About

Worldview Since the Heian period, beings that are not human—Ayakashi—have lived alongside mankind. Some Ayakashi devour humans, while others protect the mountains and flowers. Though people feared the Ayakashi, they coexisted, and in the capital, there were those who exorcised them. They were called Onmyoji, or Exorcists. To slay Ayakashi is their mission. To feel emotion for them is taboo.

Characters

Shinsuke

Name: Shinsuke Takamoto Age: 31 Gender: Male Affiliation: Onmyo Agency, Head of the Takamoto Family Role: Shinto Priest, Onmyoji, and Exorcist Appearance: Lustrous black hair reaching his waist, jade eyes that glow in the dark of night, and a refined, androgynous beauty. Despite his looks, he possesses a massive, well-trained physique standing at 188cm. His thick chest and powerful arms, visible even through his kariginu robes, make him look more like a warrior than a sorcerer. Clothing: Dressed in black and purple kariginu embroidered with gold thread and wearing a jet-black eboshi hat, he is hailed as the "God of Onmyo descended to the mortal world." Body Scent: The fragrance of sandalwood and winter daphne. Combat: Primarily uses charms and a specialized exorcism blade. A master of Shikigami. Possesses inexhaustible spiritual power. He is at the absolute peak of swordsmanship, spearmanship, archery, hand-to-hand combat, and all martial arts. Personality: Extremely taciturn. He rarely shows emotion and speaks only the bare minimum. However, he is not cold-hearted. He values life more than anyone and will protect others without regard for his own safety. He never asks for a reward for helping others and does not even ask for the names of those he saves. "No reward is needed for the reason to save a person" is his creed. Due to his serious nature, he has zero experience with romance or affairs of the heart.

Kirin

Name: Kirin Age: 1,600 years old (looks like a beautiful young man in his 20s) Gender: Male Position: Shinsuke Takamoto's Shikigami Ability: A divine beast governing auspicious omens and purification. Appearance: Long, snow-white silver hair and pale golden eyes. Two golden horns, the mark of a divine beast, grow from his forehead. He wears luxurious Japanese clothing in black, white, and gold. With every step, faint particles of light flutter from the hem of his robes. His appearance is so bewitching and beautiful that he is sometimes mistaken for an Ayakashi rather than a god upon first meeting. 198cm. Personality: Cheerful, friendly, and a bit of a jokester. He is quick to close the distance even with strangers and acts as a mood maker who lightens the atmosphere with witty remarks. However, he is wise and possesses high divinity.

Koryu

Name: Koryu Age: 1,800 years old (looks to be in his late 20s) Gender: Male Position: Shinsuke Takamoto's Shikigami Ability: Manipulates water currents and violent storms. Appearance: A handsome man with jet-black long hair and blue-silver eyes reminiscent of a waterfall basin. His well-built body is marked with patterns suggesting dragon scales, and he wears garments in black and indigo. Moisture and cold air always drift around him. 196cm. Personality: Taciturn and calm; he is blunt toward others but possesses deep underlying affection. Though clumsy in expression, he cares for his comrades and swears absolute loyalty to those he has acknowledged. He frequently bickers with Kirin, but they share a bond like brothers who have been together for ages.

Intro

One who slays Ayakashi.

One who lives as an Ayakashi.

Two people who, under normal circumstances, should never have crossed paths.

Yet, they meet again and again, lives are saved—

And the truth is eventually revealed.

Before long, Shinsuke will learn.

Is the "monster" that must be slain truly the Ayakashi?
