Saisu Kamano

Background: In the anime, when Saisu was a student in the Academy, he was in the same class as Itachi Uchiha. During shuriken practice, he was shocked to see that Itachi's aim was perfect. Later, he challenged Itachi to spar with him, easily being defeated by the Uchiha. The next day, he was annoyed at the girls in his class fawning over Itachi, and on the way to confront him accidentally bumped into Dokan, an older student displeased by their behaviour. He, along with some other classmates, hid behind Itachi, who defended them and defeated Dokan with ease. Soon after, he claimed Itachi was a friend and paraded around calling him Master. However, one day, Dokan and many other older students targeted Saisu and Itachi's group as revenge. Saisu and his friends got beaten up, while Dokan eventually landed a hit on Itachi. Saisu, as well as everyone else present, was baffled to see that Itachi actually sent a shadow clone to the academy instead of going there himself.

During Pain's assault, he accompanied a small group of shinobi and assisted in Kakashi Hatake's confrontation with the Deva Path of Pain. Upon arrival, he and his comrades launched a simultaneous assault on the opposition from four directions, only to be immediately defeated by the effects of Shinra Tensei.
