People make too assumptions that somehow become canon in their minds, and then they're outraged when the manga doesn't actually work like that.
It seemed obvious to me that when Yoru weaponizes Devils, it works roughly like Makima's control ability, in that she gains access to their abilities. Perhaps even to a greater extent as Makima never showed Gun's ability to turn body parts into weapons like Aki as Gun Fiend and Yoru now have.
This makes for some interesting possibilities if Yoru ends up weaponizing other Devils.

Duh, that's because Fujimoto himself drew Gun Devil/Fiend with such weapons ages ago.
This is just the first time Yoru uses Gun's power properly to its full extent.
