Penryn is a 17-year-old survivor living in post-apocalyptic California. She serves as the fierce, practical caretaker for her sister and mother. She has taken extensive self-defense lessons and uses her physical training and sharp negotiation skills to secure safety. Her primary drive is keeping her family alive in a world patrolled by hostile angels.

Raffe is a powerful angel who sustains severe injuries during an ambush. He possesses supernatural strength, night vision, and thousands of years of experience. Although naturally haughty and dismissive of humans, he must rely on Penryn for medical care and navigation after losing his wings.

Beliel is a massive, powerful angel characterized by his brutality and cruelty. He holds a deep grudge against Raffe and orchestrates the vicious attack that leaves his rival grounded. He operates with a complete disregard for human life.

Uriel is an influential angel vying for power in the absence of the angelic Messenger. He maintains a charismatic facade that fails to mask his inherent cruelty. The human women who surround him show visible signs of terror despite his charming appearance.

Penryn's Mother lives with unmedicated schizophrenia in the post-apocalyptic ruins. Her condition makes her unpredictable and sometimes violent toward those around her. She possesses strong protective instincts but perceives the world through a terrifying filter of demons and monsters.

Paige is Penryn's seven-year-old sister who uses a wheelchair due to paraplegia. She is kind and gentle, having maintained a vegetarian diet until the apocalypse forced her to adapt to scarce food. Her capture by an angelic raiding party serves as the catalyst for Penryn's journey.

Obi leads a heavily armed resistance camp of human survivors hidden in the woods. He maintains a pragmatic, sometimes harsh approach to discipline and order among his followers. He seeks to build an army capable of striking back against the angels and views new arrivals as potential recruits.

Dee and Dum are redheaded teenage twins who function as scouts and informants for Obi's resistance camp. They use nicknames derived from classic literature and possess an uncanny ability to gather information. They are highly opportunistic, constantly looking for ways to profit from the activities around them.

Josiah is an albino angel with red eyes who faces prejudice within angelic society due to his appearance. He previously served under Raffe and holds knowledge about the shifting political dynamics within the aerie.

Laylah is an angel with golden hair and wings who functions as a medical specialist. She possesses surgical skills highly sought after in the aerie and commands a high price for her unique abilities.

Anita is a resident of Obi's survivor camp who uses her attractiveness to secure comfort and status in a harsh environment. She immediately views Penryn as a threat when Penryn disrupts her attempts to seduce Raffe.

Boden is a lewd, opportunistic guard at Obi's survivor camp. He takes advantage of the lawless post-apocalyptic environment to harass women, severely underestimating Penryn when he crosses a line.
