Also, even in the dark, it's pretty easy to 'see' a mechanical dude if a pack of wolves who CAN see in the dark are circling him. They aren't doing so silently, not by any means. I imagine that the barrage of bullets probably mistakenly took out a few wolves as well, but losses are worth it for such a catch. To be honest, Kami was kind of screwed anyway, no matter how powerful your character is, no one should be so powerful that a room full of enemies can't take them out when he is pretty much their singular target.
