@PrimezTime: It's why only a skilled summoner would do it. They can, as well, also be partially summoned, they are carefully bound by the summoning... and on top of that there's rarely a reason to summon something so powerful. Still, there are other powerful summons not on that level that range in how they will cooperate(many depending on how powerful the summoner is), and others are more animals than anything.

Basically I'm still not really sure a mechanical warrior army like that sits well with me.

@Asuras: There's a city watch, which Rin has been working on like she said, eh-heh.
