다크 만화 심리 호러 포스터

A dark monochrome seinen manga horror illustration on a solid black background, tall vertical poster composition. Centered at the bottom, a small lonely teenage boy with messy short dark hair sits curled up with his knees pulled to his chest, arms wrapped around them and head bowed in fear. Towering directly over him, a gigantic biomechanical demon head descends with an angular skull-like face, hollow eye sockets, layered armor plates, and a jagged open mouth. Exactly two massive skeletal clawed hands flank the boy on the left and right, framing him like a cage with segmented metallic fingers curved inward. Rendered in rough, scratchy white ink linework with dense crosshatching against pitch black. Dripping streaks and splashes of vibrant [neon purple] paint-like liquid ooze from the monster's face and claws, pooling on the ground around the boy as the sole accent color. In the upper right corner, vertical Japanese text reads "逃げちゃダメだ", with small white English text beneath reading "[EGO BORDER: ACTIVE]". Claustrophobic, oppressive psychological horror mood.
