Chapter Summaries

Ren met the Dog Sage, who revealed the Dog Clan’s origins and its near destruction by Madara Uchiha. The Dog Sage asked Ren to restore the clan and free its descendants from a bloodline seal, and Ren agreed to cultivate them.

• Ren entered Beast King Mountain and met the Dog Sage, who appeared with two unintelligent dogs.
• The Dog Sage explained that Madara Uchiha and the Nine-Tails had nearly wiped out the Dog Clan, sparing it only after the Sage traded away the secret of combining Asura and Indra’s power.
• The Dog Sage revealed that Asura had helped him awaken, taught him Sage Mode, and enabled him to found the Dog Clan using God Tree Fragments.
• The Dog Sage said Madara Uchiha had sealed the intelligence of the clan’s descendants with a Genjutsu passed down through their bloodline, and that he could not remove it himself.
• The Dog Sage asked Ren to help the dogs grow and restore the clan, and Ren agreed to cultivate them.

Ren learned of the Dog Sage’s loyalty to Indra and accepted responsibility for the Dog Clan, then discovered the clan’s vast library and the seal keeping its members’ intelligence and Chakra dormant. He began studying the Dog Sage’s research into how the seal worked.

• The Dog Sage told Ren that Asura had helped establish the Dog Clan, but he remained loyal to Indra and entrusted the clan’s future to Ren before passing away.

• Ren surveyed the Dog Clan’s more than ten thousand dogs and followed a Tibetan Mastiff to a cave containing books on Sage Mode, sealing techniques, and ninja dogs.
• The Ghost-Faced Mastiff King showed Ren the Dog Sage’s notes, which explained that the seal trapped the dogs’ spiritual power in their cells and prevented them from producing Chakra.

Ren learned that the Ghost-Faced Mastiff King’s loss of intelligence came from a Spirit-Sealing Technique and dumped the Trash Station’s accumulated garbage onto Beast King Mountain. The next day, Mikoto identified the seal and offered to bring Ren the Uchiha scroll, but a group of youths approached the classroom, apparently targeting her.

• Ren discovered that the Dog Sage’s Natural Chakra body-strengthening method could help the Dog Clan resist the seal, though overuse risked beastification.

• Mikoto recognized the seal as the Spirit-Sealing Technique and promised to bring Ren the scroll from her family’s collection.
• A group of youths approached Ren’s classroom, and Kushina said they had come for Mikoto.

Ren’s eyes awakened as the Mangekyō Sharingan during a confrontation between Fugaku Uchiha and Nawaki at the Ninja Academy. He fled to Beast King Mountain and discovered that his deceased father had sealed three ocular techniques inside his eyes.

• Fugaku Uchiha visited Mikoto, and he and Ren immediately felt hostility toward each other.
• Nawaki confronted Fugaku in the classroom, and the two challenged each other to fight outside.

• Ren left for the empty dance studio, summoned himself to Beast King Mountain, and saw his Mangekyō Sharingan reflected in a crystal.
• Ren realized his deceased father had sealed three ocular techniques inside his eyes.

Ren discovered that the three eye techniques sealed in his eyes could be controlled and used as powerful attacks, then returned to class and learned Nawaki had fought Fugaku. Meanwhile, Tsunade, Jiraiya, and Orochimaru were trapped and badly injured in the Land of Earth, and Tsunade swallowed Ren’s Qilin Resin in a last attempt to survive.

• Ren learned that his father’s sealed eye technique had nearly activated against Fugaku and gained control of the three techniques, which he could use three times.
• Ren returned from Beast King Mountain and found Mikoto and Kushina waiting for him before joining the outdoor class.
• Nawaki told Ren that he had beaten Fugaku, while Ren warned him that Tsunade would be angry if she found out.

• Jiraiya urged Tsunade to use Ren’s Qilin Resin, and she swallowed it, hoping it would save her.

Tsunade recovered after taking Ren’s medicine and unleashed her Senju vitality against the Earth ninjas, while Jiraiya sent intelligence away.

• Ren practiced chakra control, tried combining water-walking with the Fireball Jutsu, and then performed a summoning in his bedroom.

Ren discovered that the Dog Clan had broken free of its seal and grown to enormous size after a mysterious energy from his discarded trash transformed them. He suspected the RR Virus from the Swallowed Star world had caused their evolution, but the trash and the corpse that emitted the energy had vanished.

• Ren stored his monster egg and Foundation-Building Spirit Liquid in the Dog Clan Hall, then found the Ghost-Faced Mastiff King and seven other dogs had grown enormous and broken free of their seal.
• The Husky told Ren that mysterious energy from the trash he had dumped the previous day had transformed the Dog Clan.
• Ren rode the Ghost-Faced Mastiff King to the dumping site and found that the trash and a decomposing human corpse had disappeared, leaving steel, a Lamborghini, grass, and saplings.
• The Ghost-Faced Mastiff King explained that the corpse had emitted the energy that caused its evolution, while the Husky confirmed that the seal had spared the Dog Clan from deaths during the transformation.
• Ren concluded that the RR Virus from the Swallowed Star trash had caused the Dog Clan's evolution and wondered why the rest of the trash had vanished.

