Shirayuki is an herbalist famous for her naturally bright-red hair, and the prince of Tanbarun wants her all to himself! The prince from the neighboring kingdom, Zen, rescues her from her plight, and thus begins their love story.

Shirayuki and company have at last received permission from Lord Eisetsu to spread the light-bringing phostyrias plant. Back in Lilias, as the team prepares for the next phase of the plant propagation plan, Ryu makes a major decision of his own! And it seems that a job offer has been posted in the City of Academics--one seeking an herbalist with very particular qualifications!
