Tenma Izumo

was a member of Team 2 and a team-mate of Itachi Uchiha; however, the two did not get along well.

Itachi Shinden: Book of Bright Light
When Tenma and his friends learned of Itachi's success in the Academy even though he was four years younger than them, they tried to bully him, but he simply ignored them. As he attempted to mimic his parents' belief that the Uchiha Clan orchestrated the Nine-Tails' Attack on Konoha, Izumi Uchiha stood up for Itachi and activated her Sharingan to scare him and his friends off.

At graduation, Tenma was placed on Team 2 under Yūki Minazuki's leadership alongside Shinko Inari and Itachi, much to his annoyance. During their time together, Tenma constantly tried to belittle and outdo Itachi, only to constantly fail even though his sensei and Shinko tried to stop him from doing so.

Thanks to Itachi's skill, Team 2 was given the ceremonial honour of being the Fire Daimyō's guard during his annual trip to Konoha. During the trip, a mysterious man in a black cloak and orange mask attacked the caravan, placing all but himself and Itachi in a genjutsu. While Itachi was cautious, Tenma ignored the warnings and attacked the mysterious man, only to realise he was intangible and was brutally killed.

Personality
Tenma was a haughty and prideful child and did not take others outshining him well. When he and his friends saw that Itachi, who was four years their junior, was already graduating with them and hailed to be better than them, he did not take it well at all. When he was placed on a team with him, Tenma's own attitude refused to change and ultimately it was his refusal to work with Itachi that eventually cost Tenma his life.
