Taiseki

was a jōnin-level shinobi from Iwagakure.

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
During the Third Shinobi World War, he led a team with Kakkō and Mahiru, 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. They confronted Team Minato, led by Kakashi Hatake, during the Third Shinobi World War, managing to take Rin hostage. He was later killed by Obito Uchiha, however, while he and Kakashi attempted to rescue Rin. Taiseki also injured Kakashi's eye.

Abilities
With his Hiding with Camouflage Technique he can manipulate light around himself with his chakra to become invisible. He uses this technique in collaboration with his great strength to strike his opponent without them seeing him and also to hide from his opponent. This technique can be foiled, however, by anyone that possesses the ability to see chakra.
