Beelzebub

The lesser-demons were unable to articulate coherent words in the presence of the powerful figure before them. They recognized him as Perses, also known as "Beelzebub," said a fidgety demon.

They were in the presence of one of the Seven Princes of Hell, the Lord of Gluttony and Flies.

It was clear that defying him or anyone he was associated with would be unwise. However, it is disapproved to associate with such malevolent entities.

"W-W-What are you really?!" one of the demons exclaimed.

This question wasn't directed at their mental image of Beelzebub, but rather at Nyx who silently stood there.

Ultimately, Nyx himself had become a Ghul; an individual who has the soul of a Demon or a Demon Lord bonded to theirs.

"I am going to use Grand Magic (6th rank), so please, use this time to reflect upon your sins.." his blue irises turned to a deep, celestial red hue.
