Black Cat, Katekyo Hitman Reborn! Recommendations
Black Cat and Katekyo Hitman Reborn have the same feel when it comes to the shounen fights. Plus, their humor is the same too! While the beginning of Reborn has a different buildup (In Black Cat, the action starts right away), when the action in Reborn begins, it is just as good.
Anyone who likes Black Cat will like Reborn, and vice versa~
