Another plot could involve a crossover of the two worlds' educational systems. The students from Ansatsu Kyoushitsu might attend classes in the Touhou world, learning magic instead of assassination. 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.
