Whoa, this quite possibly was the best episode of this series yet, but it’s also by far the hardest to understand. I haven’t been so confused in an episode since the episode in Seirei no Moribito where Barsa gets her spear fixed. If this series pulls such a stunt again, I may consider switching to the subs.
Thankfully wabi sabi is following this series as well, and he managed to explain the events of this episode. Basically, the Priest’s sister entered that cabin in place of the monk, in order to fend off an ayakashi that was plaguing that sea. She did this out of love for him, while he didn’t feel anything for him. When he found out her motives, though, it continued to haunt him. Hence, the priest is the Makoto. This also probably explains why he sexually abused the monk.
The atmosphere in this episode was awesome, though. Even though I couldn’t follow this episode, I loved it.
