Affiche de monstre manga sombre

A dark monochrome manga-style horror illustration on a pure black background, in a tall vertical poster composition. Centered at the bottom is a small lonely teenage boy with messy short dark hair, sitting on the ground with his knees pulled to his chest and his arms wrapped around them, head slightly bowed, conveying fear, isolation, and helplessness. Towering over him is a gigantic biomechanical demon or armored monster head descending from above, with a long angular skull-like face, sharp chin, narrow hollow eye sockets, layered helmet-like plates, and a jagged open mouth. Surrounding the boy are exactly 2 enormous skeletal clawed hands, one on the left and one on the right, framing him like a cage; each hand has long segmented metallic fingers ending in sharp pointed tips, bent inward menacingly. Render everything in rough scratchy white ink linework and heavy crosshatching against deep black, with intense high-contrast seinen manga energy. Add vivid neon purple paint-like liquid in splashes and long dripping streaks from the monster’s face, the hands, and the ground, pooling around the boy for the only strong color accent. On the upper right side, add vertical Japanese text reading 逃げちゃダメだ, and beneath it in small white English text: EGO BORDER: ACTIVE. The mood is oppressive, psychological, claustrophobic, and nightmarish, like a dark anime poster about inner fear and mental collapse.
