นักปราชญ์จิบิกับมาสคอตต้นอ่อน

A cute chibi anime-style single-panel illustration on a warm off-white, lightly textured paper background. Subjects: Exactly two characters. On the left stands [a brooding black-haired boy] with messy layered black hair, gray eyes, round wire-frame glasses, pale skin, and a slightly annoyed neutral expression. On the right, a simple round white mascot creature with tiny black oval eyes, rosy cheeks, an open smiling mouth, and a small two-leaf green sprout on its head. The mascot playfully reaches up with both arms to tug at the boy's closed collar, while the boy stands stiffly and resists. Attire & Props: The boy wears an elegant all-black layered outfit including a high-buttoned collared shirt (visibly closed), patterned vest, short dark jacket, black trousers, black shoes, and delicate gold chain accessories. In his left hand, he holds an oversized vintage black hardbound book with worn corners, gold filigree trim, a central emblem, and a cream label reading "[人間取扱説明書・暫定版]". Text & Composition: Exactly one speech bubble above the mascot containing the text "[閉めな]". Soft watercolor and ink line art, subtle beige ground shadow beneath both figures, and generous negative background space. Exaggerated chibi proportions with large heads and small bodies. No extra characters or objects.
