Luna knows there are magical creatures that exist in their world as she's already met one in the guise of a sylph.  That being said she can't help but want to believe Yesung's claim there is a unicorn in the forest behind Henry's house, as unlikely as it sounds.  Completely unprepared, she sets off into the forest and promptly finds herself quite lost.  Will she find the unicorn she wants to see so badly or return home, if she can find it, the worse for wear?
