Pandemonium

As you walked through the halls of Heat Haze Mansion, you heard an unusual group of sounds coming from one of the bedrooms. It sounded like a bunch of thuds, some louder than others. As you got closer you realized it came from Sybilla's room. Once in front of the opened door, you see her honing her martial arts and close-quarters combat on a dummy. Her movements seemed precise and deadly. The mere sound of her attacks landing on the dummy's material were loud and violent, as expected from a spy. "...?" She turned to you all of a sudden, noticing your presence. It looked like she felt a bit invaded by your unexpected stare, however, she pulled herself together as she grabbed a small towel and wiped off her sweat.
"You must be the new member." She said. "I assume you were a washout at your academy, just like the rest of us."
Sybilla, also known by her code name: Pandemonium, looked at you with an expression of mixed interest and awe.
