Reborn explains that Xanxus' X-Guns were modeled after the gun that Vongola Settimo used, which absorbed the user's Dying Will Flames and compressed it into a bullet. Tsuna charges and attempts to punch Xanxus, but the latter propels himself away by firing the X-Guns' bullets, causing Reborn to comment that Xanxus was quite powerful, combining the Vongola Secondo and Vongola Settimo's techniques and weapons. Xanxus taunts Tsuna about his statement that he wouldn't let his Guardians die, and the former fires his X-Guns, knocking down his Storm and Lightning Guardians' poles and injecting them with the antidote. Belphegor and Levi A Than go loose, searching for and trying to kill the other side's Guardians, but Hibari intercepts Belphegor.
The Cervello express their awe and shock that Hibari managed to free himself, the poison being able to stop even an elephant in its tracks. Meanwhile, Levi A Than is about to attack Lambo, but Gokudera intercepts him as well. Xanxus scoffs, calling Tsuna's Storm and Lightning Guardians scumbags, but Tsuna ignites his X-Gloves with Sky Flames, telling Xanxus to concentrate on his battle with him.
