Ch. 127Natsu's Helplessness: Why Hasn't My Mangekyo Sharingan Awakened Yet?!

Natsu could not awaken his Mangekyo Sharingan, sensing instead that a deeper power within Indra's Eye was still developing. On Origin Island, Fugaku received a scientist rescued by Natsu and learned that the man was willing to work for anyone who let him continue his research.

  • Natsu found that his ocular power exceeded ordinary Mangekyo Sharingan levels, but its awakening remained blocked as an unfamiliar power gestated beyond the bottleneck.
  • Natsu considered that he lacked the intense emotional turmoil that usually triggered the Sharingan's evolution and decided to wait for his eyes to awaken naturally.
  • Fugaku read a report that Marine branches across West Blue had withdrawn, though he recognized the retreat as a temporary pause rather than a victory.
  • Natsu's Shadow Clone brought Drake Vallen to Origin Island and told Fugaku that the scientist's genetic engineering expertise could benefit the Uchiha.

  • Fugaku assigned Kei, Tetsuka, and Yashiro to seize Rukan, Balin, and Seraya, instructing them to avoid making noise if Genjutsu could resolve matters.

Uchiha Natsu completed the initial stage of the Void Demon Fox’s senjutsu and considered how its slow, continuous cultivation could transform the Uchiha Clan. Before returning, he established rules for marriages between Uchiha and outsiders, then departed using Flying Thunder God.

  • Uchiha Natsu sensed that his Sage Mode had taken its initial form and could now activate it at will.
  • Uchiha Natsu considered how the Void Demon Fox’s senjutsu would gradually strengthen the body and soul rather than merely provide a temporary combat boost.
  • Uchiha Natsu planned to teach the senjutsu to Fugaku and compile his training into scrolls for clan members who could awaken Susanoo.
  • Uchiha Natsu decided that women from outside clans could marry into the Uchiha Clan, while outside men seeking Uchiha women would need to prove their worth and gain approval from at least five clansmen.

  • Whitebeard declared that he would destroy Marine Headquarters to save Ace, and Shanks warned him that Blackbeard's plans were more dangerous than they seemed.

Ch. 134New Plans, a Human Test Subject

Natsu planned to use Whitebeard as the first human test subject for Hashirama Cell transplantation, hoping to restore his health and gain the Whitebeard Pirates as allies or subjects. After discussing the plan with Fugaku, Natsu headed toward Fish-Man Island and approached the Whitebeard fleet, where a lookout spotted him running across the sea.

Natsu offered Whitebeard a risky transplant of Hashirama Cells to restore his failing body, and Whitebeard agreed to trust him with his life. Natsu prepared to take Whitebeard to Origin Island, but their attempt to connect was interrupted by the vast difference in their heights.

  • Natsu explained the Hashirama Cells’ regenerative effects and warned Whitebeard that the transplant had unpredictable risks, though the chance of success was above fifty percent.
  • Marco protested that the transplant was untested and could leave Whitebeard unable to reach Marineford, but Whitebeard described his failing condition and the strength needed to save Ace.

  • Natsu inscribed a Flying Thunder God formula on the Moby Dick’s deck and told Marco to take the fleet to Sabaody Archipelago and wait for them.
