Tobi's face, the one with spiral markings, was unexpectedly full of seriousness as he spoke those frivolous words.
He genuinely treated "watching Konan use the toilet" as a career...
"..." Obito's entire being, inside and out, simply could not resonate with such vile humor.
But the one making this request was Tobi.
"Since this is your wish, I'll make sure that woman survives."
What Obito did not know was that, as he reluctantly and immorally agreed to indulge Tobi's twisted hobby, Nagato had already used Rin's body to relieve himself more than a hundred times. Each time, he had thoroughly scrubbed and washed every inch clean. Nagato had practically studied Rin's little patch of land inside and out.
It was no exaggeration to say that Nagato understood Rin better than Rin understood herself. The first girl Nagato, who devotedly loved Konan, came to understand was Rin. What a sigh-worthy twist of fate...
Obito and Tobi had arrived at the base's main hall.
Black Zetsu looked at him and grinned. "Obito, you really are something. You transplanted the Hashirama Artificial Body cultivated by Madara, survived, and even turned misfortune into fortune. Your strength has risen to another level. Congratulations, congratulations. At this rate, your power will rival Madara's..."
"Hmph." Obito snorted, paying Black Zetsu's flattery no mind at all.
He had never forgotten that Black Zetsu was an unusual clone Madara had created with Yin–Yang Release. Its purpose in being left behind was likely to watch whether Obito faithfully carried out the Eye of the Moon Plan, guided Nagato's growth, and one day had him use the Samsara of Heavenly Life Technique on Madara.
If not for the fact that... he had no way to erase a body formed from Yin–Yang Release, he would have gotten rid of Black Zetsu long
