Despite her mercenary attitude, she remains highly skilled in dispelling spirits. ; : : Tadao Yokoshima is a 17-year-old high school student and underpaid assistant at Mikami GS, earning only 250 yen per hour (later raised to 255 yen).

Karasu's Church ; / Father Karasu : : Father Karasu is a 45-year-old Catholic
priest and exorcist who trained both Reiko and her mother. Expelled from the Church for unorthodox methods, he remains one of the most skilled exorcists due to his Myoushinzan training.

Doctor Chaos' Lab ; : : A centuries-old
alchemist and exorcist of genius intellect, his advanced age and immortality have granted extensive knowledge of the supernatural. However, his memory operates like a finite storage system—acquiring new information forces him to forget something previously known, requiring constant review of his old texts. Among ghost sweepers, he faces particularly severe financial difficulties, frequently evading his landlady over unpaid rent. This poverty led him to use Maria as collateral for a loan to construct Teresa. His economic struggles extend even to fictional depictions, appearing as a peasant in one media portrayal. ; : : Maria is a combat-ready
gynoid created by Dr. Chaos in the likeness of his former lover. Designed for strength, speed, and durability, she conceals various weapons within her body.

Twelve Heavenly Generals, each taking animal forms inspired by

Despite her youthful appearance and demeanor, Rokudō is chronologically older than Mikami, with her mother's pregnancy predating Mikami's parents' meeting. ; : : The current head of the Rokudō estate previously served as master of the Twelve , retaining full control over them.

Trained briefly by Father Karasu at age 18, she operates with a resolute commitment to justice, motivating her career choice.
Other Yokoshima's family members ; : Daishū Yokoshima, Tadao Yokoshima's father, shares his son's womanizing tendencies but demonstrates greater success in romantic pursuits.

Gods ; : : A member of the dragon god race, she operates a spiritual martial arts dojo atop the sacred mountain Myoushinzan.

He is the one who created Luciola, Vespa and Papilio. ; : Luciola, the eldest of Ashtaroth's three enhanced servants, originates from a
