And vice versa, some Touhou characters could come to the school to learn about modern - day combat skills and strategies.
A crossover with a post - apocalyptic world would also be interesting. The students would have to adapt their assassination techniques to survive in a world full of ruins, scarce resources, and new threats like mutated creatures or gangs. They would need to find a balance between their original mission and the new challenges of survival.
Well, Nagisa's ability to turn invisible could be used in the Touhou world for some sneaky spying.
