Demon Spade doesn't budge on his stance on the ideal Guardians. He decides to battle Tsuna, to beat him into submission. The two start to battle with Tsuna able to fight Demon on equal grounds; however, Demon targets the girls, turning the tides of battle in his favor. Demon states his devotion to the Vongola, going on to say that he was the Mist Guardian for two generations. Tsuna gains the initive in the battle, and prepares to fire his X-Burner, Demon however, uses his illusion to make Tsuna lose track of where Demon really is. Demon tricks Tsuna into firing his X-Burner, and to Tsuna's horror, it was aimed at the girls. Mukuro Rokudo finally arrives and saves the girls from the attack, much to the surprise of Demon.Mukuro lets Tsuna handle the battle, and even assists Tsuna by nullifying Demon Spade's illusions. Demon disappears after getting hit by the X-Burner, but as he never had a physical body, he's able to reappear. He and Mukuro have a discussion on their goals and ideals. Demon takes a liking to Mukuro and even states that he wouldn't mind giving his inheritance to Mukuro. Mukuro, however states that he has no interest in the inheritance, asks Tsuna to look after Chrome Dokuro, and disappears.
Giotto appears and thanks Demon for fulfilling his duty as the Guardian of the Mist. After a short discussion between the two, Demon gives his inheritance to Chrome and leaves.
Tsuna, nervously asks Giotto, about his own inheritance, to which Giotto replies that Tsuna has already impressed him, and already passed the test. He too, then gives his inheritance and leaves.
Elsewhere Giotto meets Demon once again, and talks about the old days. Giotto stated that he haven't change his feelings which Demon commented him to be a forever fool and that's why Giotto disappointed him in the end and back to the Vongola Rings.
Back at their homes, everyone makes the necessary preparations to go back to the future. The girls refuse to stay back, and insist on going back with them to help. The next day, they all gather at Namimori Shrine and go back to the future, and prepare themselves, for the battle that lies ahead.
