Shai Uchiha had just completed a mission (he's a mercenary) and destroyed a village with his Amaterasu. Sayuri, who was leaving from Konoha at the time, noticed the flames to be the black flames that she also uses, was curious to see who could've produced them. She saw all the destruction, becoming even more curious of who it could be. She later discovered it was Shai Uchiha, and stated that someone of his talents (he had the EMS already) should use them for better causes. Curious, Shai wanted to see what the woman spoke of. Activating her Sage Mode, Sayuri stated that using this power would reduce the strain the Sharingan abilities caused, and asked the Uchiha if he was interested. Wanting to learn more about the strange power, he followed her to the Great Toad Sage. There, he was able to learn the basics of senjutsu, but was unable to merge with the toads. (With the help of Sayuri) Shai was able to develop a natural sage mode (like hashirama) becoming connected to nature. The price however, was that Shai swore loyalty to her (and his group Kanpeki) whenever she needed the services of the mercenary shinobi.
