Uchiha Madara left to find his younger brother, Izuna.
Uchiha Jin headed straight for the Uchiha Compound, wanting to see how the clan members here differed from those on the other side.
However...
Once he returned to the compound on this side, he couldn't help feeling deeply disappointed.
There were no transmigrators, no reincarnators.
This was just a primitive shinobi world!
Meanwhile, elsewhere...
The moment Senju Hashirama returned to the compound, he went to find Tsunade. "Little Tsunade, summon Sage Katsuyu right away."
"Uh, okay!" Tsunade was a little bewildered.
Still, she agreed. After all, it was her grandfather asking, and she trusted him unconditionally.
She also knew that her great-grandparent now had an impure world reincarnation body, with no actual blood, so naturally he couldn't use the Summoning Technique.
Poof!
Tsunade cut her palm and summoned Katsuyu.
"Tsunade-sama."
"Oh..."
"Lord Hashirama, you're here too!"
Katsuyu was very polite, though she was still somewhat surprised to see Hashirama.
Tsunade waved a hand. "Katsuyu, my great-grandparent needs to speak with you."
"Lord Hashirama, what can I do for you?" Katsuyu turned to Senju Hashirama.
Senju Hashirama wasted no time. He explained what had just happened, then said with shining eyes, "That visitor from the Other World said the Zanpakuto he carries was a gift from you in that world."
"So I wanted to ask, do you have that sword?"
A Zanpakuto?
The power of the Shinigami system?
Katsuyu froze at those words. Even Tsunade looked stunned, clearly never having imagined that such a thing existed.
However...
After thinking for a long time, Katsuyu spoke again. "Shikkotsu Forest does indeed hold a large collection of prehistoric objects, including a sword whose origins are unknown."
"But I can't guarantee that it's the Zanpakuto you're looking for, Lord Hashirama."
Tsunade's interest was piqued too.
