てんてこ温泉時代劇 ～亀屋～

Kenta is the third son who runs a shop in Edo. One day his parents become owners of a bankrupt hot-spring ryokan "Kameya" and insist that Kenta assists them here. Kenta only agrees to leave Edo on condition that he would return if can successfully restore the ryokan in a year's time.
