Fujimaru Ritsuka Is Fighting Their Way Out of the Lostbelt

Miss Fujimaru Ritsuka, humanity's last savior, has just defeated Chaldeas. She hasn't even had time to begin her university life. Just as she's about to cross the boundary and return to Pan-Human History, she blinks and finds herself back in Chaldea in 2015.

What does this mean? I haven't even clocked out, and you're dragging me back to work?

But no matter. This time, I'm on my second run. Watch me become Information Ritsuka and tear through every Singularity and Lostbelt.

Wait, what do you mean this Chaldea is like a haunted house, with nobody here? What do you mean the Earth has already been bleached, even though it's 2015? And what do you mean there are seven Lostbelts, but they're completely different from the ones I knew, so the old conquest guides are useless?

Hold on, this isn't a second run at all! Where am I?!

P.S. I was so exhausted after watching FGO's final chapter that I angrily decided to write a new Part Two story myself. This is essentially a tenth-anniversary work, featuring seven brand-new Lostbelts. Since it takes place after the real Part Two ends, it should more accurately be called Part 2.5, or an interlude.
