We finally get the whole picture of that flashback that had been teased since the first episode. The full story felt bittersweet and understandable. It is sad hearing how she became Hagoromo's vessel, which is why I understood why Rikuo reacted as little as he did. Even though we saw little of Rikuo's father, I feel like I understood his feeling, even until when he died, which is sad, in a way. With that being said, I think that ending was more than hype enough for the finale after this, which is making me pumped!
