Snow
Madara ran through the forest, eyes spinning as he ran in the direction Izuna had flared his chakra in. It was close enough where he knew Izuna could make it home, but when his brother's chakra stopped moving toward the compound for more than 5 minutes, he panicked. The snowflakes kept sticking to his hair and prickling his skin as they melted against it but he kept moving.
He grabbed a kunai and quieted his approach, stealth being the best weapon of any shinobi.
"...ome Izuna. Wasting your time…" Madara looked around and the ground was painted in hues of red, the new snow making some areas look pink.
A bloodbath and the 10 bodies strewn about made it.
"No I will not. Stop that, you will keep talking to me, you are not passing out here and dying after the stunt you pulled."
"Was nothin.. Simple… child safe?" Child? Madara looked over again and saw the headwrap on one of the disembodied heads with a now bloody symbol on it. That's the rogue nin group we have been trying to hunt down! Child hunters and bloodline thieves.
Madara slowly changed the angle he was at so he could get a better look at who Izuna was with….. Is that Tobirama Senju?!
"Yeah, and has been asking about you for weeks. What did I say about closing your eyes, no closing them or I swear to Amaterasu I will dye your hair some ridiculous color like pink." Did he sound panicked? How bad is that wound?
Must be bad enough to cause Izuna worry. Doesn't Tobirama heal? I swear I've seen his hands glow green across the battlefield.
"Now, tell me again why you saved him in the first place."
"Nnnnnn…So tired…"
"No passing out on me now, so tell me again."
"Children…don't deserve that… he- bright future. Good kid. Kids are future. Protect the future. Peace for them. Always for them." Right then is when Madara jumped down and joined his brother, he may not be the best healer but he was still better than Izuna who couldn't heal at all.
"M'dara?" He looked to the dazed look on the Senju's face- happuri cracked next to him, hair down and most of his armor broken off or removed. So many bruises. Like this, the famed Demon of the Senju, Bane of Butsuma looked… softer? Less menacing, and the dopey smile on his face wasn't helping.
"Mmm… your chakra s'warm… feel great. Always feel great…. In bad times… reach for it." People say my chakra is too overbearing, to hot and all consuming.
"Well you can feel it more if you live. Now tell me more about your idea if peace." His eyes were drooping again but Izuna forced them open.
"Is 'nija's dream.. Always working for it… village for all…"
There was a lot of having to rewake him, but once Madara let his chakra loose to warm the area, Tobirama let them heal him enough to bring back to their compound while he sent word to Hashirama… along with a signed copy of the treaty. One that he was now seeing was written by a different hand than his friend. But close to the farewell letter they found in Tobirama's fist, a note written in blood.
