character: echidna_(re:zero), A medium shot from a slight 3/4 view featuring Echidna from Re:Zero in a cosplay setting, standing centrally. She has very long, flowing white hair with distinct strands between her eyes and a delicate butterfly hair ornament, paired with her characteristic purple eyes and colored eyelashes. She is dressed in a Demon Slayer uniform inspired by Tomioka Giyuu, consisting of a dark brown gakuran-style jacket over a white shirt and matching hakama trousers, completed with a distinctive split-pattern haori draped over her shoulders. She stands in a poised, neutral stance with her hands resting naturally at her sides, wearing a calm and mysterious expression. The background is a simple, out-of-focus traditional Japanese garden with soft greenery and stone paths. The visual style is a high-quality anime illustration with clean line art, soft ambient lighting, and a balanced color palette that emphasizes the contrast between her white hair and the dark uniform.
