Mochiko Slice-of-Life Comedy Poster

Create a bright, soft-toned anime promotional poster for a fictional slice-of-life comedy series. The composition is a single-page Japanese anime main visual with a female protagonist at the center, surrounded by five illustration moments and Japanese promotional text blocks, presenting the style of an anime promotional poster. The protagonist is {argument name="character name" default="もち子さん"}, a cute anime girl with short white hair that gradually turns silver, bright blue eyes, soft blush, and low twin ponytails tied near her shoulders. She wears an oversized black hood shaped like a lop, a pair of round silver goggles perched on her head, a black collar with metal round decorations around her neck, and a futuristic black-and-white off-shoulder crop top adorned with a small badge on the chest, a detachable black sleeve, ultra-short white shorts with black trim, a single-leg leg strap, and a small side bag at the waist. Her body proportions are designed in a youthful anime style, with a slender and petite figure and a slightly exaggerated bust, presenting a refined modern cute character design. She stands at the center of the frame, wearing a gentle smile, holding a pen in one hand, as if preparing to make a mistake while writing, facing the audience with confidence and sweetness. Around her are five small illustrations of the same character's supporters: 1) In the top left corner, a chibi-style scene where she is outdoors, hands stretched forward, mouth wide open and dramatically crying; 2) Lower left, comedic scene, where she is exhausted and panicked, lying face down on a table or floor, surrounded by scattered papers; 3) In the upper right corner, a bust holding a card with Japanese written on it, her expression apologetic; 4) In the lower right corner, a cheerful half-length portrait, eyes closed and smiling, one fist raised as encouragement; 5) A small background portrait behind the text in the upper right corner, used as a character annotation. Near the center of the bottom are two small white mascot creatures, round like mochi, with small dotted eyes and small mouths, one large and one small, floating or standing beside the heroine. Soft spring tones are used, including pink, sky blue, mint green, peach, cream, and white, with cherry blossom petals and rounded graphic shapes scattered in the background. The background should create a light and festive atmosphere, with subtle outdoor landscape blurs and decorative curves, stars, and bubbles. The poster is filled with playful commercial anime-style Japanese layout: a large multicolored title in the upper left corner, subheading text above, a red seasonal broadcast announcement, a pink "あらすじ" (plot summary) box with multiple lines of text on the left, a blue description box in the lower left corner surrounded by vertical and slanted exclamatory phrases, and a pink production staff list block in the lower right. Add a prominent character name banner in the top right corner. All text should look like authentic printed Japanese promotional copy, headlines in rounded and colorful fonts, and smaller text in a concise magazine-style font. Overall atmosphere: cute, comedic, slightly chaotic, professionally designed anime main visual suitable for 16:9 landscape format new anime promotion.
