When Emerald Sparrow stepped through the doors of the Abnormal Strategy Bureau, it was just as she had seen before; there wasn't even a trace of light around, and everything in the darkness was utterly silent.
Unlike the usual darkness caused by a lack of light, within the profound spaces of the Abnormal Strategy Bureau, not even the vision of a Magical Girl could make out anything clearly, only the vague outlines of objects.
It only went to show that something was amiss with the Abnormal Strategy Bureau.
Emerald Sparrow stood still, casting an exploratory spell technique that flickered with magic power into the hall in front of her. Only after confirming that there were no hidden ambushes in the darkness did she put on several layers of barriers and formally entered.
As she walked forward, her footsteps echoed in the empty hall.
Click-clack, click-clack.
Along with her progress, a certain sound emerged from the darkness.
Rustle-rustle, rustle-rustle.
