He once said that a generally simple mechanism device is doable, but complex things like smartphone isn't... something that use a chip or processor, perhaps? something that used very advanced technology?
But, then... how about 'forging' a missing/lost body part? then again, if it was possible, it will return to nothingness after Kaname's conscious control got released...

So far, his ability seems to only go as far as to create anything that has already existed within the limits of synthetic and natural material, and *doesn't hold too many complex mechanisms*.
I think the issue with the smartphone is that the complexity factor included electricity. So while he could theoretically create all the physical components to a smartphone (the wires in every form of metal they come in, the plastic casing, etc...) it wouldn't work because of the electricity needed to run through it.
I think this implies that the reason his power, while kind of OP, isn't god-like is because he has even more limits on "natural materials"? Things like wooden swords are obviously no problem for him (given the recent chapter), but I guess the more intricate functions are impossible for him. He might be able to create something out of pure bone, but flesh and nerves and muscle + electrical synapses to get the body part actively working to any capacity doesn't seem possible for him.

I wonder why the manga and anime industry nowadays are filled with harem-esque story...
It's not that I hate it, it just that I don't like it... so much fan-service that it diluted the essence of the story.
I don't mind ecchi and smut, really... but not cheap and bitchy one.
Hope that this one won't go down that path too deep....
Just... LOL
