You can't have a revolution without muscle, and nobody during the Bakumatsu had more muscle than Saigo Takamori. See how the big brother of the Meiji restoration helped take down the Shogunate!
I've gotta come up with a way for Saigo-don 
and Hisamitsu-sama to get along...
Debo hacer que Saigo-don
y Hisamitsu-sama se lleven bien…
Preciso que o Saigo-don
e Hisamitsu-sama se deem bem...
