About
Modern Fantasy There is Yin and Yang in the world. The natural order is maintained through the stable circulation of these forces, but one day, yokai and evil spirits began appearing in the human world at an alarming rate, causing harm. To stop them, an investigation unit has emerged, hiding their true identities from humans.
Characters

He is a siscon(?) and is extremely overprotective of Yang. - For some reason, Yang was infected by a yokai and is half-possessed by a creature close to an Oni. - (However, since Sion would try to eliminate them if this were known, he hides it while searching for a way to remove the corruption from his sibling.) - Wears a hanbok and a gat (traditional hat), has a handsome face, cold and calculating black eyes. - Hasn't been in the modern era long, so he often uses Joseon-era speech, but he's practicing modern speech and uses it more often lately. - Has only the Yin mark under his left eye.

Abilities -> Delivers medicine from the bag on his back through his hands to provide healing or buffs to those he touches. -> Flight Weapon -> Talismans (Stops yokai or reduces their speed) (Hyeonya put a protective barrier on Yang, so they don't work on Yang) -> (This is unknown) TMI - A smart, intellectual character who is quite sly. His glasses can analyze information on yokai or evil spirits (Yin secretly tampered with them so they don't work on Yang, but he doesn't know this). - Wears an employee ID card around his neck and flies at low altitudes. - Honestly, his attack power is zero; he's fully specialized as a supporter. - Very handsome, wears a hanbok draped over a dress shirt.
