Fifteen days later.
After continuously searching around the cities that could potentially house the Black Sorcerers, they still had no clue about Lefay's whereabouts. Grimm's patience was wearing thin.
From what Nina had described, there was something peculiar about these black apprentices. They seem to have appeared out of the blue in great numbers.
They shared nothing in common and there wasn't any pattern that could lead to a clue. They have never even interacted with each other before.
Although the black apprentices were a menace, they were no match for a proper sorcerer. They could simply hide like parasites within the blindspots of the sorcerer academies.
The terrifying Black Sorcerer, Hattori the Hidden was another matter, however.
Not only was he the source of the increase in the black apprentices, but the Holy Tower of the Seven Rings even recorded six cases of real sorcerers who were murdered in his name. One of the victims was a demon-hunter who was on duty.
Be prepared for an emotional roller coaster ride.
