it isn't in the strategy guide so don't bother to look. i know cause i have it. This is what it says in the guide:
Dante is the 1/2 human, 1/2 demon son of sparda, the legandary demon swordsman who forsook his evil powers to seal the doorway between the demon world and the human world. Dante wields the twin semi automatic pistols Ebony and Ivory along with the symbolic sword Rebellion, given to him as a gift from his father years ago. Greatly skilled at the use of these weapons, Dante has recently decided to use his half demon powers to start a devil hunting bussiness.
However i did find his weight and weight in a website profile. but it's from a role playing site and its their thoughts on that... but i think it seems accurate. you decide?...
