In Konohagakure, Tsunade states that Naruto is wanted for attempting to assassinate the leader of Kumogakure, the Raikage, and killing jōnin from Kumogakure and Iwagakure, showing wanted posters of Naruto from Iwagakure and Kirigakure to Team Kakashi. Naruto and Sakura refuse claims, but Tsunade states Naruto will be placed in the Hōzuki Castle, a criminal containment facility, also known as the "Blood Prison", in Kusagakure. Naruto attempts to escape, only for Yamato to encase him, and Tsunade takes away his forehead protector. When Naruto arrives at the Hōzuki Castle, Mui, the head of the prison, quickly places the Fire Release: Heavenly Prison on Naruto, sealing his chakra. Naruto learns this the hard way after using his shadow clones, Naruto quickly collapses from the pain caused by the seal. Naruto is later taken captive by Maroi who is working for Mui, when Naruto is brought to a lab, Mui realises that the Naruto taken was a clone. While the real Naruto was hiding, he used the chance to escape. But the pain from the seal made him pass out, he was taken into solitary confinement. When in solitary confinement, he hears a mysterious voice say, if he can defeat Mui, then the seal will disappear. Naruto then after being released, attacks Mui. But the seal causes Naruto to collapse, and he is taken back into solitary confinement. During the fight, Mui questions Naruto's devotion to his home, wondering why he bothered being loyal.
