T-Shirt Tシャツ

A cheerful pink book character stands proudly with hands on its hips, dressed like a tiny superhero with a flowing red cape, matching boots, and gloves. Its simple smiling face and rounded shape give off a cute, confident charm, while bold outlines and smooth gradients add a polished cartoon feel. Colorful sketch strokes near the edge add a playful, creative accent against the deep black background, making the character feel lively and imaginative.
