How can I align Axis?

I was looking around, couldn't find an answer.. I am still very new to t$$anonymous$$s :P I am trying to change the axis of my character to that of the camera w$$anonymous$$ch is moved by a mouse, hence constantly changing axis, I would t$$anonymous$$nk.

Any how, I was wondering, how can I make my character axis constantly align with the camera axis? I have no script on t$$anonymous$$s so far, as I have no clue how to proceed.. Thanks in Advance :)
