The students barracks shook slightly, almost unnoticeable, except that the small glass of water on Nana's night stand. Her hand had been positioned over it in a manner as to grab it, but the shaking began before she'd touched it. Both eyebrows raised high before she climbed out her window and shunpoed to the tallest building next to her own. Her eyes caught sight of the almost black dust falling from the air where two buildings had just been leveled. She'd been training only moments before stepping into her room, so she had her sword on her hip, and she took off in the direction the commotion was coming from. Of course using the roof tops made the trip that much quicker, but once she hit the ground she was met with a girl running with something balanced on her back. 

Stepping out of the way, Nana looked at the horns that were visible over the beings head, a look of confusion on her face. With a quick look around she shrugged and run up behind the two, shouldering the things other side so that it wouldn't be so heavy on the girl. She might be a Shinigami but having another person just hanging from you could be troublesome. Without speaking she followed where ever the other girl was going.
