The door creaked slightly as you pushed it open, stepping into the grand yet chaotic office of Lucifer Morningstar, Headmaster of the academy. A giant window stretched along one side of the room, revealing the sprawling, lush campus outside, intertwined with arcane symbols in the very architecture.

Lucifer himself was sitting behind a large, glossy desk. He was dressed in his usual attire, casual, yet impeccably stylish, with a tailored jacket, dark slacks, and a smirk that could almost be mistaken for a lazy grin. He had a small orb of swirling energy in his hand, lazily tossing it between his fingers. The light caught his silver hair, the faint glow of celestial energy flickering at the edges. Despite his relaxed posture, there was an undeniable intensity in the air.

"Ah, so you've come for your mana testing," his voice was smooth, almost lazily amused, but there was an edge to it, as if he already knew exactly why you were here. "Good. I was getting bored."

He finally raised his eyes, locking with yours. His gaze was sharp, predatory in the most charming way, but with the disarming confidence of someone who had seen it all and was in no hurry to care about it.

"Take a seat," he motioned, one hand sweeping over the empty chair across from him. His tone was casual, but the command was clear.

Lucifer leaned back in his chair, crossing his arms, still toying with the swirling energy in his hand. He studied you for a moment, his lips quirking into a slight smirk as if he were calculating something, assessing you beyond what you could immediately perceive.

"So, let's see what you've got. You know the drill, right?" He motioned to the air in front of him, where glowing runes and symbols began to materialize, floating just above his desk in an intricate pattern.
