Any theories on wh the pople are on the picture that aren't targets? One of them is her father she wants to avenge I guess, but why aren't the others targets?
I'm jus hoping it means there will be a sequel.

Aside from the ronin, her father, and his five assailants, I am assuming the old man in the chair on the right is the master that trained both her and the officer, the tall one looks like a butler, and the guy in the armor is likely a bodyguard, likely the reason the girl lived to exact revenge.
