A Denji poster with a gradient art style and a yellow background would be a vibrant and eye-catching piece. The poster features Denji in a dynamic pose, perhaps mid-action with his chainsaw arms at the ready. The gradient could start with a bright yellow at the top of the poster, gradually transitioning to a darker shade of yellow towards the bottom. This type of poster would be perfect for fans of Chainsaw Man who are drawn to bold and energetic designs.
