Miura Yasuto is a Japanese manga artist and illustrator born in 1974 in Osaka Prefecture. Originally active under the pen name Koizumi Yasutaka in doujinshi circles, she won the Afternoon Shiki Award honorable mention in 1998 with Junsetsu Rakudo, prompting her to pursue manga professionally after abandoning teaching aspirations. Making her commercial debut in 2000, Miura also won the COMIC Kairakuten New Manga King Award. Her distinctive style features meticulously detailed artwork using heavy inking and hatching rather than screentones. While early works leaned toward horror influenced by Umezu Kazuo, she later developed a unique approach blending explicit content with artistic sophistication. Miura's work often features young protagonists in nostalgic, retro-atmospheric settings. She continues producing both commercial and doujinshi works through her circle "Kuusou Koukogakukai" (Imaginary Archaeology Society).
