Retro Japanese Lovart Event Poster

A bold Japanese event thumbnail poster with a light gray background and a retro arcade pop art style. At the center of the composition is a large diagonal lettering "LOVART" in oversized white block font with a thick black border, a substantial 3D feel, subtle pixelated stepped inner edges, and yellow halftone shadows. Above the lettering is a large, bright yellow Japanese title with a black border: "AI Design Application Training Association". Below the main lettering are two lines of slightly slanted, bold white Japanese subtitles with black borders: the first line reads "Latest Tool Gun ×", and the second line reads "Pro's Dark Continuation Power". At the bottom center is a pixelated black text label with a yellow shadow that reads "speaker kats". On the right side, overlapping with the main logo, a bright yellow, jagged star-shaped badge with a thick black border is added, containing three lines of stacked black text: "5.10 (sat)", "19:00", and "START". Around the logo are 12 playful, game-style decorative icons and shapes: two yellow pentagrams, two pairs of red cherries with green stems, two small yellow game controllers, a black circle with a yellow controller symbol inside, two solid yellow triangles, a yellow dashed triangle, a white-outlined polygon, and a small black-and-white spiral square. A high-contrast color scheme of yellow, black, white, and light gray is used, combined with thick outlines, sticker-like layering, cartoonish halftone dots, and clear, legible Japanese typography.
