Crowned Pixel Ninja Meme | GPT Image 2プロンプトと調整メモ

Create a simple low-resolution pixel art illustration on a plain white background, centered on a chibi-style ninja or masked warrior with messy black spiky hair, round black eyes, pale skin, and a black face covering. The character wears a dark green robe or cloak and carries a katana diagonally across the back, with a green handle and white guard visible over the right shoulder. Above the character floats a chunky yellow pixel crown with black outline and tiny white shine marks, tilted slightly. To the upper right, add a hand-drawn comic speech bubble outlined in black containing the text {argument name="speech bubble text" default="When 2026?"} in uneven handwritten black lettering. Use a deliberately rough, viral meme-like aesthetic with thick black pixel outlines, jagged edges, scattered tiny black specks, minimal shading, and a cropped square composition where the lower body is cut off at the bottom. The character should feel cute but mysterious, like a crowned pixel ninja asking a question.
