I, Senju Tobirama, Have Finally Toughened Up!

After Tobirama 2 returned to his own world.

The first thing he did was go into seclusion. With Kagami serving as his sole secret guard, he found an underground base outside Konoha and prepared to begin the Tenseigan transplant surgery.

That's right.

The Giant Tenseigan the Sage had given him, combined with the tens of thousands of pairs of Byakugan from the Moon Otsutsuki Main and Branch Families, had finally become a Giant Tenseigan.

Only a Giant Tenseigan could drive the entire moon and wield power truly comparable to the Six Paths level.

Only a Giant Tenseigan could be fused down into a perfect, normal-sized Tenseigan.

And now.

After a month of frenzied research, with help from the chief scientists of Ninja Worlds 3 and 4, Tobirama had finally fused the Giant Tenseigan in his possession into a normal Tenseigan that could be transplanted into a human eye socket.

He had waited so long for this day!

Once the transplant succeeded and he withstood the Tenseigan's tremendous power, he would be able to match or even surpass Madara Uchiha!

Then.

No one would ever call him useless Tobirama again!

At last, he would trample the evil Madara Uchiha beneath his feet!

For a moment.

Filled with boundless hope and excitement, Tobirama finally began the transplant surgery. The one wielding the scalpel was his own Shadow Clone.

There was no helping it. At a time like this, doing it himself was the safest option.

No one else could understand the Tenseigan as well as he did. Though the other Snake Aunt and Orochimaru could have performed the surgery, Tobirama worried that if he called them in,

the eye socket he was supposed to receive a clean Tenseigan in might instead end up with one smeared in saliva and mucus.

Just thinking
