An avatar of the cartoon character "Koyomi Araragi" from the Monogatari Series, wearing a red vest and blue cap on their head with a smiling expression. The background is pink. The style is reminiscent of Japanese anime or the work of Studio Ghibli in the style of Miyazaki. Capture the character's detailed features, such as big eyes and a small mouth, to convey a cute appearance. Use vibrant colors to emphasize their cheerful demeanor while maintaining a realistic yet whimsical aesthetic in your illustration. --niji 6
