one thing I adore about the time they go to the empire to find the Facsimile Ramus is the way that every single facsimile is drawn with so much more humanity than the main cast.. they're way more realistic, which I think is to emulate a sense of uncanniness.
We as readers are so used to the classic manga style with less detailed faces and fluffy hair, but then we get faced with a sallow faced man and the endless copies of him... And since they're all copies of the same person they have to feel at least a little uncanny to look at
Don't get me wrong, the artwork we see through most of the manga is a blurred line between realistic and not, the detail and realism on buildings and wagons and landscapes is genuinely brilliant and facinating- but the people tend to look like anime people, even when they're making strong expressions.
But not the Facsimiles....
They don't have the simple noses and flat faces. You can see every crease of their skin even when stylised.
Along with it being all uncanny and that I do think, though I may be stretching it here, that they're meant to feel more human.
The Facsimile Ramus has such a strong personality and that rubs off on every single one of his copies, they are caring and thoughtful even if they don't realise it. Like as soon as one of them gets asked "Why did you become a soldier?" They spend the rest of their life contemplating "Why?" Even though they sacrifice their kin and build a hierarchy based on scars on their head... They're very much individuals. It's unfortunate they only know what they're created to do until something else sparks their mind.
Very refreshing when it comes to the Army of Clones trope, there's obviously a lot of thought put into this.
