(masterpiece, high quality, ultra-detailed) A feminine artist's signature in a stylized format reminiscent of signatures found in anime, manga, hentai, and manhwa art. The signature elegantly writes the name "Yua Tsumugi," seamlessly following a delicate, curving line that resembles the sketch or outline of a character drawing. The writing flows beautifully, with a soft curve and a natural, fluid motion that integrates into the design, resembling how signatures are often incorporated into the linework of illustrations. The background is white, highlighting the elegance and artistic style of the signature.
