• Duke used the Eight Trigrams One Hundred Twenty-Eight Palms to incapacitate Ao, leaving him badly injured but alive.

Duke and Terumi Mei reviewed their plans to assassinate Yagura, and Duke decided to infiltrate the Mizukage Building that night to investigate who controlled him. Elsewhere, Zabuza joined a group of Mist Shinobi whose elders-backed assassination plan was also set for that night.

• Duke inspected Terumi Mei's information on Yagura and argued that his daily associates and whereabouts mattered more than his listed habits and preferences.

• Zabuza realized the elders were using the group as pawns but decided to take the opportunity to kill Yagura.
• The group finalized its assassination plan for that night and pledged to act for their clans and Kirigakure.

Duke and Terumi Mei infiltrated the Mizukage Building as Zabuza led a rebellion against Yagura. While Zabuza fought the Fourth Mizukage, Duke slipped into the office and came face-to-face with a masked Anbu he suspected was Obito.

• Terumi Mei worried that the Mizukage Building's lax security was suspicious, but agreed to cover Duke while he investigated inside.
• Zabuza and the rebel Mist Shinobi defeated the Anbu guarding the plaza, then faced Yagura and his forces.
• Yagura unleashed the Three-Tails' chakra to flood the plaza, and Zabuza fought him in close combat.
• Zabuza tricked Yagura with a feigned opening and struck him hard enough to send him flying.
• Duke avoided the battle, searched the Mizukage's office, and found a masked Kirigakure Anbu at the doorway.
• Duke instinctively asked the masked Anbu if he was Obito.

Duke confronted Obito in the Mizukage’s office and tried to break Madara’s hold over him by showing him photographs of Rin. Obito rejected the memories and attacked Duke, leaving them poised for a fierce battle.

• Duke and Obito exchanged attacks, with Obito using Kamui to evade Duke’s blows and Duke charging through Obito’s Great Fireball with an Ice Release Rasengan.

Duke fought Obito while Yagura and Zabuza clashed below, then summoned the Blue-Ice White Night Dragon to battle Yagura’s Three-Tails. As the fight wrecked Kirigakure’s center, Terumi Mei arrived and asked whether Obito was controlling the Mizukage, leaving Duke worried she might recognize him later.

• Duke and Obito exchanged attacks around the Mizukage Building, but Obito’s phasing kept Duke from landing a hit.

• Terumi Mei reappeared behind Duke and asked if Obito was controlling the Mizukage, while Duke worried that she might learn Obito’s identity.

Duke and Terumi Mei fought Obito as he tried to destroy Kirigakure and take control of the Three-Tails. After breaking through Obito’s barrier, Duke and his Ice Clones unleashed a massive barrage against him, leaving his fate unclear.

• Terumi Mei said her family could gather about ten million Explosive Tags, far short of Duke’s hoped-for six hundred billion.

• Duke tricked Obito with a Shadow Clone, marked him with a Flying Thunder God coordinate, and left Terumi Mei and his Ice Clones to deal with Yagura and the Three-Tails.
• Duke used his delayed Flying Thunder God technique to reach Obito outside Kirigakure and took Madara’s Sharingan from him.

Duke returned to Konoha with Haku and Jingzi after saying goodbye to Terumi Mei, who gave him his Missing-nin forehead protector and secured a space-time coordinate from him.

• Duke saw Sarutobi farewell Ay after Kumogakure had ransomed Killer B, and Killer B spotted Jingzi in the crowd.

Duke secured Konoha citizenship for Jingzi and Haku, reported Kirigakure’s turmoil to Hiruzen Sarutobi, and received two S-rank mission rewards. In the Unknown Space, a Duke from the One-Punch Man World appeared and explained that his training had not made him bald or exceptionally strong.

• The Fourth Raikage glared at Duke over Killer B’s capture, but turned away after scolding Killer B while Duke led Jingzi and Haku into the Hokage Building.