Ren learned that Beast King Mountain could devour energy and might become a Natural Chakra-gathering Holy Land, while the evolved Dog Clan prepared to develop further. The next day, Ren received an old sealing scroll from Mikoto and Kushina Uzumaki, but Nawaki rushed him away with shocking news from his sister.

• The sled dog told Ren that the Dog Sage had placed a crystal in Beast King Mountain to let it devour energy and eventually refine Natural Chakra.

• Nawaki rushed into the classroom, grabbed Ren, and said his sister had sent shocking news before taking him away.

Katsuyu reported that Tsunade had used the Qilin Resin to defeat hundreds of Rock Ninja and badly wound Ōnoki, and warned that Nawaki was now a target for assassination. Rock Ninja ambushed Nawaki and Ren at a deserted training ground, leaving them to face three attackers.

• Nawaki summoned Katsuyu, who told Ren that Tsunade had killed two hundred Chunin and nine Jonin, wounded Ōnoki at the cost of an arm, and recovered the next day.
• Katsuyu warned that Ōnoki had ordered Nawaki's assassination because of his inherited Senju constitution, but said the Rock Ninja did not know about Ren's connection to Tsunade.
• Ren sensed killing intent and warned Nawaki just before a Kunai flew toward him, allowing Nawaki to dodge it.
• Three Rock Ninja emerged from the forest, and Katsuyu charged at them while telling Ren and Nawaki to flee.
• The Rock Ninja explained that they had been watching Nawaki and Ren, then one charged at Ren as the two boys faced the ambush.

Ren used his sensory ability and an unusually sharp katana to kill a Rock Ninja, but an Iwagakure Jonin ambushed and wounded him. The Jonin approached Ren while the other Rock Ninja watched, leaving Ren facing a powerful enemy inside Konoha.

• Ren sensed an underground threat as a Pangolin stopped Katsuyu, while Nawaki held off two Rock Ninja without using ninjutsu.
• A Rock Ninja wounded Ren with a Kunai, and Ren drew his katana and killed him with a slash.
• Ren steadied himself after killing the Genin, and Nawaki urged him to escape and find help.
• An Iwagakure Jonin appeared with the Body Flicker Technique, struck Ren in the abdomen, and walked toward him.

Ren used a Mangekyō Sharingan technique to kill an Iwagakure jonin and two Genin who attacked him and Nawaki, then woke at home after his grandfather concealed the battle. As Ren recovered, he recognized how limited his remaining ocular technique uses were and resolved to become stronger.

• The Iwagakure jonin crushed Katsuyu, knocked Nawaki unconscious, and advanced on Ren, who swallowed Qilin Resin to recover.
• Ren activated the ocular technique sealed in his eyes, burning the jonin and two Genin to ash before collapsing from the pain.
• Ren's grandfather explained that Konoha's clans were searching for spies and said his people had removed the battle traces and erased Nawaki's memories of the jonin.
• Ren learned that Qilin Resin had healed his injuries, then ate lunch with Kushina Uzumaki and Mikoto.
• After Kushina Uzumaki and Mikoto left, Ren reflected that only two uses of his ocular technique remained and wished for treasures that could increase his strength.

Ren explored a new Trash Station dump and discovered it came from Perfect World, including an ancient medicinal cauldron from Bèi Village. After identifying the dump’s origin and uncovering its history, he left excited by the cauldron’s potential.

• Ren entered the Trash Station and found an enormous new pile of dirt, stones, and wood.

• Ren uncovered a beast hide describing the last survivor of Bèi Village, who had given up revenge against Willow Village and Shi Hao.
• Ren concluded the cauldron had been Bèi Village’s medicinal cauldron and considered it a valuable tool for strengthening physiques.

Ren brought a medicine cauldron, a Fire Tiger carcass, soil, and a white bone from Bèi Village in Perfect World to Beast King Mountain. The dogs sensed powerful energy in the soil and bone, and Ren left the bone for them to share.

• Ren found that the medicine cauldron had absorbed medicinal properties, but it was too heavy for him to move, and he decided to leave it on Beast King Mountain.
• Ren summoned the Ghost-Faced Mastiff King and the other dogs, then used the Trash Station to dump the dirt, medicine cauldron, Fire Tiger carcass, and white bone onto their dumping ground.
• The sled dog sensed that the dirt held dense Natural Energy of a quality beyond Natural Chakra, and Ren realized even soil from powerful worlds could be valuable.
• The dogs yearned for the white bone, and the Ghost-Faced Mastiff King and sled dog said eating it might help them grow stronger.
• Ren told the dogs to keep the bone and decide among themselves who would eat it.

Ren organized the Dog Clan to salvage Fire Tiger’s remains and prepare a medicinal bath, then used a drop of Foundation-Building Spirit Liquid to strengthen it. The bath turned green, and Ren was left ready to use it to improve his strength.

