• Izuna returned to Konoha after a survey mission and gave gifts to Hashirama Senju, Madara Uchiha, and Tobirama Senju.
• Hashirama Senju, Tobirama Senju, and Madara Uchiha debated whether Izuna was real, since Madara had seen his brother buried and confirmed his remains were still in the coffin.

Meanwhile, Madara convinced Hashirama and Tobirama to hide the truth about Izuna’s parallel-world origins while they searched for a way to send him home.

Meanwhile, Izuna privately celebrated the rise in his act’s credibility and began checking what other abilities his body might have, ending with the memory of “Rhythm Game.”

• Izuna recognized that the listed disputes resembled work he had handled as a comic convention organizer and drafted proposed solutions for them.

The chapter ended with Izuna setting out to explore the clan compound and Madara quietly supporting his choice from home.
