Pastel Anime Promo Poster

Create a bright and soft-toned anime promotional poster for a fictional slice-of-life comedy series. The composition should be a single-page Japanese anime key visual, featuring a female protagonist at the center, surrounded by five illustrated moments and blocks of Japanese promotional text, presenting the style of an anime promotional poster. The protagonist is {argument name="character name" default="Mochiko-san"} A cute anime girl with short, white hair that fades to silver at the ends, bright blue eyes, soft blush, and low twin ponytails tied near her shoulders. She wears an oversized black hood shaped like a lop-eared dog, round silver goggles, a black choker with metal embellishments, and a futuristic black and white off-the-shoulder crop top adorned with a small badge on the chest, paired with separate black arm sleeves, super-short white shorts with black trim, a single leg strap, and a small side bag at her waist. Her body proportions are youthful and anime-style, slender and petite, with a slightly exaggerated bust, presenting a delicate modern moe character design. She stands in the center of the frame, a gentle smile on her face, holding a pen in one hand as if preparing to make a mistake while writing, facing the viewer with a confident and sweet demeanor. Five supporting illustrations of the same character are placed around her: 1) Top left, a chibi-style scene where she is outdoors, arms outstretched, mouth agape, dramatically crying; 2) Bottom left, a comedic scene where she is face down on a table or floor, exhausted and flustered, surrounded by scattered papers; 3) Top right, a half-body portrait where she holds up a sign with Japanese writing on it, looking apologetic; 4) Bottom right, a cheerful half-body portrait with eyes closed and a raised fist in encouragement; 5) A small background portrait behind the text in the top right corner, used as a character label. Two small white mascot creatures, round like mochi, with dotted eyes and small mouths, one large and one small, float or stand beside the heroine near the bottom center. Soft spring colors, including pink, sky blue, mint green, peach, cream, and white, are used, with cherry blossom petals and rounded graphic shapes scattered in the background. The background should create a light and celebratory atmosphere with subtle outdoor landscape blurs and decorative curves, stars, and bubbles. The poster is filled with playful, commercial anime-style Japanese typography: a large, multi-colored headline in the top left corner with subheadings above, a red seasonal broadcast announcement, a pink "Arasuji" (synopsis) box on the left containing multiple lines of text, a blue explanatory box in the bottom left corner, vertical and slanted exclamation marks surrounding the characters, and a pink staff credits block in the bottom right corner. A prominent character name banner is added in the top right corner. All text should look like authentic print Japanese promotional copy, with the headline in a rounded, colorful font and smaller text in a clean, magazine-style font. Overall atmosphere: cute, comedic, slightly chaotic, professionally designed anime key visual, suitable for promoting new anime in a 16:9 landscape format.
