Arc 4War and Return
After Hashirama Senju’s death, the great nations invaded, and Tsubasa left for seclusion while the Senju fought across several fronts. Tsubasa returned after breaking through to the Foundation Establishment Realm, found his father among the war’s survivors, and set out to confront the Land of Lightning’s leaders.
- Tsubasa grew close to the Katsuyu Sage, developed medicines and weapons, and became Senju clan head when Hashirama Senju died, but he yielded the position to Akira Senju after a council vote.
- Tsubasa departed for Shikkotsu Forest as the four great nations mobilized, and Tobirama Senju organized Konoha’s forces to defend the Land of Fire and aid its allies.
- Konoha’s armies fought across the Land of Grass, Land of Wind, Land of Water, and Land of Lightning, suffering heavy losses as Tennin Hyuga, Mumei Senju, and many others died.
- Tsubasa swallowed the blood-red pearl in Shikkotsu Forest and reached the Foundation Establishment Realm, then returned home and learned that his father had gone to the front.
- Tsubasa traveled to the Land of Lightning and found Senju Tenpuku after Senju Might and Orochi Senju sacrificed themselves to help him escape.
- Senju Tenpuku gave Tsubasa a letter, arranged his betrothal to Mai Shiranui, and asked him to care for the children of fallen comrades.
- Tsubasa flew toward the Land of Lightning’s army, intending to kill Raikage A and other leaders to end the war.
