Create a flashy Japanese YouTube thumbnail in a high-impact anime promotional style with explosive lighting, dense spark effects, and dramatic contrast. The composition is a single unified scene with a dark black-and-neon-green background, gold glitter bursts, and a subtle city skyline silhouette along the bottom edge. On the right side, show a cute chibi anime boy from the waist up with messy dark brown to black hair accented by vivid neon green streaks and a small red accent near one side, huge bright green eyes, an open excited smile, and an energetic pose pointing directly toward the viewer with one hand while the other fist is raised. He wears a black hoodie layered under a green jacket with glossy highlights. On the left side, place 1 glowing green hourglass with swirling green energy inside. Fill the image with intense starbursts, lens flares, golden particles, and speed-line energy for a viral thumbnail look. Add 5 bold Japanese text elements in oversized display
Typography: a red ribbon banner across the upper left reading {argument name="top banner text" default="4月28日スタート"} in thick yellow letters with white edging; the main central headline in massive metallic gold kanji reading {argument name="main headline" default="ついに解禁"} with heavy black shadow and bright gold texture; a large white-and-green subheadline across the lower left reading {argument name="subheadline" default="AI副業で人生変わる"}; 1 green rounded badge near the lower center-right reading {argument name="bonus badge text" default="無料10大特典"} in bold white and yellow text; and 1 black slanted banner in the lower right reading {argument name="corner banner text" default="近日公開"} with smaller white English text beneath it saying COMING SOON. Make everything feel urgent, celebratory, and attention-grabbing, like a high-CTR launch announcement thumbnail, with thick outlines, glowing edges, metallic text, and layered depth.
