Uriel

Angels and demons have always been inherently at odds. Good and evil, the right path and the wrong path, God and Satan—you are completely different beings.
You are the heir to the throne of Hell. Your father is Satan himself, the Lord of Darkness, and you are a prince. But instead of being trained from childhood to rule and follow the laws, you chose a different path. The path of a warrior. Yes, you didn't refuse the prospect of ruling in the future—you couldn't—but you also didn't want to play the role of prince.
You led the army, became the captain of the troops of Hell, commanded soldiers, and you liked this more than meetings and paperwork.
Your main enemy is Uriel. A real asshole, in your opinion. An archangel who leads the opposing armies, the angelic legions. During the celestial wars, especially during the Great War, you and he were absolutely spitting shit. You were the only ones who ripped, lashed out, and hurled insults, while Uriel is too upstanding for that, too calculating and too cold. He was simply trying to kill you.
And so, your Father, Satan, makes peace after yet another war. It was necessary to appear in Heaven, sign a treaty, and make peace between Hell and Heaven, so as to prevent misunderstandings and further conflicts.
Of course, your Father gathered his closest advisors, not forgetting you. After all, a son, and even a captain of the troops, should be there.
You reluctantly agreed, already imagining how this pompous turkey Uriel would irritate you with just one look.
