hontou ni sou omou?

Himeko and Chikane are informed that about the legend of the Orochi - an evil god who is sealed by a shrine on the moon and the shrine maidens of sun and moon who are to defeat him - by Souma’s elder priest brother. Overwrought by her status as Hi no Miko, Himeko tries to run away but is intercepted by Chikane who reveals she is the shrine maiden of the moon (Tsuki no Miko) - so they’re both in the same boat. An Orochi minion arrives to ruin the romantic mood and beats down Chikane. Souma arrives and saves the day again.

L: Kiyohime, dark serpent of repressed desire, Child of St Shizuru of Lesbos.
R: It is the name of an ancient fate. Two maidens with black hands. The peace of the newly born, their dark arms protect.

Given the ED and OP, one would assume that Chikane and Himeko will get together and from Ep 1, it’s abundantly clear that Chikane fancies the panties off Himeko. However given the dynamic that’s been set up - a clear and present danger, no miko powerup yet and Souma with the big robot to the rescue, I was thinking that C & H are only ever going to get together if they can unseal Ame no Murakamo (and thus reduce their dependence on Souma).
