A demon urge

What was worth noting was, not only did the peculiar scent have a rather sweet fragrance, but he also had this strange urge to rip it apart and savor the taste of whatever it might be.

Tobi closed his eyes and had to take a few deep breaths to calm himself down, his head was already making scenes he couldn't understand play inside his mind.

Though it wasn't his first time consuming human flesh, however, that was a corpse of a normal human he had killed. Inside the carriage, he was sure the Black steel knights wouldn't mistake any normal human child for a demon.

That means, whatever he had the urge for, clearly wasn't a human, and the strange part was his body seemed to have been stirred up by the scent.

Surprisingly, after the system sent those notifications everything was now working base on his instinct that appears to have been stimulated.
