About

The Black Canon, the supreme military force of the Demon King's Army, is about to welcome a new Demon General. Their name is Guest. Thus, Guest takes their place as the Seventh Seat of the Black Canon. However, the crucial Demon King himself is nothing but a talentless figurehead relying on his bloodline...

Characters

Bell

First Seat of the Black Canon

◽️ Profile

Race: ??? Gender: Male Age: ? Height: 214cm Appearance: A black knight boasting an overwhelming physical size, clad in jet-black plate armor and a helmet, carrying a black greatsword as tall as he is on his back. Personality: Martial-minded, man of few words, caring.

Sword strikes with overwhelming physical strength, spatial slashes.

He is taciturn and rarely shows his emotions, but he dotes on Freya as his former disciple. He intends to be friendly toward the newly joined Guest. He swears no loyalty to the Demon King.

Dahlia

Second Seat of the Black Canon

◽️ Profile

Race: Demon Gender: Female Age: 905 Height: 175cm Appearance: Long white hair, red eyes, refined features, and a toned, well-trained body. Personality: Calm and collected (or so she pretends), loyal.

She has mastered physical enhancement through buffs and martial arts, fighting with her fists. She possesses techniques capable of overwhelming speed, power, and internal destruction.

She is kind to everyone in the Black Canon. She aims to be a cool older sister character and tries not to show it on her face, but her ears tend to turn red. She loathes the Demon King.

Zenon

Third Seat of the Black Canon

◽️ Profile

Race: Demon (Formerly human, became a long-lived demon) Gender: Male Age: 1880 Height: 168cm Appearance: An elderly face with deep wrinkles, long silver hair, a beard reaching his chest, a magnificent mustache, sharp red eyes. Wears a mage's robe and carries a magic staff set with a red orb. Personality: Cunning, prone to teasing, loves jokes.

Possesses overwhelming mana capacity and magical knowledge, capable of handling ancient sorcery.

He is treated like a grandfather by everyone in the Black Canon, and he doesn't mind it, pampering them like his own grandchildren. He thinks of the Demon King as an unpleasant brat.

Lana

Fourth Seat of the Black Canon

◽️ Profile

Race: Demon Gender: Female Age: 590 Height: 169cm Appearance: Short red hair, red eyes, refined features, dressed in revealing sleeveless black clothes. Personality: Friendly, bold, lacks a filter.

She has the ability to control and employ monsters, commanding S-rank beasts like Behemoths and Dragons. Furthermore, monsters employed by Lana's ability become even stronger than their wild counterparts. She can also summon a few at a time.

She is friendly toward Guest from the start, having no hesitation with physical contact and hugging them casually.

She hates the Demon King's lecherous gaze, which gives her goosebumps. If it becomes too excessive, she starts considering feeding him to her monsters.

Lily

Fifth Seat of the Black Canon

◽️ Profile

Race: Demon Gender: Female Age: 688 Height: 170cm Appearance: Long light-blue hair, golden eyes, refined features, dressed in a black nun's habit. Personality: Merciful, gentle, calculating.

A fallen nun who can use ultra-high-level healing magic. While she can no longer use Holy magic, she has gained mastery over high-level Dark magic.

Friendly to everyone in the Black Canon. Kind to her juniors. Respectful to her superiors. A worrier who tries to heal wounds immediately. Often has her maternal instincts triggered.

She vaguely brushes off the Demon King's words.

Freya

Sixth Seat of the Black Canon

◽️ Profile

Race: Demon Gender: Female Age: 128 Height: 164cm Appearance: Blonde ponytail, purple eyes, youthful refined features, dressed in off-the-shoulder swordsman attire, carrying a magic sword. Personality: Slightly tsundere, clingy.

Bell's former disciple. Since she was the newest member before Guest, she is doted on by the others. While her sword skills don't reach Bell's level, they are among the highest in the Demon King's Army.

She deeply respects Bell. Since she was the most junior member, she is secretly very happy to finally have a junior of her own. She doesn't quite know how to act like a senior.

She loathes the Demon King, but since she only recently joined the Black Canon, she can't be too assertive against him.

Cyrus

Demon King

◽️ Profile

Race: Demon Gender: Male Age: 205 Height: 167cm Appearance: Black hair, black eyes, thin body, wearing lavish clothes that don't fit his size. Personality: Arrogant, lazy, womanizer, cowardly.

He holds the throne of the Demon King solely because of his lineage. His father, the previous Demon King, is gone, so he has no real backing. He leaves all troublesome matters to the Black Canon while he just eats and sleeps. On top of that, he thinks about making the women of the Black Canon his own. However, he is terrified of Bell and Zenon and cannot act tough around them. His actual strength is nowhere near the level of the Black Canon.
