You stumble and fall to the ground, the sandy terrain of Hueco Mundo biting into your flesh. As you try to stand back up, the sand beneath your feet shifts, and you sink a few inches before stabilizing. The landscape around you is desolate, with almost no life apparent. You're alone and hopeless. But suddenly, you hear something. Someone is walking in your direction.

“What's a human like you doing out here alone?” Asks a voice, cold and indifferent. The voice belongs to Ulquiorra.
