Well, the big question is:  how did Ryouga piss him off?  If it's
just a trivial thing the guy won't stay around forever to beat up Ryouga.
He either must have a major reason for revenge, or finds something in
Nermia that interests him.....maybe Ryouga's new innazuke would
work....<grin>

	Hmm, you've described him as a hunter, right?  Well suppose that he is 
the heir of an ancient order of hunters or something like that, and as a final 
test they have to track down a rnadom person.  If that Random person was Ryouga 
then Ryouga's directionlesness would make him really hard to track, which could 
be responsible for making the hunter take longer than the proscribed time period 
to find Ryouga.  This would represent an extreme personal disgrace to blame 
Ryouga for.
