Sakura Asagi

Sakura Asagi is a Japanese animator, illustrator and mangaka.

She contributed her character design for the series Shōnen Onmyōji and Saint Beast. Apart from illustrating for the novel series Shōnen Onmyōji, she also authors the manga, which acts as a gaiden for the main story which serializes in Kadokawa Shoten's Beans Ace.

Even so, it is not to be confused with Hinoko Seta who authors the manga adaptation of the series in Kadokawa Shoten's Monthly Asuka.
