Summer Time Rendering Ep 12

This is easily the best episode I have seen SO FAR of this anime.
Holy $hit, that turned into some serious stuff in the last 8 mins.
Demon was BLASSSSTTTIIIINNNNN
LOL, how many headshots went down? #Sheesh
The plot is getting quite cool. I forgot to talk about the mother of the shadows at the end of the episode. That is a pretty cool and scary origin story. Am I understanding it correctly that Haine was the first human to be copied by shadows? Did they say how long ago that was?
