While in deep thought over his meeting with Izana, Zen has a little accident and is slightly injured. Mitsuhide seeks help by the Chief Herbalist but while in her office accidentally knocks a bottle over and inhales its contents. Because of that a deep part of Mitsuhide's personality emerges, making his loyalty towards Zen extremely strong. During the following days Mitsuhide refuses to leave Zen's side, driving him crazy. Eventually Shirayuki finds the antidote that allows Mitsuhide to revert to his normal self, albeit losing any recollection of his recent behaviour. Thanks to working out the cure, Shirayuki passes her exam and is becomes official court herbalist, ending her apprenticeship. Shirayuki is pleased, but remembers that soon she must make a decision regarding the future of her relationship with Zen.
