#uchiha things

Imagine.

Orochimaru ressurects the four hokage during the fourth shinobi war. Hashirama does his whole speech, they get told what’s happening out there, the usual. Suddenly, Tobirama stops silently fighting for control as he’s been doing since he felt the connection to the pure lands shut closed.

“If Madara is behind this war…” everyone can see the mental calculations in his eyes, “where did you steal my Edo Tensei Technique from?”

Orochimaru raises an eyebrow. “A laboratory in the northern mountains. The barrier seals were a work of art, a masterpiece of its own.”

“Did you discover any of my other labs?”

“Other?”

The Second Hokage nods continuously, deep into thought.

“Um, Tobirama?” Hashirama asks sternly. “I know that look on your face, what did you do?” Sasuke notes it’s a tone of voice he can vaguely recall Itachi using on him in their youth — an older brother absolutely done with his younger sibling’s antics.

“I… might have an idea. Wait a moment,” and with that, he teleports out of the room.

The non-Kage stare at the empty spot the Second was standing in a moment ago. Minato lights up.

“Oh, wow, I’ve always wondered how it originally looked,” Hashirama turns around and looks at him, so the Fourth explains, “I improved and mastered it. It was sort of my signature?” He adds a bit sheepishly. Hashirama gives him a smile.

“I’m glad Tobirama’s work is getting continued, then. He was always a great inventor, he just sometimes didn’t know when to stop.” He pointedly side eyes Orochimaru, who ignores it.

Then, Tobirama snaps back into the room. He’s holding a vial of a red liquid. The snake sannin looks very attentive.

“Okay, don’t be mad,” he starts, looking at Hashirama (who quickly rebutts “How do you expect me not to get mad if you start off like this?!”), “but I have an idea on how to throw Madara off, if not stop him in his tracks altogether.”

“What is that?”/“Who is that?” Minato and Orochimaru ask at the same time.

“Uchiha Izuna’s blood.”

You could hear a pin drop in the silence that followed Tobirama’s statement. After hearing the tale of the founding of the village, the last thing anyone expected was bringing up an old ghost again.

“What…?” Hashirama’s voice was quiet, and has lost all of the happiness he had when complimenting his brother’s work. If anything, he sounded lost. “How?”

Orochimaru looked as if he wanted to ask the same question. It was fair — in all his career as an amoral scientist, he discovered collecting genetic material from dead Uchiha to be particularly tricky, if not impossible in most cases. It was difficult to get anything from the ashes that remained after their funeral rites, after all.

“The blood from my sword. From our last encounter.”

“From when you killed him,” concluded his brother grimly. “You hadn’t even started working on that jutsu for another decade after that. Why did you do it? Madara would’ve killed you even before he left the village. According to their beliefs, you prevented him from reaching afterlife,” with every work, he sounded progressively angrier.

He was right, though — in the Uchiha belief system, their body was the physical link to the mortal world. It was one thing for Madara to have Izuna’s eyes — given freely and with a long and complicated process behind it non Uchiha were not privy to know much about — and another for an enemy to collect blood to use for experiments (probably?) later down the line.

“You knew that, Tobirama, and you locked it up so no one could find it when you promised me you got rid of all evidence of this jutsu — which was obviously a lie, I can see it now, even if at our first resurrection I was convinced you might’ve missed something and it wasn’t on purpose — what was even the reason?”

“That does not matter now.”

“No, I think it really does.” Sasuke joined in, not hiding the anger in his voice, Sharingan-red eyes ready to make his opinion known with black flames and nightmare visions. “Tell me, Senju, why you knowingly spit on our religion, on my clan, on my kin? Was this your first transgression of the alliance between our clans that build the foundation of this village, or did you break it in another way too?”

I also dont think Tsunade’s inventions helped much with it — her techniques are invaluable, but I reckon they lean more towards injury, operation, and poison counteraction than illness treatment — they were at war, it was their primary concern.

Hashirama… would be more experienced with TB, though, because if there’s an outbreak, he’s one of their best medics. While he goes into field, warring states era shinobi don’t have a luxury of specializing in only one thing, they have significantly less people than Konoha or other Villages do.
