Zyl opens Blassreiter thus:

So, in addition to Mentar carefully anticipating and answering all my objections and worries (principally GONZO, then again Seto no Hanayome was enjoyable too - are they finally getting their act together?), there was also the invocation of the Shizuka Itou Doctrine for MOAR pink-haired kick arse goodness.

In contrast to the males, Amanda has been a constant pleasure to watch and hear over the first nine episodes that I’ve seen thus far. Particularly when she talks to Malek and Shizuka Itou says the Zaku trigger word, ‘Oneechan’, over and over again. Overall, there have been some surprises but the bigger, more interesting picture seems to be coming to the fore and I hope the series will go from strength to strength.

I'm considering it. The show is available on BOST, and I skipped it because it competed with Druaga, the Tower Of.
