A Mazoku in charge of a kingdom is VERY bad, because then they can do things more directly to people. Imagine if a demon was in charge of China, err, bad example. Imagine if a demon was in charge of the US, err, probably another bad example, but, yeah, just imagine if a powerful country was being led by a demon.
Zest is only slow compared to super speedsters. Considering that Nanoha is slow compared to Fate...
Yeah, Luke is that bad. As for Zest, nah, people will just wonder "hey, where did he go?" XD
Don't worry, she's only just starting. Yuuno, when he got his power up, had magic experience by that point, Arisa's completely new at this. She'll get better. Or Luna'll kill her in training. One of the two.
Heh, slightly more sympathetic, but he still has his desire, it's just tempered due to memories of Al Hazard that suddenly came up. =O
Well, let's hope so. BTW, how do you think I handled Amelia there?
