Looks like the idea to reverse engineer the pills was shot down pretty quickly. Meanwhile, the secret organization seems to be preparing for something. They mentioned something about a century passing from finding the alien ruins, so maybe it’s supposed to be some sort of ritual sacrifice that involves the witches? It would make sense with the message that Kazumi translated at the end of the episode.
So, what happens now? I assume the mad scientist guy will find out what exactly the “fertilized alien egg” is supposed to be. Also, I guess the gang will go investigate the spot indicated on their treasure map. Nanami seems to be the name of the next witch to be sent after the group…is that a different witch than the legendary “Valkyrie” they mentioned this week? And what link does Valkyrie have with Kana? She reacted to the name…I’m still suspicious of her.
