A reminder before you read: this book is also known as "The Clock Tower's Foolproof Demise Plan," "Fujimaru Ritsuka's Revenge," and "Humanity's Incineration: The Sequel."
[Some say the bonus chapters are even better than the main story. "Covers face"]

Ritsuka: Mom Emiya, I want a full Manchu-Han banquet.
Emiya: Who's your mom? And you're supposed to be here helping me!!!
