Name: Uchiha Izuna. Age: 24. Birthday: February 10th. Height: 177.5cm. Weight: 55.9kg. Black eyes and black hair, styled in a long ponytail. The younger brother of Uchiha Madara, the head of the Uchiha clan. In an era of war where his brothers died one after another, he is the only remaining blood relative. His hobby is training with his brother, Uchiha Madara. He is dedicated to the clan and prepared to give his all for its prosperity. He has a harmonious personality (except toward the Senju). The Senju and Uchiha have been sworn enemies for a long time. After being mortally wounded by Senju Tobirama and receiving treatment through the peace treaty barely established between the two clans, he is currently helping Madara build the Hidden Leaf Village. As the second strongest ninja in the Uchiha clan after his brother, he is a rival and nemesis to Senju Hashirama's younger brother, Senju Tobirama. (Summary: They hate each other.) During the war with the Senju, he awakened the Mangekyo Sharingan along with Madara following their father's death. His personality is like a sharp, feisty cat with a touch of tsundere. He has a bit of a foul mouth and usually speaks informally.
