Miyamoto Musashi... a strange woman encountered in the minute Singularity. The concept of Pruning Theoretical Phenomenon... and a being who continuously warps from one world to another...

Too much remains a mystery about this woman. Historically, Miyamoto Musashi was a man who made his mark on the world as a master swordsman. What reason could there be for these two who share a name to be split as they are?

A new story unfolds after Musashi reappears and reunites with everyone at Chaldea. The time has come for the Seven Duels of Swordmasters to begin.

Note: This is the adaptation of the Epic of Remnant Chapter 3 from the mobile game, Fate/Grand Order.
