A giant flying ark crashes in the middle of Edo in the Keio era, leaving behind an enormous crater. Onboard of it were Rami Nanahikari and her mount - dragon Pochi. Rami is on the quest of gathering 6 jewels, scattered across Japan, because word is, the one to gather them all would receive a treasure. Her rivals are Doctor Pon - a tanuki with 1400 IQ and Yamatai Himiko - a queen of Yamatai Kingdom. A promo video for the eponymous Sega Saturn game. Part of the footage has been reused in the game and dubbed in English.
