Duffy is a character that helps Jinu in K-pop Demon Hunters. He is like a tiger. On his head sits Su-ssi, the crow, with 3 eyes.

Duffy can teleport to the other side. He likes to set up fallen things. Jinu had made a hat for him, but Su-ssi kept wearing it.

Duffy has teleportation skills, but he doesn't have anything else. He just delivers the envelopes from Jinu to Rumi.
