Both Sagaras, the father and the son, are really childish, the old man even more so because due to his power nothing curbs him. Yet Miyuki is more petty by redirecting his ire onto Izumiko as he would get his ass kicked or worse if he really tried to go against Yukimasa. So, Miyuki makes Izumiko suffer instead and probably hopes that something will happen to her to teach Yukimasa a lesson. In fact I have to admit I was also hoping something would happen and the playboy would notice he's not as much of a knight as he thought. Yet I'm still happier Miyuki ended up going after Izumiko. Now that he heard such a grim prophecy I can only hope he will finally start to completely ignore Yukimasa and concentrate on himself and Izumiko instead. No doubt that would piss off an egoistic douche like Yukimasa far more than anything else (aside from getting beaten by Miyuki in a fight, but I doubt that's going to happen any time soon).

It's a damn shame Izumiko doesn't keep her hair free all the time. But I guess that makes her look all the better during the rare times she does.
