Here in the shinobi world there is love and despise. The contempt in this world will develop in all shinobi and what is reflected in this world are the Great Ninja Wars. These great ninja wars dragged on for many years. As the first reincarnation of Kishi Otsutsuki and Hirai Otsutsuki, the descendants of the Sage of the Six Paths. The Sage of the Six Paths, the creator of this world, longed for harmony in the final destiny of the shinobi. At the time the Sage of the Six Paths died, he asked Kishi to give people chakra and start a pattern of harmony. Kishi's brother Hirai wanted to take up arms against the world, later he founded a tribe called Uchiha at that time, Kishi then founded his own tribe called Senju. And then, around the Shinobi period, Both Kishi and Hirai died of illness.
Decades later, two shinobi were born into this world, Fujino Senju and Samaru Uchiha. The rivalry between these two shinobi clashed for decades. Eventually Samaru Uchiha was defeated by his rival Fujino Senju, Fujino was well known in the Great Nations, to be the "God of Shinobi" in his time. The first ancestor of the Senju was the Sarutobi clan. The Sarutobi clan were Senju overseers to watch over the Uchiha and the village. The first descending ancestor of the Uchiha was the Hagoromo clan. The Hagoromo clan was known as a security team that assessed any risks or security threats that might affect its clan. An agreement was reached in which both clans would accept peace and moderation. Both Fujino and Samaru then created the village they wanted to make. The village was called Hyōgagakure, the village hidden in the glaciers.
After a year since Hyōgagakure's inception, a presence of "hatred" was building in the village, waiting to be unleashed. Fujino, the First Hokage, was wary of Samaru's movements and ordered the senior jonin to keep an eye on him. After keeping an eye on Samaru, the First Hokage had a secret arrangement. As they spoke to clarify the village's safety, Fujino sensed that Samaru was being sneaky, so Fujino confronted Samaru, accusing him of having threatened the village with disclosures. Samaru laughed as he agreed with what Fujino said and then displayed his Eternal Mangekyou Sharingan. Fujino was stunned by this power. Samaru now summoned what shocked Fujino even more, he now summoned the Nine-Tails Fox.
With the nine-tails unleashed rampaging through the village, destroying and killing everything in its path. Only a shinobi could truly defeat Nine Tails and Samaru Uchiha. While Fujino and Samaru were fighting each other on the other side of the village, an Uchiha outbreak had scared Raiden Senju, Fujino Senju's younger brother. Raiden Senju and his team of 3 included Toshiro Sarutobi, Asuda Hyūga and Sakino Fūmo. When Fujino and Samaru fought, a giant humanoid avatar of Samaru's chakra that surrounds him is known as Susanoo. Susanoo's sword with a single cut can destroy multiple nations, shatter 15 mountains, and possibly with enough power cut the Earth in half, but that was rumored on the Uchiha stone tablet located at the Naka Shrine where Fujino and Samaru had their secret agreement.
After the Susanoo was unleashed, Fujino had no choice but to KILL his old friend Samaru, Fujino, who then revealed his wise power. No one knew of this "wise" power that Fujino had revealed, at that time Samaru's heart stopped beating for a millisecond and then he charged at Fujino. Being a "god of shinobi," Fujino had really shown his skills to the village and all of the Land of Glaciers. Wood Style: Wood Golem Jutsu appeared as a Wood Golem under Fujino's feet. He then charged at Samaru's Susanoo and broke through the armor plates attached to the Susanoo. Within the given time, Samaru merged the Susanoo with the Nine Tails. With all nine tails wielding Susanno's sword and tail beast bombs, Samaru was declared invincible to the shinobi world and his name spread among the five great nations.
