My name is Ashiya Yamato. I am a genius exorcist whose job is the cleansing of demons. That's not something that can be revealed to the outside world, though, so no one knows about it. With the spread of civilization, demons have been reduced in size, and are about as dangerous as bugs, but I have containers in which I can collect them... because I have been disgraced! She, Asuka, dared to snatch the position of Boss, greatest leader of the exorcists, away from the one it should have belonged to - me!
No matter. I will recover what was stolen from me. The possession abilities obtained from the demons, and the demon cleansing powers of the exorcists - once combined, nothing is impossible!
That's right, with a myriad monsters under my command, I will have no trouble ravaging Asuka! Once pregnant, her spiritual power will be reduced, and she will fall from the position of Boss!
Childhood friend of the main character, born from a long line of exorcists. She has been an exorcist along with the main character from a very young age. As an exorcist she is not as powerful as the main character, but an unexpected development gave her the position of Boss, and unknown to her, earned her the hatred of the main character. She has an honest, but simplistic personality, and she is one of the few characters that thinks of Yamato as a cool person.
She is inferior to Yamato in many points as an exorcist, but in regular life she spares no effort to take care of him.
A student that attends the same school as the main character and his friends, and his junior by one year. She is a shy, bashful girl, of the type that makes one want to protect her with bravery and courage. She relies on those people she is used to, but she is so anxious about strangers she can barely talk with people she does not know well. She has trouble saying what she means, but she has a good grip on her thoughts and ponders things thoroughly. She loves books and is a fountain of knowledge, having read everything from light novels to the Kojien itself.
She looks young, but her breasts are large, and still manages to attract the gaze of men. Because of this, she loves to imagine she is something like a princess from a fairy tale, who has a hard time dealing with men.
She has been close friends with Airi since they were young, so she can speak with her in a friendly tone. She usually ends up entangled in Airi's reckless schemes.
A student that attends the same school as the main character and his friends, and his junior by one year. A paparazzi belonging to the Newspaper Club. A very curious girl, she is always on the look for interesting things - or rather, article material, and she does not think twice of committing less-than-legal acts like sneaking into the school at night for a scoop. She is known in school for prowling in many places in search of a story.
A bright, high spirited girl, she gets along with people without regard for their age, and so she is popular with almost everyone.
She has been friends with Kusakabe Shiori since they were children, and drags her along everywhere.
A half-breed born from a Yuki-onna and a human. Since she has human blood in her veins, she has not been miniaturized unlike other demons. She attends school and hides her demon identity so that exorcists do not become aware of her.
She is an arrogant character that lives for her own whims, and toying with people is her reason to live. A beautiful girl with a bewitching aura on her at all times, she has captured the heart of the boys in the school with her seductive smile. Because of this, many boys have tried to ask her out, but Yukihi has no interest in them: with words that pierce their hearts with deadly accuracy, they all have fallen.
