Taiseki (タイセキ) was a shinobi from Iwagakure who fought and died during the Third Great Shinobi World War.
Personality He was quiet, unlike his partner. He was also very cautious, as he took his battle with Kakashi and Obito "nice and slow", even if they were kids.
Background He formed a team with Kakkō, using their superb diversionary tactics to attack the enemy. With his Hiding with Camouflage Technique he was able to approach his enemies from their blind spot, easily killing them with a single strike. He confronted Team Minato, led by Kakashi Hatake, during the Third Great Shinobi World War, managing to take Rin captive. He was later killed by Obito Uchiha, however, while he and Kakashi attempted to rescue Rin. Taiseki also injured Kakashi's eye, leading to him gaining his Sharingan from Obito.
