"Start Journey" is basically the campaign mode of the game where you get to play the 18 different chapters that takes you to the very story of the game. Every chapter, there will be multiple levels which houses different NPCs that you'll be racked up against with. Of course, given the fact that you are currently roaming around a
world run by fashion, each step of the way is a fashion battle -- which means you are supposed to battle with each character you meet along your way -- might that be for sports wear, festival wear, school wear, and what not.
Different Modes (Maiden and Princess Mode)
If you are playing the first time and you're on your first few hours in the game, you wont be able to notice the different modes of the game -- at least until you've completed a chapter in the game as the princess mode of a pertaining chapter wont be available until you've completed the maiden mode. What the princess mode really is - is a harder mode of the similar chapter. What it has in store for you are better rewards upon completing them.
Additionally, you should take note that the Princess mode consumes more stamina (6 per trial compared to that of just 4 stamina on maiden mode). Each level can be engaged a maximum of 3 attempts (either to beat it or similarly if you are just trying to earn an "S" rating). Any additional attempt would generally set you back 30 diamonds -- so take your time to plan Nikki's outfit well. What's good about the princess mode too is that the items you'll be able to earn from here (battle rewards) can be used for crafting in the Recipe Workshop -- meaning they can be evolved into something unique (and better to boot) to add to your wardrobe.
Side Quests
Apart form the main sequence of levels branching out one after the other, you'll sometimes see over-arching levels in a chapter that do not necessarily need to be played in order to progress in the concluding chapters of the game. However, these side quests usually endow you with unique items as rewards -- that are just too good to miss most of the time. So we highly advise to take the time to play these levels anyway!
