The Millefiore are fighting the Titans, so when Raven finds some backup in five of the Vongola members it's gotta be a good thing. However, it's not the best thing because body swaps ensue. Has no characters who appear after the Choice arc of KHR or the first season of Teen Titans. No ships unless you squint.

When a mysterious thief by the name Red X shows up and starts stealing from the Vongola, it's up to Tsuna and his friends to stop him. At the same time however, they find themselves asking: Who is Red X? A Teen Titans and Katekyo Hitman Reborn crossover.
