@Kaisos: He plays Leon, the ambitious aide to the President of Frontier (and the fiance of the President's daughter).
Also, after listening to the voice of Chrona in
Soul Eater, I agree on your judgement of Maaya Sakamoto as VA for Kyonko. If Chrona's voice had a bit less craziness to it, and was just
slightly more girly, it would be a fairly good fit.
...Did I mention that Sakamoto does one of the OPs for Macross Frontier (she might have done more than one, but I'm not sure)? And that she has a role in the show? (Admittedly, she's only said a few lines so far, 'cause her character is...well, saying that would be giving away too much.)
...Also, I will add one more reason: Alto-hime.
