Closed Path is the 150th episode of the Katekyo Hitman Reborn! anime.
While Tsuna's family is recuperating, Verde completes the first stage for his Box Weapons and decides to seek out the Vongola Rings to help him complete the second stage. All of the Arcobaleno, except Verde, gather at Namimori Shrine to discuss about the trials. Tsuna, Gokudera, Yamamoto, and Ryohei discuss about their battle with Reborn and how they lacked resolve in the trial which caused their defeat. At that moment, Verde sends his inventions to attack the Vongola Ring holders. Reborn announces to Colonnello and Lal Mirch that Verde has broken the Arcobaleno pact and must be stopped.
