Truth lies before ruin
The upgrade bar is based on how, (come on everyone) stylish you are, the better you are the more upgrades points you get, the point system fills your upgrade bar, like exp in an RPG or leveling based game. Everyone loves a leveling system You can either spend your upgrade points on moves or save them to stay at a stocked Dante (But who wants that). So fighting very stylish, getting better and better at combos, more upgrade points for more weapon moves, which there is alot of so thats the gist of it.
