Ryuto of the Shadows is an immortal S-Ranked Missing Ninja from the Village Hidden in the Leaves and the leader of the Hidden Dawn Village. Ryuto is the strongest ninja ever to live. His strength is on par with the Sage of Six Paths. Ryuto is also a "Dark Sage", able to use dark chakra as sage mode. He is also the only wielder of the Dragon summoning contract, and last wielder of many extinct and new Kekkei Genkai.
Ryuto is a genetically-made human created by Orochimaru of the Sannin as one experiment of three to create the ultimate life form (A perfect body for him to take over.), using the cells of various Kekkei Genkai Holders. When Orochimaru's main lab was found and destroyed by the Sandaime Hokage Hiruzen Sarutobi, Hiruzen had seized all of Orochimaru's work and research that had yet to be destroyed including Ryuto, the other two genetically created humans, and their files on their abilities. The genetic birth of all three was put on hold for 11 years until a week before the kyubi attack, because they were moved from the Snake Sannin's lair to Konoha's research division which slowed their formation. During the 11 year time both Ryuto and the other two genetically created human Hakai Uchiha Hyuga and Yurei no Yoru, were all taken by Danzo Shimura the Shinobi Of Darkness, member of the civilian council, rival to the Sandaime Hokage and Leader of Root. When Ryuto, Yurei, and Hakai were fully created and in a sense born, Danzo raised them as his own, and trained them to become the Ultimate Shinobi. When out on missions around the village cleaning up the streets and taking care of illegal crimes in konoha they got to see the village and how people acted, thus they still had their emotions, because Danzo never put them through the emotional training because he raised them. At the age of nine a mission they went on got ruined when Konoha Anbu showed up and captured them. When they were turned in and cleared from interrogation, The Sandaime added them to his anbu forces, even though they secretly still did missions for root. Ryuto also secretly put undetectable control seals on half of Danzo's Root Nin. Three years later after the Konoha Crush, while all of the regular shinobi force of the leaf was stretched, and Danzo was in a council meeting, Ryuto activated the control seals and fled Konohagakure, with half of root and his team with him.
Since Ryuto was one third of an experiment to create the ultimate life form, he had many abilities, he could manipulate the five elements at an absurd level easily able to use and master all of the sub-elements, he was also born with dark release and light release, thus he was able to use yin-yang release after he mastered both of his bloodlines. Orochimaru also used his research with Dark Chakra, and made Ryuto's body compatible with it, so he naturally drew it in. When facing particularly dangerous opponents that gave him the most amount of trouble he could use Yin-Yang release to temporarily create a dojutsu in his right eye which he could only use for five minutes called the yamigan, the Eye of Darkness. It's a fusion between sharingan, byakugan, rinnegan, and tenseigan. Before he mastered Yin-Yang release to create his yamigan he could only use dark release to create an inverted sharingan which was a fusion of sharingan and byakugan. Ryuto was a sealing master on par and better than even some of the Uzumaki Seal Masters, his Kenjutsu better than the Seven Swordsmen of the Mist, his genjutsu better than most Uchiha, Taijutsu better than Might Guy, Ninjutsu better than Sasuke Uchiha, Stealth better than Naruto Uzumaki. When Ryuto Fuses all of his elements together he creates a style called dark matter that revolves around truth seeking orbs used as energy blasts, weapons, armour, and teleportation.
