Miroku and the Mantis Youkai

"Miroku Walks into a Dangerous Trap". A praying mantis demon disguised as the princess of a destroyed state lures Miroku away from the party offering to bear his child, then attempts to eat him. He destroys the demon with his Wind Tunnel, but its forearms nick the edges, prompting the main plot of the episode.
