This manga is doing a great job shifting the narrative away from Toregene and Fatima and slowly building up sympathy for the Mongol princes trying to hold together their empire. You can't help but root for Guyuk to strike back, or for the budding historical alliance between Batu and Mongke to later decide the fate of the world. I was worried about it because this is supposd to be Fatima's story, but even in this manga the princes are becoming the great Khans they would be remembered as. Fatima is really starting to come off as the witch.
It's also doing a bold job remembering that, unlike in later Western historiography, from the Mongols' own historical memory Batu was actually in charge of the expedition at this stage and wasn't just some figurehead for Subutai. Eastern European chroniclers (especially Soviet ones) tend to lionize Subutai because he was being used as a precursor and model for the WW2 heroes of the USSR, particularly Zhukov, but Mongols remembered things differently.
