Taiseki

Taiseki was a Rock ninja during the Third Great Ninja War. He is also a character who appears in Kakashi Gaiden only.

Taiseki served as a guard in the war. When his comrade Kakko felt the team of Kakashi Hatake, Obito Uchiha and Rin coming near, he and his Kakko attacked them and captured Rin. Kakkō used a Genjutsu on Rin, trying to get information out of her, but it didn't work due to Rin's strong will. Later, Kakashi and Obito came to save Rin. Taiseki used his invisibilty technique to attack Kakashi and wounded him. Shocked by seeing Kakashi getting injured, Obito awakened his Sharingan. Because he could see the chakra flow of people, Taiseki's technique didn't work anymore on him and he could kill Taiseki with one strike with his kunai.
