Katsura Kotaro of Choshu and Saigo Takamori of Satsuma. These two would be the lyncpins of the Joi revolution that disposed of Tokugawa rule, but they didn't always get along.
I'm gonna go get Saigo-don, so 
make sure you two get along!
¡Debo traer a Saigo-don
para que se lleven bien!
Vou trazer o Saigo-don aqui pra
vocês dois fazerem as pazes!
