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 track Kageya and Ryu to their supposed whereabouts, but all they find is an empty house and signs of a scuffle. A conspicuous clue leads them to believe that Kageya has a secret greenhouse where she concocts the antidote to the menacing perfume, so that's their next stop! It's time to snuff out the unsettling aroma that has enthralled the northern lands!
