The blade familiar of Takeribi who has raised Sakuna in her parents' stead.  His true form is the Blade of Hoshidama, the strongest holy sword in the land.  Unfortunately, this legendary blade was broken in half during the battle with the evil god Omizuchi, and Tama has been unable to perform his role as holy sword ever since.

In addition to being an invaluable source of wisdom and advice, Tama can also facilitate communication with the Mihashira Capital.  Once you have reestablished relations with the capital, speak with Tama in the house to trade your rice for materials and other goods.  After you have made a purchase, traded items will be deposited into your inventory the next day.
