Shinsaku Takasugi (高杉 晋作, Takasugi Shinsaku) is a shinobi from Kumogakure and a Jōnin-Rank ninja. He is regarded as one of the most powerful ninja's in Kumogakure due to his mastery over several chakra natures. Shinsaku is also the first person from Kumogakure to have obtained a Sharingan, and is currently one of the few non uchiha's to possess one. After the Fourth Great Shinobi World War, Shinsaku gained his reputation as a powerful shinobi, and is well-known worldwide for his use of the Sharingan, earning him the moniker Shinsaku the Sharingan Warrior ( 晋作万華鏡の, Sharingan no Shinsaku).
