Vallen announced that the second-generation enhancer, Light of Susanoo, greatly shortened the time needed for Mangekyo Sharingan users to reach the Sage Mode threshold. Natsu reviewed its temporary side effects and ordered a cautious rollout, beginning with Yashiro and Izumi.

• Vallen reported that Light of Susanoo had passed its final live-subject trial and could reduce the Sage Mode threshold period to under a month for most recipients.

• Natsu prioritized the Night Owl Guard and Nightingale Guard for treatment and required every recipient to be observed at the Uchiha Research Institute for a week.

• Fugaku's Complete Susanoo lasted more than three hours ten days after his injection, while Origin Island's Uchiha trained toward Sage Mode in growing numbers.
• After Natsu explained the Broken Anchor, Fugaku advised him to take Yaoyu and Yakumi along because they had both mastered Sage Mode.

Natsu, Yaoyu, and Yakumi returned to the Ninja World and found themselves near Konoha, where they sought information from a passing convoy. When the Grass Ninja captain threatened Natsu, his hand suddenly stopped obeying him.

Natsu, Yaoyu, and Yakumi entered this world's Konoha unnoticed, with Yaoyu and Yakumi eager to prepare a destructive welcome gift. As they walked toward Naka Shrine, Natsu observed the peaceful cooperation between the Uchiha and Senju Clans and considered the score he still had to settle with Konoha.

Natsu, Yaoyu, and Yakumi explored newly founded Konoha and learned that Hashirama and Madara shared leadership, with the Uchiha and Senju holding equal authority. They headed toward the forest training grounds while observing signs of cooperation between the clans.

• Madara recognized Natsu's Sharingan and identified the three as people from Flame Ninja Village, then asked what they were doing in Konoha.

• Hashirama ordered everyone not to fight in the Hokage Building, and the room settled enough for Tobirama to resume reviewing documents.
• Hiruzen Sarutobi and Shimura Danzō entered with documents, and Yaoyu and Yakumi drew their swords as their killing intent pinned Danzō in place.
