Rikiō was Takeda Gohee's hunting dog.
Ginga Nagareboshi GinEdit
Gohee wanted a strong dog so he chose a Tosa.
Gohee fed him bear meat and Rikiō accepted it immediatly. One day, when Gohee went on a hunting trip, a bear appeared. Rikiō attacked the bear without hesitation. However, because he did not know what it was like to fear the enemy, he rushed the bear. The bear kills Rikiō by crushing his head with its paw. Rikiou dies immediatly from the blow.
