Someone from the AV Club

Oof!

Yuki and the unseen person collided and both stepped back, the impact not enough to make either of them fall. Yuki hit her head, so she was busy rubbing her scalp with her hands while her eyes were shut. The person she collided with was able to realize who she was, and more importantly, what she was wearing. However, we need to know who she's dealing with here.
