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. Hoping for permission to line the roads between the wintry cities with the glowing phostyrias plant, Shirayuki, Obi, and Ryu arrive at the Oriold checkpoint. The knight captain there won't stand in their way, but due to political instability in the northern region, they'll have to win over a certain Lord Lugiria. Deep in uncharted territory, can they light a path to the future?
