The FGO derivative novel tells the story of Ritsuka Fujimaru who saves humanity in the same timeline but in different time and space.
Fujimaru Ritsuka is just an ordinary girl, but in the end she has to do something to save humanity.
Romani Achiman is just an [ordinary] human being, but no one thought that he was...
For Romani, Ritsuka Fujimaru is not only a master, but she is also the person in his heart.
For Fujimaru Ritsuka, Romani is not only a Chaldean doctor, but also the person who can make her give up everything.
For them, [saving humanity] is the most important thing.
But they didn't expect the final result.
Intention: I hope everyone can identify the things they have done in their hearts and not regret it
