[Aigis was quite literally built for this. The darkness is no worse than the Dark Hour, the monsters no harder to deal with than Shadows. She always introduces herself as a weapon but today may be the first time she seems like one rather than just a sweet and curious robot girl. She cuts through every creature she encounters, switching effortlessly between her own physical attacks and her Persona interchangeably, darting from threat to threat. The first time she encounters a fear spot she slows, analyzing it for a long moment before determing it is no real threat, just something like the panic Shadows sometimes create. She can more through it, it won't slow her again.
She should be easy to find; just follow the flash of her Persona in the dark, or the sound of gunshots. Or the trail of monster bodies.]
