For the problem with the title...it would be easier to come up with something if we had a hint in what´s happening in the game.
Is there some mystical artifact involved? That would be good for some title in the style of "Quest for xxx", "Sword of xxx", Legend of xxx" etc.
Or maybe a special antagonist that would lend himself to the title? "Rise of (the bad guy)"

or so... If you battle demons it might work to put in something like the "Forces of the Netherworld" or so in the title
Or maybe a special locations name? Like a mythical land, or an empire or whatever.
These are just generic ideas from what JRPGs usually are called. Could also be something completely pointless, like Grandia. There was never anything called Grandia in the game.^^
Beside that, would it not make more sense to call it "Brave Battle Saga" instead of "Braver Battle Saga"? I mean, braver implies that it improves on something else in terms of bravery. But WHAT is it braver than? Would work for a sequel...with part 3 being called "Bravest Battle Saga"

Do the "Magical Warrior" and "Space Warrior" make any sense?
