There's a good amount of stuff on here. I already beat the game but there's some parallel quests that I haven't beat/would like to do better in and there's 2 secret sagas after you beat the game. Parallel quest are set characters at set stages that you have to VS to unlock skills, costumes, transformations, combos, etc.. Ranking 1 - 7 star difficulty. You should really take a look at some of the game explanations on youtube to see what I mean. Good luck with your decision.
