Tsuna and his friends are told that they did not pass Reborn’s test. If they don’t collect all seven seals of the Arcobaleno, they can’t open the Vongola box. Without the Vongola box, they would lose all means of fighting Byakuran. Will they be given a second chance? Or has the future been closed off to them? Tsuna and his friends are upset, but they somehow muster up the energy to ask Reborn for a second shot. Reborn goes silent upon being asked. But just then, weapons fire and explosives detonate. The last Arcobaleno, Verde appears!
@narutodude488 nice idea, but remember, the Arcobalenos have been babies since shortly after Aria was born and she's already an adult. Besides, can'r imagine Hibari being even part Chinese. His Japanese pride is too ingrained.
