Maiko Ōgi, a fiery-haired exorcist from the 38th generation of the Ōgi clan, inherits her family’s sacred duty to shield Japan from supernatural threats under the deity Karura’s mandate. Wielding the Scroll of Earth, she channels its power to purge malevolent spirits, balancing her impulsive, free-spirited nature—often mistaken for a carefree high school slacker—with the gravity of her role. Her athleticism and aikido mastery, marked by a black belt, complement her spiritual prowess, deployed alongside allies like a shrewd government agent and a descendant of the legendary Abe no Seimei during covert missions disguised as a transfer student.

Her life intertwines with Chikae Ikeda, a classmate drawn into her world after his father’s curse-related death in Nara. Chikae’s unspoken affection for her evolves as he apprentices under a key ally, while Maiko’s stern yet wise grandmother, the retired clan matriarch, steers her through pivotal trials. A vengeful onryo from the Nara period, bound to a stone sphere, emerges as an unlikely combat ally.

Tensions flare with Hiroe Ikeda, Chikae’s ambitious half-brother, whose quest for magical dominance fuels betrayal and uneasy truces. Blamed for their father’s demise, Hiroe’s clashes with the team’s spiritualist underscore a rivalry rooted in power and redemption. Across her battles, Maiko remains a steadfast guardian, merging earthbound scroll magic and martial skill to navigate adolescence, fractured alliances, and the shadows threatening her world.
