Fear
An emotion the Kerberus didn't even know about.
After all, it was a S-rank monster and the strongest in its lair, with the sole purpose of protecting the ritual altar.
If anything, others were supposed to fear it instead of the other way around, and yet as he saw the boy who had entered the boss room, it felt afraid.
It wanted to abandon its duty and run, but due to the way it was born, it ignored its survival instinct and prioritised the protection of its master.

The kerberus let out a fearsome roar to scare the white-haired boy, but instead of that, its roar had the opposite effect, as William said.
"No need to scream, little puppy," William taunted, and despite not understanding him, the Kerberus knew it was being mocked and unleashed its strongest fire attack at him.
