First Challenge of a Noblesse I

The Noblesse Inner Demon of Adrian is indeed different from the others that a normal Daemos would have. Normal Inner demons are what people will describe as demonic because of their brash and destructive nature. It is also an alter ego of the Daemos if they lose control of their own power. It is what takes over a Daemos temporarily when they fail to defeat their inner demons to attain a higher Persona.

An inner demon that is intelligent is really out of the norm just like what Adrian has. It is not normal because intelligent inner demons that have full control over instincts can wreak havoc and untold destruction. Unlike a normal inner demon that would usually just rampage and destroy the area around them, an intelligent inner demon meant they could even manipulate the real ego into doing things without being noticed.
