Jinu: The leader of the Saja Boys and the film's primary male character.
He was a human from over 400 years ago who made a deal with Gwi-Ma for a beautiful singing voice to lift his family out of poverty, a bargain that ultimately condemned him to the demon world.
His character serves as a foil to Rumi, grappling with his lingering humanity and profound guilt over his past actions.
Jinu is voiced by Ahn Hyo-seop, with his vocals provided by Andrew Choi.
The character design was heavily influenced by Korean actor and singer Cha Eun-woo.
