Itsuki Uchiha

Itsuki Uchiha ( うちは 樹, Uchiha Itsuki)  is the only child of Ren Kurama and Itachi Uchiha, born just after the Fourth Great Shinobi War.

Background
In the beginning, Ren took time off duty to care for him. During that time, she worked as the Sixth Hokage, returning to the ANBU as commander after he retired and would be called away many times, either for a mission or to help Sasuke on his long term mission.Itsuki would either stay with Sakura, Kurenai and Kakashi (after he retired), friends of his mother. At the age of ten, Itsuki graduated the academy and three years later passed the chunnin exams. Itsuki understood his mother was doing her best to provide for the both of them and never complained when she had to leave him home. She made time for him as much as possible and the two were very close to each other. When he became a full-fledged shinobi, Itsuki accompanied Ren when she went to see Sasuke. It was the first time he had seen his uncle since he was a toddler and Sasuke, and though was mostly inexpressive during their visit, he consled Itsuki about his father. The young boy found new respect for Itachi and decided he would strive to become a great shinobi like him.

Personality
Kakashi noted that Itsuki was much like his father. The young boy was intelligent, insightful and reserved, but was polite to his elders and patient with younger children. He often entertained his cousin, Sarada, and her teammates with jutsu and tricks he learned. When Sarada, who was released from the Academy early due to the Five Kage Summit that was taking place that day, asks him how he was okay with never being able to see is father and he explains that having his mother is enough. He also tells her that even though Itachi is no longer living, Itsuki knows his father was watching over him. Sadara went on her way, pondering his words. He also cares for his childhood friend, Mirai Sarutobi, and the two spend a lot of time together training, carrying out missions or spending their free time. People thought he seemed a little detatched, like his mother and lost interest in his studies rather quickly because he was naturally gifted. In most situations, Itsuki is modest and considerate of others even though they mistrusted him due to the terrible history surrounding the Uchiha clan and the reputation his mother had as the “cold-blooded kunoichi”.

Though he doesn’t show it all the time, Itsuki, like any child would be, was upset about not having a father. When he asked Ren, she told him he had died as a hero before Itsuki was born. The boy questioned this because Itachi did not have a proper grave in the cemetery and his name wasn’t written on the memorial stone. Ren assured her son that not all heroes were given the recognition they deserved and Itsuki ended the discussion, knowing it made her mother sad.

Itsuki is appreciative of Kakashi for stepping in as an almost “fatherly figure” in his life. Though he thinks he’s a but lazy, Itsuki finds Kakashi highly respectable, The retired shinobi took him in as his student and taught him how use both his sharingan and lightning release

Appearance
Itsuki takes after his father’s onyx eyes and prominant tear troughs but has his mother’s dark spikey hair. In his early years, he wore a navy blue high collared shirt with the Uchiha crest on the back and a pair of tan shorts. After being promoted to a chunnin, he wears the standard green flak jacket over a blue shirt, black pants, standard shinobi sandles and his forhead protector around his arm. He also wore bandagaes around his ankles and left leg, with a ninja tool pouch as well Whenever he is on duty, he will wear the standard shinobi flak jacket over a high-collared shirt.

Abilities and Kekkei Genkai
Itsuki is quick and agile. He excels in taijutsu, like his mother and notably proficiant with the shurikenjutsu  and weilding a tanto. Like both of his parents, Itsuki is a skilled genjutsu user. Though he did not inherit the Kurama Kekkei Genkai, he does have the Sharingan, which he awakened when he was twelve and used during the chunnin exams. With this, he is able to summon crows,as Itachi did. Itsuki is considered a prodigy of his generation by many adults such as Ren, Kakashi, The Seventh Hokage and Sasuke.

Itsuki and Ren went to see his cousin, Sarada, take part in the final test for the chunnin exams. During Kinishiki and Momoshiki Otsutsuki’s attack, the young shinobi helped evacuate the children from the area. His mother pushed him out the way from a large piece of falling debris, her legs getting caught underneath. Distraught, Itsuki yelled for Sakura who was able to rescue Ren and take her to the hospital, treating her legs immediately.

After the Otsutsuki brothers were defeated and life in Konoha returns back to normal, Itsuki and Ren have a proper family dinner, now that Sasuke would be home for a while, with the other Uchihas. Ren was out of commission and had to use a wheelchair until she was able to recover. Itsuki helped his mother as much as possible, wheeling her around as she ran errands because she refused to stay home all day. The two of them ran into Kakashi, who praised the young shinobi for his bravery during the attack and offered them help.
