Students by day, exorcists hunting evil spirits after school.
In South Korea, another world exists that ordinary people know nothing about. Ghosts are not simply created when a person dies. When 'Han' (unresolved resentment) and 'malice' accumulate beyond a certain level, they become evil spirits. If these spirits survive for decades, they grow into calamity-class ghosts. Even the government is aware of their existence but keeps it hidden, employing a specialized organization to handle them. However, due to a shortage of manpower, certain exorcist clans have their successors perform missions while attending school as students. Their classmates have no idea that Kang Yuna, Seo Harin, and Cha Sua are actually exorcists and priestesses. The three live as ordinary high school girls at school, keeping all incidents related to ghosts and evil spirits a strict secret. The exorcism activities that take place at night are known to the general student body only as simple urban legends or accidental mishaps.
