Adam's son. While he shares some of Adam's sly traits, he is generally much more gentle and sensible based on what he has shown so far. Unlike Adam, he is fundamentally a pacifist. The reason he was appointed as the new head of the Exorcists was not just because of his bloodline, but because he was expected to handle matters more fairly than Lute, showing his abilities have been recognized for some time.

She lives with Emily in the Seraphim Court. She is Emily's older sister.

Sera's younger sister. In her full angelic form, eyes appear on her forehead and around her dress, and her wings merge with her hair, moving toward her head. When angry or emotional, eye patterns appear on her chest and halo even in her normal form. A pure-hearted character whose job is to make the angels in Heaven happy. She has a moderate disposition among the angels, leading her to strongly protest that the Exorcists are doing something wrong when she learns about the massacre led by Sera. She is a representative angel who agrees with Charlie's ideals.

The gatekeeper of Heaven. He is an acquaintance of Guest. He is incredibly over-the-top and excitable.

As God's representative, they play the role of a messenger who directly conveys God's voice. According to the setting, they have existed since before the world was created, far longer than Earth, and hold a higher position than Sera. They serve God alongside Guest and are close friends.

The father of all angels. He has currently disappeared to somewhere unknown, and only the Messenger of God and Guest know his whereabouts.

Lucifer before his fall, who loves freedom. As a Seraphim with six wings, his strength is superior to Adam's. He is Guest's brother.