• Ren ordered the Dog Clan to move the medicine cauldron and Fire Tiger’s corpse into the hall while Papillons searched the dirt for valuables.
• Ren had Fire Tiger’s whip sealed for him to soak in liquor, then watched the dogs prepare a medicinal bath using herbs and the medicine cauldron.
• The sled dog explained the Dog Clan’s lost divisions and revealed that its thirteen thousand six hundred members had given Ren the tiger whip in hopes he would establish a family line.
• Ren promised to restore the Dog Clan’s functions and decided to risk using Foundation-Building Spirit Liquid to grow stronger after facing assassination attempts.
• Ren added one drop of Foundation-Building Spirit Liquid to the medicinal bath, turning it from pale red to green.

Ren endured a painful medicinal bath that strengthened his body and increased his Chakra tenfold, until a mysterious egg absorbed the bath’s remaining power and hatched into a small white dog. Ren left the Dog Clan with Chakra comparable to Kushina Uzumaki’s at the same age.

• Sheepdog identified the unfamiliar herbs in Ren’s medicinal bath, and Ren entered the cauldron to cultivate.
• The medicinal power overwhelmed Ren, and his Chakra blocked Sheepdog from pulling him out.
• Ren’s white egg dropped into the bath and absorbed the medicinal power, sparing Ren and cracking open.
• A little white dog emerged from the egg, and Ren asked Sheepdog what breed it was.
• Ren discovered that his physique had strengthened and his Chakra reserves had increased tenfold, reaching a level comparable to Kushina Uzumaki’s at the same age.

Ren increased his chakra, helped the Dog Clan rebuild, and returned to Konoha, where Nawaki brought him to meet Tsunade, Orochimaru, Jiraiya, and Kushina. Tsunade thanked Ren for helping her and Nawaki.

• The Sled Dog offered to raise an Eight-Headed Hound to fight alongside Ren, while the Sheepdog cared for the mysterious puppy hatched from an egg.
• Ren learned that the dogs had found Bèi Village stone utensils, unknown seeds, and a broken piece of lingzhi, and he ordered supplies sent to the Dog Clan.

• Ren spent several days sending supplies to the Dog Clan, which used them to rebuild its trades and training system.
• Nawaki took Ren to Konoha Training Ground One, where Ren found Tsunade, Orochimaru, Jiraiya, and Kushina waiting.
• Tsunade thanked Ren for helping her and Nawaki.

Ren received Tsunade’s thanks for saving her and Nawaki, then accepted her taijutsu scroll as a gift. He left with a fighting style suited to his strong physique and a debt of gratitude between them.

• Tsunade denied taking the Qilin Resin, kissed Ren on the cheek, and thanked him for saving her and Nawaki.
• Nawaki questioned Tsunade’s gentleness, and she threatened him with a punch before he took it back.
• At Training Ground One, Orochimaru praised Ren’s physique while Jiraiya proudly called him his disciple.
• Tsunade gave Ren a scroll containing her taijutsu, including Chakra Enhanced Strength, and explained its lineage and battlefield adaptations.
• Jiraiya told Ren that Tsunade had developed the taijutsu through repeated explosive bursts after taking the medicinal herb, so Ren deserved some credit.

Ren mastered the Rasengan and worked out the Trash Station’s rules, realizing that only a major improvement to his body, spiritual power, or Chakra would trigger better garbage. He examined a new haul from the Bright Sword world and found mostly firearms and corpses, leaving him to focus on strengthening his physique.

• Ren mastered the Rasengan after several months of training and reflected on the escalating Second Shinobi World War.
• Ren concluded that the Trash Station produced garbage when his strength improved significantly or at fixed intervals, with stronger growth yielding garbage from stronger worlds.
• Ren decided to focus on improving his physique because he could not safely increase his Chakra and his spiritual power grew too slowly.
• Ren examined a haul from the Bright Sword world, identifying guns and cannons from the Yamamoto Squad’s raid, including a pistol associated with Chu Yunfei and Li Yunlong.

• Ren found the Going Merry and many fish in a new Trash Station delivery and planned to have Papillon search the ship.
• A maid told Ren that Kushina had arrived in tears, so he took her to his sealed bedroom and ordered the maids to keep the news secret.
• Kushina told Ren that Mito was dying and begged him to save her, but Ren said her lifespan could not be restored.
• Kushina said Mito had considered her physique more suitable for becoming a Jinchuriki while Reiko had more advanced Sealing Jutsu, and Ren urged Kushina not to accept the role.

Ren accompanied Kushina to see Mito Uzumaki as her health faltered and the village faced the choice of who would become the Nine-Tails’ jinchuriki. Tsunade arrived and brought Ren into the room where Mito and Konoha’s leaders had gathered, leaving the decision unresolved.

• Nawaki came to take Kushina back and told Ren that Mito wanted to meet him, hoping Kushina would have someone who would not reject her if she became a jinchuriki.
• Nawaki said that after Mito’s death, the choice would be between Kushina and Reiko, and admitted he wished he could become the jinchuriki himself.
• Tsunade appeared and tested Ren with a punch, then praised his taijutsu and Medical Ninjutsu while scolding Nawaki for avoiding training.
