Anime Light Novel Cover

An anime-style promotional illustration of 3 characters running forward dynamically amidst a joyful painting scene under a bright blue sky with fluffy clouds. On the left, a blonde young woman in an elegant white ruffled dress and gloves smiles brightly, holding a paintbrush dripping with pink paint. In the center, a black-haired young man in blue overalls and a black t-shirt looks excited, holding a roll of masking tape and a green paint roller. On the right, an older laughing man wears dark traditional Japanese work clothes with a white towel around his neck. Colorful paint splatters fly through the air alongside floating props including 2 paint buckets, 2 paintbrushes, and 2 rolls of masking tape. At the top is a stylized title logo reading {argument name="main title" default="お嬢様は塗装を知らない"} decorated with paint splatters. Below it is a banner ribbon reading {argument name="subtitle" default="清楚なお嬢様 × 塗装男子"}. At the bottom, a bold tagline reads {argument name="bottom tagline" default="未知の世界でふたりの距離が縮まっていく…！"}. The style features vibrant colors and a light novel cover aesthetic.
