So...
In chapter 1, Waver is sitting with the Night Round painting behind him.
And in chapter 3, we have The Lord Supper during the breakfast is in the background.
Take as much time as you need for each chapter man, I love getting to read shit delving into nasuverse things outside FGO's heroic spirits. Just wish type moon would release their stuff internationally!
It's frustrating every time to see something cool and go "oh, it's a part of the franchise", especially if it's multimedia. Though I hope at least nasuverse fans are happy.
