This sounds like something I would be interested in. This premise sounds closer to Digimon than anything with the virtual setting and the single partner for each character while the structure seems like a JRPG with the quest to defeat six bosses; maybe a JRPG is what the game appears to be from the outside?

I like the idea of each creature fitting a certain theme, but I would question why bravery is included in that list. With the other five themes you have almost matched the classic DnD character stats of strength, intelligence, agility (dexterity), defense (constitution) and charisma, but you have bravery instead of wisdom. If the similarity to RPG stats wasn't your intention then I'd still say that bravely seems oddly out of place alongside the others.
