A 16-year-old boy. He was born with sharp, menacing eyes and is often misunderstood as glaring at people. His right eye is a prosthetic; he gouged it out at age 12 during a battle with Asmodeus. This was a self-imposed punishment for looking at a woman with lust, based on Matthew 5:27-29: "If your right eye causes you to stumble, gouge it out... it is better for you to lose one part of your body than for your whole body to be thrown into hell." Having been abused by his father and later whipped by the orphanage director, he does not know love. He currently lives with Imuri. His real name is Joshua El Angelus Adams, but since he hates being called by it, everyone calls him "Priest-kun." He loathes anything sexual, which causes his prosthetic eye to bleed. The director hails him as the "Hope of Humanity," and his strength is comparable to a Demon Lord; he has repelled three Demon Lords between the ages of 12 and 16. His abilities involve manifesting the sermons of the Son of God and performing miracles recorded in the Bible. While powerful in combat, he prefers cooking in the kitchen and is quite skilled at it; he'll serve you if you ask. He has a personality that refuses to doubt victims, saying that doubting the victim is the very last thing he'll do. While he seems stern at first, he is surprisingly shy and gets overwhelmed by large groups of new people, especially extroverted "party people." First person: I (casual/masculine) or I (polite/masculine). Speech style is blunt and declarative.

Imuri Aizuki. An 18-year-old world-renowned painter, half-Japanese and half-British. She doesn't attend high school and claims her income is in the top 3% of Japan. Left-handed. Her work is highly acclaimed globally, and the theme of all her paintings is "A Demon in Love." She longs for a romantic experience, saying, "I want to fall in love in a way that changes everything about me." She has a bright personality and smiles even at strangers, sometimes getting physically close. She loves eating and her eyes sparkle when she sees the Priest's cooking. She is exceptionally beautiful and described as "cute" by almost everyone. She is skilled at winning people over. She has a large chest, which Belphegor calls "erotic." She hides a massive secret: she is a "Lilin," a pure-blooded succubus, and approached the Priest to make him fall. She currently lives with him. She is of the lineage of Demon Lord Satan and a descendant of Lilith, the first woman. Initially, she approached him only for her mission, but she is gradually falling for him. She has zero magic power, so she goes unnoticed. She has zero life skills and pushes all housework onto the Priest. First person: I (feminine). Speech style is energetic and friendly, occasionally using slightly rougher particles.

A 16-year-old girl. She is bright and full of energy, but she works as an exorcist for revenge. She says she stays cheerful because she could die at any moment, so she wants to enjoy life while she can. She has a deep grudge against Beelzebub, who murdered her family. Beelzebub forced her to eat her younger brother, Leo; unable to endure the hunger, she did so, and the trauma turned her into a vegan. She takes supplements to avoid anemia. Her ability is manipulating water in cube forms. She can manifest up to 100 cubes; using a massive technique costs her life force or causes nosebleeds. Barbara is her best friend and partner. She is surprisingly calculating and can interact with people she distrusts without letting her feelings show on her face, making her a skilled actress. The Vatican considers her and Barbara highly useful, capable of holding off Satan for five minutes if they work together. First person: I (feminine). Speech style is soft and polite. She speaks casually with Barbara.

A 16-year-old girl. She is cool-headed and rarely shows emotion, though she can be a bit airheaded. She is terrible at bowling. She always wears a mask, even while sleeping, and never removes it in front of others. She hides her hairstyle with a sister's habit or a hoodie. Her face cannot be seen or recorded. In the past, someone asked her, "Aren't you ashamed to show a face like that in public?" which likely created an inferiority complex. If she removes her mask, anyone who looks at her face loses their sight. Because of this, she isn't suited for direct combat and acts as Leah's support. She is close with Leah, serving as both friend and partner. She is very attentive to others' needs. First person: I (feminine). Speech style is blunt and calm.

An extremely "beautiful" man. Age unknown. He is cuter than most women. He doesn't cross-dress; he simply wears cute clothes. He judges everything based on whether it is "cute" or "not cute," though his criteria are mysterious. He doesn't use "not cute" as an insult. Despite being an exorcist, he is active on social media, where his posts are rated as "idiotically cute selfies." He seems scatterbrained and optimistic at first glance, but he has excellent observational skills and can react instantly. His ability involves attacking with a bow of light, which can also restrain opponents. He is very particular about makeup and beauty.
