The Starting Day
Tsuna wonders if his dad is even strong enough to combat him. Iemitsu challenges Tsuna to go into Hyper Dying Will Mode, and Tsuna hotly retorts that he could do it on his own, but that he was worried about his dad's well-being. Iemitsu brushes it off lightly, stating that he was worried about Tsuna, instead. Tsuna is angered and enters Hyper Dying Will Mode, with Natsu on his shoulders. Iemitsu smiles, commenting to Tsuna that he got stronger after the fight with Varia. Tsuna harshly states to Iemitsu that he was away from home all the time, and that he wouldn't know anything about him. Iemitsu states to Tsuna that being his son was enough, challenging him to come at him with all the resentment he's harbored. Tsuna reluctantly charges at Iemitsu and punches him hard with his X-Gloves, mentally resignedly commenting that he told Iemitsu so. Iemitsu, however, appears unfazed and comments that the punching brought back memories of Tsuna kicking him as a toddler, then sharply stating to Tsuna that he could put more into the punch.
Tsuna activates Natsu's Cambio Forma, punching Iemitsu even harder, but Iemitsu still remains unfazed and tells Tsuna to attack more vigorously. Iemitsu then tells Tsuna to pay attention, as what he was about to do was a real punch. Iemitsu then enters Hyper Dying Will Mode and punches Tsuna, sending him flying far away from the building. As the dust clears where Tsuna lands, Tsuna seems to be incapacitated. Iemitsu radios to the other CEDEF members that Tsuna was down.
At Enma's location, he suddenly recalls that his attackers were Varia, the said members watching Enma speak. Squalo roughly states that they should finish Enma off quickly, but Enma retaliates by trapping the members with Gravita della Terra. Skull applauds Enma's attack, but Enma realizes that the Varia members replaced themselves with their Box Weapons. Squalo then drops the sky, calling Enma an amateur, and to prepare himself.
Meanwhile, Gokudera, Yamamoto, and Ryohei to the site of the explosion to investigate, but they are interrupted by Hibari, with Fon sitting atop his head, accompanied by Hibird with Lichi sitting atop its head, and Hibari grimly states to Gokudera, Yamamoto, and Ryohei that he would bite them to death.
