베이스 기타를 든 소녀와 디자이너 소년이 그려진 만화 표지

A vibrant Japanese comic-style cover illustration with two anime characters standing side by side against a split pink-and-blue pop graphic background filled with stars, dots, music notes, hearts, spark lines, and playful doodles. At the top, place a huge bold Japanese title in thick black and brown kanji with white outline and pink shadow reading 夜坂さんと茶藤くん, arranged in an energetic layered composition inside a fluffy cloud-like title shape. The left half of the background is pink and the right half is light blue, with a diagonal dividing rhythm and decorative manga-cover accents. Show exactly 2 characters from about mid-thigh up. On the left is a rebellious teenage girl with a straight black bob haircut and blunt bangs, pale skin, punk-rock fashion, and a slightly annoyed withdrawn pose with one hand near her mouth. She wears an oversized black zip hoodie over a red-and-black horizontal striped shirt, a red plaid pleated skirt, fishnet stockings, and a black heart-shaped choker. She holds a black electric bass guitar vertically across her body, with visible tuning pegs, strings, pickups, and chrome hardware. On the right is a cheerful teenage boy with messy light brown hair, fair skin, and a friendly expressive pose. He wears a white button-up shirt with sleeves rolled to the elbows, a fitted black vest with a small emblem on the chest, and black slacks. He holds a stylus pen near his face in one hand and a dark drawing tablet tucked in the other arm. Add exactly 2 vertical Japanese speech balloons: on the left, うるさいのはキライ。 in a pink outlined balloon; on the right, そのセンスもっとみんなに届けたいです… in a blue outlined balloon. Include small floating icons between and around them: exactly 2 black music notes, 2 pink hearts, 2 blue stars, and a few curved arrows and spark marks suggesting lively chemistry. The overall style is polished modern manga cover art, clean linework, glossy shading, expressive character design, bright pastel pop palette, high detail, commercial light novel or comic serialization cover aesthetic.
