I don't believe there was ever a crossover between these two series, and I found that to be a complete surprise. This is what would happen if Toradora! and Boku Wa Tomodachi Ga Sukunai were crossed over, taking place in St. Chronica's Academy. T for mild language, may be boosted later to M later on.
