Honestly, I feel like if the series got axed right when Saki defeated Koromo, this manga would be a pretty good short story. Felt like the series went downhill especially when the Kuro dragon nonsense appear out of nowhere. Fanservice is cool but what's the point if the quality of the story drops. The current state of Saki actually reminds me of that onsen reincarnation manga, similar kind of anatomy, full of lewd art but subpar content.
