System develepos a humanoid interface after 180 chapters...man, they really thrown the original script out of the window.
This is probably a way to keep readers with fanservice, I'm sure they lost several viewers with the change to the story following the art swap.
Very dumb, the system was originally intoduced as a way to MC to get better and punishing crooks but now he will probably get some big objective/mission from it.
They returned on the assassination arc against that heroine so to end it fast and then get the MC on his own mission, as they forgot to touch it for hundred of chapters.
