Miya and Kon are siblings who were raised by a carpenter's master on a small island in another world. During the two years that her master left the island at his request, Miya grew up like an ordinary human girl, but Kon has not grown taller since then, and his ears and tail, characteristic of demi-humans, have become more prominent. The two have been together without suspecting that they are real siblings, but they begin to feel doubts and anxiety about their different appearances. An apprentice carpenter girl and her little brother, Chibi Danuki, find their destiny in the way of two people who want to be a force for the people of their beloved island !?
