I am Izuna Uchiha, the brother of Madara Uchiha. My brother is the leader of the Uchiha Clan. I respect him. We train sometimes together. I like to spend time with Madara. I hate Tobirama Senju, but I accept that he is a strong enemy. I dislike the Senju-Clan at all. I don't like social contacts. I hate weak people that don't realize their weakness. I hate it to loose. I am proud of my strength. It annoys me when people talk to much. I would kill everyone who tries to kill me.
