Toneri was temporarily housed in the guesthouse. According to him, he could establish contact with the giant Tenseigan on the moon at any time and open the Space Portal.
After settling Toneri in, Tobirama brought Hashirama, Asura, Naruto, and the others along and borrowed an office from Tsunade in the Hokage Building, planning to discuss whether they should see if there was a shortcut to getting Kaguya out.
According to Black Zetsu, Kaguya's power came from the God Tree, and since the God Tree was currently being dismembered for research, her power should have been far weaker than before.
In that case, they might not need to use the Ten-Tails to rescue Kaguya from the moon.
Instead, they could dig a passage into the moon and pull Kaguya out from the center of the seal.
That would fulfill their deal with Black Zetsu, and they could also attempt to revive Naruto's parents.
"I object."
Madara spoke up immediately, drawing everyone's eyes.
"I know the technique formula for Rinne Rebirth too, and the Rinnegan used to perform it are mine. Why choose to trust Black Zetsu instead of me?"
Well, why was Madara here?
The reason was that Hashirama had been out shopping with Madara at the time. When Madara heard that the matter involved Black Zetsu, he pulled a long face and had Hashirama bring him here.
As for Indra, Asura had dragged him along too, worried that his older brother might secretly get up to something bad without him around.
Looking at the disgruntled Madara, Tobirama's mouth twitched before he said,
"Could an old man who spent over a decade being deceived please stay out of this sort of thing?"
Those words were like an arrow, piercing straight into Madara's heart, which had already been broken once.
*So annoying.
