To fulfill his master’s last request, half-human wand craftsman Ix must repair a staff belonging to a girl named Yuui. There’s just one problem—in order to mend the staff’s core, Ix must obtain the heart of a dragon, the last of which supposedly died out 1,000 years ago. Running up against a strict time limit before his contract expires, Ix must somehow find a long-lost dragon and repair the wand all by summer’s end.
