"I would prefer it if you just called me Azrail," the slightly perturbed scythe-wielder asked Mephis. It seemed as if the whole thing was just an act. JUST AN ACT, THAT'S IT!, Azrail thought as the sudden realization hit him. He had heard of the famous Galileo, but his last name was almost always left out. The androgynous magician had tricked just about everyone in the school on more than a few occasions, and Azrail had just been added to their number. The lightning reaper chuckled under his breath and said, "I'm sorry, but I won't be joining you two for tea. I have more pressing matters to attend to." Azrail decided not to reveal who Galileo was, decided to let the harmless trickster have his fun. People like Galileo added a bit of eccentricity and lightheartedness that Azrail appreciated; it's certainly difficult to keep up such a happy demeanor in the face of the world's atrocities.
Azrail reached out his hand to shoot a spear/chain up onto the roof when a sudden screaming ran through his mind. No, not his mind, his soul. Azrail's aura began to visibly shimmer and shake as he clutched the sides of his head in a futile attempt to block out the noise. He dropped to his knees and writhed around uncontrollably as a roaring snarl split through his everything. He almost asked for help, but then he knew they couldn't hear it. Neither of them seemed particularly in tune with their auras, and even then they'd have to be aware of the source. Azrail knew he had brought this upon himself; it was the result of countless hours focusing on this one unknown, the result of obsessing over it. The aura-based screech left almost as quickly as it had appeared, but in its dying moments, Azrail could make out the direction of origin. He leaped to his feet and left in the direction of the airship platforms without an explanation or a word.
From an outsider's perspective, the whole incident had taken no more than a few seconds. Azrail had silently clutched his head spazzed out on the ground, and then stopped. It was probably better this way, Azrail figured. Better that everyone thought he was a nutcase. Better, of course, than trying to explain everything. Better than begging people to understand.
