The story mode (or, in other words, the game's storyline) is fairly unique because it's storyline has some sort of long introduction, which is split in two, along with a final chapter (the prologue of the story) that finally introduces you to the game's main story, which is free for the player to explore to it's likings, the storyline parts are as follows:

Introduction
As stated earlier, the storyline's introduction is split in two:

Aria's Introduction: This part of the storyline's introduction features one/another of the main protagonists of the game, Aria, you must complete this part of the introduction to unlock the Prologue.

Isaac's Introduction: This part of the storyline's introduction features one/another of the main protagonists of the game, Isaac, you must complete this part of the introduction to unlock the Prologue.

Prologue: After completing both introductions, the Prologue of the story begins, featuring both Aria and Isaac in it, this chapter is not long, compared to the introductions. Beating the prologue allows you to proceed to the Main Story.

Main Storyline
Beating the whole Prologue unlocks the main story of the game, the special feature of this storyline is that you are in the newly introduced Dimensional Metropolis, it's relevance with the storyline is that it allows you to visit any unlocked dimension to go through the story it contains, you can also leave the dimension to enter another one and continue whenever you'd like. The dimensions are, in other words, the Chapters of the storyline, and they are split into:

Main Chapters: These chapters are dimensions that have major relevance to the storyline and you need to complete them in order to access the Final Chapter of the game, most dimensions have different gameplay, a storyline to offer and lots of content to be discovered by the player.

Secret Chapters: If you take your time to walk around the metropolis, you might end up discovering secret dimensions, these dimensions have no actual relevance with the main story, but you can access these as a form of additional in-game content to extend the gameplay and also let the player experience whole new worlds that await to be discovered.

Downloadable Content: Otherwise known as DLC, the content you download include patches, new content  and other things. At some point, there will be more extra chapters available to be downloaded, and who knows... maybe with every DLC chapter you download, there might also be more secret chapters to unlock.

Epilogue
Beating the Main Chapters allow you to access the final chapter of the game, this chapter is special since it reveals a lot of backstory for the protagonists as well as answering a lot of questions you could have while playing the game, regarding the protagonists of course. Completing the final chapter means that you will have completed the main story of the game. But even if that happens, you still got secret chapters to discover and DLC to purchase.
