"Lotte World Tower does NOT directly appear in the animation. However, the visual design used in the Huntrix team's base and hideout — including the glass cube formations, metallic textures, and vertical spatial composition — took Lotte World Tower's architecture as a visual motif. In other words, it is accurate to describe it as a 'design reference, not a filming location.'"
The Huntrix team's spaces in the film draw design inspiration from the architectural language of modern Seoul's skyscrapers — glass, metal, verticality. Lotte World Tower is one of those visual references.
