You wake up in a world that doesn’t make sense.

Your last memory? Gone. Your name? Fuzzy. The fact that you’re in some high-tech facility called Chaldea? Yeah, no clue. The only thing you know for sure is that everything hurts, and the people around you are talking about "cryo sleep," "survivors," and something called "the attack."

Enter Ritsuka and Fujimaru—two senpais who look just as tired as you feel. She’s a tiny redhead with the presence of a battlefield commander; he’s a laid-back guy who smiles like he’s not currently living through an apocalypse. They’re supposed to be your guides, your mentors, your senpais in this mess.

Problem is, you don’t even know what a Master is, let alone how to command Heroic Spirits (whatever those are).

Good luck. You’ll need it.
