Maki explains to Ruka that she was once the kunoichi's student. After revealing her death at the hands of Kirigakure, Ruka explains to Pakura that the "Bloody Mist" is no longer the murderous village it used to be thanks to the Fifth Mizukage, however Pakura does not think that it will erase the past. Pakura begins to attack the squad and incinerates the area to find the hiding shinobi. The squad protect themselves from the blast with Maki's Cloth Binding Technique and Ruka's Water Release. Pakura finds the squad and prepares to kill them until the arrival of Omoi and Zaji. As Gari's regeneration is finished, he joins Pakura in fighting the shinobi but having a change of heart, Pakura allows the squad to flee while holding Gari's movements.
