Yuki, a Kitsune, yearns to be an adventurer, with grand ambitions of making it easier for others to follow in the adventuring ways. Her Father, a veteran in the field, never came back from his last assignment from the newly formed G.U.I.L.D. (Global Unified Institution of Learned Daredevils), but his sword did. On her 18th Birthday no less. That day, Yuki decided to start her journey at one of the only two G.U.I.L.D. academies in the world. What challenges await her? What changes does the academy hold for her? What happened to her Father? These questions plague Yuki's journey to the Academy.
