Okay, I understand why we need this flashback in full now, as it tied what's happening with the Keikain clan right to Nura clan. And we also get to see why Rikuo is the way he is, as we basically traced his family tree lol. The fight scene was tense and fun, I like the callback to last episode too, where Princess Yo cuts Nurarihyon. And as someone who loves a cute love story, I think Nuraruhyon's and Princess Yo's relationship is cute, even when we only get a little window to their story.
