Well, you can't make an omelet without breaking a few units and potentially some friendships. In the case of Anya, I think she handled it well. (What of Minami now, then?)
But the case of New Gen, well... THE WRECKING DRAMA TRAIN HAS NO BRAKES RIGHT NOW. Rin went ahead without some consultations from her unit. Thus, Mio just went in and added fuel to the engine. What of Uzuki now, then? I mean, what the fuck? She's average and she knows that much is true, so I'm pretty sure this would be a source of angst for her: Without the other two, who the fuck is she?
I honestly feel like Miss Mishiro's restructuring is being too hard to the company, but I think it is justified in this case when it comes to the company.
