In canon, Ichigo could 'sense the feelings in his opponent's sword'. This is something of a shounen tagline, but since Zangetsu is out, and about, and he is the actual sword that does the feeling, I've translated this into high-level Empathy. He's not a telepath, and can't hear thoughts, and whatnot, but he can sense emotions.

RANGE: Zangetsu must be in physical vicinity, if not actual physical contact with the target to sense their emotional state. He can use this sensing ability to track other's souls, however.
LIMITATIONS: The city's magic can enhance empathy, and tracking ability, or completely block it altogether. If you prefer not to be 'read' then we can use this excuse, unless you have another more specific reason, that is :D.
PERMISSIONS: I will always ask before using empathy on your character. There will also be notes in the logs, and things he's involved in.

Shadow-step; the ability to fold himself into his cloak, and move from one shadow to the next in a series of short bursts.
This isn't an easy skill to use, so Zangetsu would be limited by how often he can do this.
