A fearsome t-rex stands over a mystical Dead Note, its scales glistening in a dim, eerie light. The notebook, ancient and dark, lies beneath the t-rex massive claws, emitting a faint supernatural glow that illuminates the creature's intense, menacing gaze. Shadows swirl around the t-rex as it seems drawn to the notebook's sinister power, with lightning illuminating the scene in sharp, haunting flashes of blue and purple. The t-rex eyes gleam with a mysterious hunger, as if sensing the forbidden knowledge contained within the Dead Note. The atmosphere is dark, foreboding, and filled with suspense, blending prehistoric might with supernatural horror.
