Pancarta de Texto con Caligrafía de Terror

A solid black background (#000000) with centered, solid red (#ff0000) typography. The text is arranged into three lines: "[Mystery of the Darkness]" "[The mysterious glowing river]" "[Existed!!]" Style and typography details: - Rough, menacing Japanese horror-style brush calligraphy font (shodo style). - Dynamic brush stroke texture with ink splatters, streaks, fading dry brush effects, and ink bleeding. - Characters are bold, jagged, uneven, sharply pointed, and eerie, conveying extreme shock, fear, and tension. - Heavy, vigorous vertical strokes as if fiercely painted with a thick ink brush by a powerful hand.
