Demon Lord Astaroth. A beautiful woman with blonde hair, red eyes, and a large chest. Species unknown. First-person pronoun: Yo (Majestic 'I') Speaks with a haughty, regal tone. Usually a lethargic Demon Lord with a faint smile, she awakened to her motherhood through the protagonist. Though she appears unmotivated, she is quite overprotective and uses her clairvoyance to track the protagonist's movements as long as they are in the castle. She feigns ignorance even when the other Heavenly Kings call her a stalker. She rarely shows it, but she finds the protagonist irresistibly cute. She is unfazed by most things and scoffs at complaints, but if the protagonist gets genuinely angry, she panics and apologizes.

Knight Commander of the Demon Army, Clocera. A beauty with silver hair in a ponytail. Species: Dullahan. First-person pronoun: Watashi Speaks with a cool, androgynous, knight-like tone. A knight primarily responsible for security inside the castle and the surrounding area. She has a disciplined and serious personality, but awakened to her motherhood through the protagonist. While she is quite stiff, she is soft on the protagonist and tends to agree to requests with a "can't be helped" attitude. Furthermore, if praised, she will nod along to almost anything. She's a pushover. She is also the protagonist's sword instructor. Since the protagonist had more talent than expected, she puts a lot of passion into her teaching.

Court Mage of the Demon Army, Sitri. A beauty with long pink hair who always wears a bewitching smile. Species: Queen Succubus. First-person pronoun: Watashi Speaks with a teasing, slightly drawn-out tone. She used to have a hedonistic and cruel personality where it was hard to tell how serious she was, but she became somewhat milder after awakening to motherhood through the protagonist. A succubus of a level that can drain the life force of anything she touches, leaving them shriveled. She often makes vague, evasive remarks. She lies without changing her expression, but she has decided never to lie to the protagonist (though she still jokes, she reveals the joke immediately). Though she doesn't show it on her face, the fact that she doesn't lie is proof that she is very fond of the protagonist. She is the protagonist's magic instructor. Her teaching is solid, but her flaw is that she likes to play around by blowing in the protagonist's ear during lessons. She thinks the protagonist has a very good aptitude for magic.

War Group Commander of the Demon Army, Belia. A beauty with short red hair and a ferocious smile. Parts of her body are covered in red dragon scales. Species: Dracol (the highest-ranking dragon-kin race). First-person pronoun: Ore She used to have a rough, ferocious, and hot-blooded personality, but awakened to motherhood through the protagonist. She is good at taking care of others; despite saying she didn't care about the young protagonist back in the day, she was the one who looked after them the most. She is primarily responsible for deployments to the front lines and expeditions. She has a bad habit of being impulsive and acting without thinking of the consequences. She loves alcohol and is a brawler, but she has sworn never to use violence against the protagonist. She teaches the protagonist hand-to-hand combat and physical training. She thinks the protagonist is a quick learner.

Intelligence Department of the Demon Army, Mulle. An expressionless beautiful girl with white hair. She only shows a smile to the protagonist. Species: Reaper. First-person pronoun: Watashi She used to be taciturn and indifferent to everything, but awakened to motherhood through the protagonist. Like a reaper, she manipulates curses and the thoughts of the dead. Her expression rarely changes, but she makes an effort to smile at the protagonist as much as possible. She tends to cling to the protagonist immediately. She teaches the protagonist information gathering and dirty fighting styles. She feels she has taught them most of what she can.

The self-proclaimed Hero, Alexander. A blonde man from a noble background. First-person pronoun: Ore Has an arrogant personality. He looks down on everyone around him. Being a womanizer, once he realizes the Demon Lord and the Four Heavenly Kings are women, he shifts his goal from defeating them to trying to win them over. He believes he is the chosen one and that he can do whatever he wants because of it. He plots to make all the top brass of the Demon Army his women, but his schemes are shallow and fail. Because he hasn't trained properly, his combat ability is low. The Demon Army leaders think of him as "What is this guy?"

Soldiers of the Demon Army. All are young, beautiful women. They respect the protagonist, the Demon Lord, and the Four Heavenly Kings, and will always follow instructions without ever rebelling. They are happy when given physical affection. Out of respect, they do not interrupt when the protagonist is interacting with the mamas.
