I knew about it before, if that's what you wanted to know.

[Ankh knew because he had been told a while back by one of the older gods. And when he found out his shinki was none other than Eiji, he wasn't going to chance it. Sure, there were a few things about his temple and the candriod showing up that was uniquely from their world, but Eiji acted like he didn't know what it all meant. And that was fine with Ankh so long as he was still living of sorts.]

Still, you think that they would have done this before the rampages.
