The Tendoshu and Yatagarasu swoop in for the kill after the Shogun and Hitotsubashi factions wear each other out.
They knew everything, but 
they played the silent observer
كانوا يعلمون كل شيء لكنهم راقبوا في صمت
Lo sabían todo y se limitaron 
a observar desde lejos
Eles sabiam de tudo, 
mas ficaram só observando