• A newcomer from the One-Punch Man World accidentally merged memories with the Dukes in the Unknown Space and introduced himself as a C-Class Hero.
• The One-Punch Man Duke explained that three years of Saitama-inspired training had left him healthy and strong-haired, but otherwise ordinary and worried about losing his Hero Association rank.

Duke attended a Male Soul Reapers Association meeting where dwindling membership and funding left the group close to collapse. A Seireitei alarm announcing intruders interrupted the meeting, and Duke recognized the Ryoka invasion as the start of the plot.

• President Iba told the Male Soul Reapers Association that members were resigning and its funding would run out in three months.
• Ukitake proposed increasing publicity and benefits, while Iba explained that funding had been diverted to the Female Soul Reapers Association.

• An emergency alarm announced that intruders had entered Seireitei, and the Soul Reapers rushed to prepare for battle.
• Duke escorted Ukitake to the 13th Division and identified the intruders as the Ryoka, connecting their arrival to the Soul Reaper powers given to a human by Kuchiki Byakuya's sister-in-law.

As Ryoka battles spread through the Seireitei, Squad 4 vice-captain Duke intervened when Squad 11 members threatened Hanataro, then faced Chad while Ichigo and Ganju fled. Ichigo later encountered Kenpachi Zaraki, who warned him that Duke was extraordinarily strong before challenging him to a fight.

• Hanataro stumbled into Ichigo and Ganju’s battle with Squad 11, and they took him hostage while trying to escape.
• Squad 11 fighters dismissed Hanataro’s safety, but Duke arrived and reprimanded them for threatening a Squad 4 member.

• Duke approached Chad, who declared he would defeat him within one minute.
• Ichigo and Ganju rested elsewhere, where Hanataro warned them that Duke was extremely strong.
• Kenpachi Zaraki appeared before Ichigo, confirmed Duke’s strength, and challenged Ichigo to fight.

Ichigo confronted Kenpachi while trying to protect his companions, but Kenpachi overwhelmed him and left him gravely wounded. As Ichigo chose to keep fighting rather than simply survive, Duke sensed that his Reiatsu had not vanished and that a turning point was near.

• Ichigo sent Ganju and Hanataro ahead to find a way to save Rukia, while Kenpachi agreed to let them go if Ichigo gave him an entertaining fight.

• Duke revealed that Chad was alive and being taken to prison, then stepped aside so Kenpachi could fight Ichigo.
• Kenpachi easily crushed Ichigo, whose attacks could not injure him, and left Ichigo badly wounded after cutting Zangetsu in half.
• As darkness overtook him, Ichigo told Old Man Zangetsu that he wanted to fight, while Duke sensed that Ichigo's Reiatsu had stopped just short of disappearing.

Ichigo recovered through his cheat and defeated Kenpachi, but Duke’s Zanpakuto healed Kenpachi after Duke stabbed him. As Duke and Kenpachi argued over Ichigo’s fate, Yoruichi Shihōin snatched Ichigo and fled, leaving Duke blocked by Kenpachi.

After Captain Aizen Sōsuke’s death, the Captain Commander tried to convene a meeting, but Duke, Kenpachi, and Retsu Unohana fought instead. He sent Tōshirō and Shunsui Kyōraku to stop them, then personally set out as the three continued their battle.

• Duke, Kenpachi, and Retsu Unohana fought fiercely, trading sword techniques as their battle devastated the surrounding area.

Duke defeated Kenpachi in a fierce sword battle, leaving Kenpachi devastated that he could not become stronger or learn his Zanpakuto’s name. Duke then fought Unohana, who revealed she had not stopped training and continued attacking him.

• Retsu Unohana activated Minazuki and fought Duke in a sea of blood, restoring herself and raising her reiatsu.
• The Captain Commander, Shunsui Kyōraku, and Tōshirō arrived as Kenpachi’s reiatsu surged and he released Nozarashi.
• Kenpachi asked whether anyone had seen Yachiru, then challenged the Captain Commander, who drew Ryūjin Jakka and fought him.

The Captain Commander ordered the fighters back to their squads to await Central 46’s judgment and sent Kenpachi Zaraki to Squad 4 without allowing Duke to heal him directly.
