For X:IN’s 3rd mini album Defend Myself, we developed a visual concept expressing duality and inner conflict. Apocalyptic mood, mirror symmetry, synchronization, reversal, and black-and-white contrast were key themes. The brain metaphor visualizes psychological tension and self-defense, while vintage textures and sand-like fading typography express gradual erosion. We also redesigned the X:IN logo to align with the new concept and strengthen the group’s identity.
