Ok, that makes sense.  Tell me, would she be able to tell that Light's character was undead, or just get an uneasy feeling around him, or none of the above? I just want to know how powerful her energy sensing would be.

She'd just feel uneasy around him at first, but might pick up on the undead thing after a while in the same party together. Having said that she's not prejudice in any way, the worst things that have happened in her life so far have been at the hands of regular humans and so she'd probably trust him more knowing he wasn't one of them.
