Enthralled by a pleasant melody, the boy Suzuhara Sora accidentally opens his eyes in Japan during the Taise period. Not knowing where to run or what to do, Sora meets a strange stranger who is happy to help him in this difficult situation. All that remains is to find the ship hovering in the sky! Ah, could it be that he landed in the middle of a field? With a crew consisting of nine young men and three beautiful women, Sora will have to continue his journey through time on this vessel called "Norn". Where they are flying and what awaits them at the end of their journey is unknown to anyone, except for the occasional SOS signal from the "Mir" station.
