Use a glossy Japanese VTuber debut-thumbnail look: oversized rounded-gothic kanji with thick white fill, lavender-to-violet gradient shadow, dark purple stroke, tiny star cutouts, and sparkling bevel highlights. Pair it with delicate cursive English in a thin handwritten script and small serif subtext for an ojousama/elegant-school feel. Character styling should resemble modern Live2D key art: clean cel shading, glossy violet irises with star-shaped catchlights, soft blush, flowing layered hair with translucent rim light, and frilled fabric rendered with pearly whites and pale lavender shadows. The logo area should feel like an idol nameplate: bubbly Japanese lettering, ribbon tails, small butterfly/star motifs, metallic gold accents, and a compact romanized subtitle beneath. Use a real streaming-mic silhouette: black cylindrical condenser mic in a shock mount, circular pop filter in front, side yoke/boom arm hints, and a satin purple bow tied around the stand. Keep mobile-thumbnail readability with high contrast, bold outlines, separated text blocks, and a close expressive face. Sources: Streamlabs, VtuberLab, RODE/B&H, YouTube thumbnail guides.
