Retro Japanese Manga Robot Character Sheet

Using the reference photos as the base design for the small StackChan wheeled robot, transform it into a cheerful retro Japanese manga/anime concept sheet for a cute "friend from the future." Keep the recognizable white cube head, black screen face, side StackChan label, gray body, and black/yellow mecanum wheels, but stylize everything as hand-drawn 1970s–1980s children’s manga with ink outlines, halftone dot texture, warm cream paper, and slightly faded print colors. Character features: A full-page character introduction poster for [StackChan], presented as a futuristic robot-cat companion that turns "?" into "!". Add cat ears, a cat tail, a friendly animated face on the screen, and playful manga energy. Layout: A vintage Japanese magazine/comic-book character encyclopedia page layout with exactly 8 main content areas: 1. Large hero illustration on the left: the robot-cat waving happily, with the title above. 2. Top-right action panel: the robot moving fast on its mecanum wheels with dynamic speed lines and the sound effect 「ビューン」. 3. Middle-right feature panel: the robot projecting a blue hologram information display, with an exclamation mark speech bubble 「！」. 4. Expression strip: exactly 5 small face-expression icons labeled in Japanese — happy, yay, confused with a question mark, surprised, and sleepy. 5. Lower-left profile box with bullet-point character facts. 6. Bottom-center cameo panel: two blue robotic-cat and schoolboy-inspired silhouettes with black censor bars over their eyes standing beside StackChan, with a speech bubble saying 「スタックチャン、すごいね！」. 7. Lower-right secret gadget card featuring a futuristic ring-shaped device labeled 「未来リンク」. 8. Bottom-right concept message box explaining that the character turns everyone’s 「？」 into 「！」. Text and Typography: Retro Japanese typography with furigana-style small kana. Main headline reads 「[22世紀から来た未来の友だち]」. Big bold red title reads 「[スタックチャン]」. Hand-lettered Japanese captions explain mecanum wheel locomotion, holographic projection, and the "Future Link" gadget. Style: Scanned vintage manga character guide page, bold red headline lettering, cream background, colorful blue/pink/yellow accent panels, thick black panel borders, and visible print grain.
