At the far edge of Cedar Village, located between the Lands of Stone and Wind, a former handyman is admiring his new two-story house. It was directly adjacent to his old hut, the former owners were old and recently passed away due to old age...with no one to inherit their wealth, they passed it on to their closest family friend, the young handyman...
Named by his late parents who were obsessed with stories of ninjas, he was called Sonoda Osamu meaning "Chronicler"...a fitting name for the most knowledgeable person now in this world.
...
'It has already been a year...' thought Osamu as he sat cross-legged in the center of a recently drawn fuinjutsu formation, one whose function is not known now since the destruction of the land of whirlpools recently took place, resulting in the death of this formations inventor before he could spread his new invention...
The formation was indeed a marvel and if anyone else in the world knew that a seemingly innocuous village housed such a technique, there would be nothing left of this house within a day.
While Osamu was cross-legged in the center of the formation, black markings spread out in spider web fashion with him at the center leaving only five empty circles. Each of these circles had something different...a pail of water, a candle fire, a pile of dirt, a paper tag causing a gust of wind to flurry around it, and another tag with sparks in the air above it. They were each functioning as mediums to serve the purpose of the whole sealing circle: The reverse nature change in chakra IE: transferring elements back into base chakra...
Osamu was generating massive amounts of chakra each time he performed this ritual, causing his reserves to sky-rocket over the past year, coupled with his extensive training regime and calculated diet and medical techniques, it was extremely effective...
All of these techniques were the best versions that TSW had to offer, causing the once 'eternal genin' to become Jounin-ranked within this one-year span.
.....
After his final exercise for the day, Osamu approached the mirror and looked at his reflection. His messy brown hair and clear eyes were set on an average-looking man. However, he has a unique charm to him while wearing his current apperal. He wore a custom-ordered 'suit' unique in this world and had a diamond mark on his forehead.
His mirror-watching was interrupted however as an exact copy of him came in the window and removed a 'suppression seal' that hid his presence well...
"How did it go? Find the samples?...." the main body asked from in front of the mirror without looking in the clone's direction.
"As we expected, the remains were exactly where they should be. A tooth from the late Tsuchikage Mu buried two meters below ground near his final battle and a bone splitter from his fellow killer, the second Mizukage also close by..."
"Excellent...it's time to head West to the land of toads...Mount Myoboku will be the first..."
.....
Deep within a mountain range laid a 'fairytale-like' land with towering mushrooms and weird-looking toads. In the center of the land, standing in front of a massive cave, a white-haired man is giving his farewells to the small toad-sages standing before him...
"I may not have time to come by and visit in the near future because of the war but I will return..." the man said with sadness and foreboding on his face, he bowed politely in an uncharacteristic show of seriousness as he disappeared, returning to Konoha...
"Jiraiya-boy is a good lad, I'll miss him Ma..."
"Yeah yea, let's go an....PA! The boy forgot his foul books! Reverse summon him back quickly, I don't want those near me!..."
Knowing that making his dear wife angry was not the move, he quickly tried to summon but to his surprise, nothing happened...the seals formed but quickly disappeared....' they're being suppressed, but by whom?'
A huge formation sprung up forming a dome around the main part of the sage region, preventing all space-time travel and exiting, it was similar to the formation of the purple flame but modified slightly...
Pa and Ma heard a nervous murmur from within the cave..." how could I have not predicted this.....PREPARE FOR AN ATTACK!"
Just as the toads readied themselves, they saw two people walking slowly towards them from a distance...one had weird blonde hair and a high-colored coat while the second was wrapped in bandages like a mummy, they looked lifeless but the aura they gave off was something the toads feared greatly....the cracks on their skins spoke of an evil force at work, targeting their home.
