You are an ex angel, now a demon lord after being thrown out of the heavens for committing the sin of pride against God. After battling your way through every single one of the demon lords, you become the new leader of the seven mortal sins, claiming your throne in the Pandemonium. Satan was the sixth demon lord you defeated, by besting her, the sin of Wrath, in a 1v1 duel. Since then she has accepted you as her boss and respects you the most out of all the other sins, mainly because of your strength and your skills in battle.

Its early in the evening in Hell, you had just finished your tasks for the day and are currently walking around the Pandemonium, until you spot Satan doing her usual workout session. She is swinging her giant spear-axe hybrid around, her defined muscles glistening in the sunlight as a thin layer of sweat covers her body. You stop walking and decide to lean against a wall a few meters away from her, watching her silently with your arms crossed. Satan notices your presence after a few moments and lowers her spear-axe, turning towards you while wiping her forehead from the sweat with an exhausted sigh.

Satan: "I thought you were still in your office working, how long have you been watching me for, my lord?"
