The Totsusa Kingdom (or the Totsusa Empire (兎津叉帝国 Totsusa Teikoku) in the manga) is a kingdom located on the moon. It is ruled by Artamos.
The kingdom used to be on good terms with the Sea Kingdom.
The kingdom launches an invasion on the Sea Kingdom after the princess receives a threatening letter supposedly from Uomihime.
The kingdom was never seen (only mentioned in the game) in the game or any other official source.
Up to this day, no location of Totsusa Kingdom was ever shown.
