I'll probably keep my thoughts about this route short as I want to package it altogether after I finish the Demon route (which seems more like an epilogue than a full route) and what I assume will be the ending of the VN.
Really there's few words to describe it as anything less than incredible from start to finish. The twists are just so insane and over the top and never once really did this route let off, even during our brief stint with Kag
eggaki and Chachamaru during the Green Dragon Society meetups and the war. I can see why people thought the latter would drag, but for a VN that's spent a very significant amount of it's time being much more of a personal story who's strengths lie upon it's honestly unmatched character interactions, it was nice to have that perspective change for a bit. It was refreshing for me, but for those who wanted to see how the story would progress next after that huge plot bomb in Hikaru's room, I can see why they'd feel it start to drag a bit.
Like I said, I'll have a bigger writeup once I hopefully wrap everything up soon, but as for the tl;dr of how I feel about it now, it's definitely my favorite of the main routes and god the highs were just so damn high, and the narrative was absolutely at it's most devastating here. It was hard not to get real choked up with that scene of Kageaki and Chachamaru underneath the tree, or Muramasa meeting a blind Tadeyasu who discovered she was responsible for Yuhi's death, or at the very end, Kageaki finally showing Hikaru the love she was denied from her birth by her parents/clan. It's gonna be hard to sleep tonight because I really want nothing more to finish the novel as I can't really stop thinkin about it right now.
Also that puzzle took me 4 fucking hours to solve, that was legitimately one of the most difficult things I've done in a while, but god damn did it feel relieving to do it without a guide.
