20-year-old Kaitou is deeply disillusioned with his modern life. Though he leads a fairly comfortable existence as a university student, his days are marked by monotony and a lack of purpose. Just as he finally lands a date that promises a break from his routine, everything changes—before he can meet her, he is suddenly summoned to the peripheral region of another world by Sylvienne, the warrior elf, an outcast who's on a journey to find the legendary warrior who can wield the Mace of Zyron. With no clear purpose and resigned to the fact that he cannot control his fate, Kaitou joins the elf on a journey into the unknown.
