Leo had been working hard on the other side, trying to figure out who would've possibly been messing with his system, when he discovered a variety of changes that had not been done by outside interference.
The system was never designed to be given to demons, it could not measure demon energy or process anything related to demons. But after it had an unprecedented encounter with Alice's demon energy mixed with the saint's power, it started to undergo changes.
A system had not been granted to Alice yet but with Leo's interference, a virtual one being managed by Leo was assigned.
It wasn't permanent but for the time being, before it was time to receive her original one.
And that system, being managed directly by the creator itself, went through a certain evolution.
It evolved to help with this particular Human's natural demon energy. So, to help Alice's future growth, the system had a special feature suddenly added by its artificial functions.
