Ernst mixes the blood of Rin and Yukio to open the Gehenna gate, but the Messiah weapon proves ineffective. A swarm of demons bursts forth from the gate, along with Satan. A flashback chronicles how Rin and Yukio’s mother Yuri became mixed up with demons to the point that Satan joined with her and gave her twin sons. Her own father Ernst was going to burn her at the stake, but Satan intervened. Fujimoto and Pheles were sent out to kill her and her demon spawn, but Fujimoto can’t do it. Back in the present, Ernst is sucked into Gehenna, while Satan possesses Yukio.
Yukio displays baffling naivete, Ernst lets out an evil laugh as he describes his diobolical plan, and Rin screams in that horrible way he screams that’s worse than nails on a chalkboard. Not a good start for the penultimate episode. I was also worried when the flashback had a flashback – nothing kills the thrust and momentum of a story in the present like a tangent into the past that occupies most of the episode. The series would have us believe that this story had to be told in great detail, but I for one was fine with some of the past being unknown or muddled. Some mystique was lost.
Also, if being possessed by Satan turns Yukio into such a wild, raging maniac, why does that same satan so calmly and vividly tell Yukio the story of how he and Rin came to be? He’s Satan; the ultimate unreliable narrator. And while he’s busy telling this intricate tale, the other characters are sidelined, doing absolutely nothing. So now, we have a Satan-possessed Yukio, who’s screaming a lot, but at least his screams aren’t as awful and shrill as Rin’s, but of course he’s upset, so he’s screaming too. I would hope that next week’s finale has a minimum of screaming, but I’m not going to hold my breath.
