ダンジョンに出会いを求めるのは間違っているだろうか ─ オリオンの矢 ─

Living above the legendary dungeons of Orario ought to be enough danger for anyone, and in his short time as a member of the goddess Hestia's familia, Bell Cranel has experienced more perils and pitfalls than most. So, when Bell unexpectedly wins a free trip, is it too much to hope that he might have actually won a real vacation? Of course it is! Inexplicably chosen as the champion of Hestia's friend, the goddess Artemis, Bell quickly finds himself up to his neck in ruins and monsters as yet another epic quest begins. And where Bell goes, can the ever-jealous Hestia be far behind? (Source: Sentai Filmworks)
