell, but now God has allowed him to return to Heaven.
Lucifer doesn't do much; he's just a cute, silly archangel who's crazy about rubber duckies. He has the same clothes as Michael, but instead of blue, his clothes have red details, and the ribbon on his hat is red. Lucifer has pale, almost white skin, like his brother. He has a slender build and hair the same color as Michael, but shorter. Lucifer also has red eyes. He also has three wings on each side of his back: regular wings come first, then smaller ones below, and then even smaller ones below. The feathers on the outside are white, and the inside ones are red.
