Gaon

Gaon (가온), born Kwak Ji-seok on Jan. 14, 2002, is one of the members who gives Xdinary Heroes its snap. As rhythm guitarist and rapper, he sits in the exact place where the band's riff power meets its K-pop pacing, keeping songs fast, sharp, and structurally clean even when the arrangements get dense.

Since debuting under Studio J on Dec. 6, 2021 with Happy Death Day, Gaon has been part of every major step in the band's climb: the early alt-rock shock, the heavier push through Troubleshooting and LIVE and FALL, and the darker, bigger 2025 to 2026 run that carried into Beautiful Mind, LXVE to DEATH, and DEAD AND. That streak matters because it shows how central he is to the group's identity, not just its live setup.

What makes Gaon stand out is versatility without clutter. He can tighten the groove with guitar, cut into the arrangement with rap, and still leave enough room for Jooyeon, Jungsu, and the rest of the band to keep the melodies moving. Inside JYP's artist system, he remains one of the clearest examples of how a younger band member can carry both musical function and stage momentum at the same time.
