Aiko Senju

Aiko Senju (千手愛子, Senju Aiko) is a jōnin-level kunoichi from Konohagakure and the leader of Team 12. She is the daughter of Tsunade and Dan Katō, and this makes her Hashirama Senju's great-granddaughter.

Background
Aiko was concieved a little before her father died in the Second Shinobi World War, and Tsunade only has the signs of pregnancy a few days after Dan's death. Aiko was born outside Konoha during Tsunade's travels, and so Aiko was with her and Shizune up to the point where Tsunade went back to Konoha to take the seat of Hokage. After Tsunade filled the seat of Hokage, Aiko was assigned as the leader of Team 12, the same team her relative Momoko Sora was part of.

Personality
Aiko is a cheerful individual who finds positivity in anything. She is protective of her mother and her relatives. Much like Shizune, she gets worked up over Tsunade's irrational decisions, and she is annoyed by her mother's gambling. She thinks of Momoko as her sister, and they share a deep bond.

Appearance
Aiko inherited her mother's blond hair and her father's dark green eyes. She wears her hair up in two buns with the rest of her hair down, much like her great-grandmother's hairstyle in her old age. Her initial attire consists of a kimono-style green dress that has slits on the sides and the back is longer than the front and is outlines with blue designs, and the dress shows her slightly large cleavage. She wears arm warmers of the same colour with blue bands on the middle and they are outlined with blue designs. She wears her forehead protector on her left thigh on a green cloth and she wears dark blue shorts. Aiko wears dark blue boots that are outlines with blue designs. She noticably wears light pink lipstick and has a purple yin seal on her forehead, very much like her mother and her great-grandmother.

Life Force and Chakra Control
As a direct descendant of the Senju clan, Aiko inherited an incredibly strong life force and physical energy, granting her great durability, stamina and chakra reserves. At the same time, as also a direct descendant of the Uzumaki clan, her life force is blessed with immense vitality and endurance, giving her the potential for an exceptionally long lifespan and allowing her to survive most otherwise fatal injuries and in most cases continue battling.

Search for Tsunade Arc
When Orochimaru came to Tsunade years later in an attempt to get her to heal his arms, Shizune and Aiko attempted to persuade Tsunade against it, even trying to convince Tsunade to kill him with their assistance. She later fought Kabuto Yakushi with Shizune in an effort to protect an incapacitated Tsunade and Naruto Uzumaki. Despite their efforts, Kabuto proved too much for them, as he managed to dodge their attacks and incapacitate them, too. Shizune was able to heal both their legs, and left the field of battle with the unconscious Naruto as the three Sannin prepared to conclude their battle. They then returned to Konoha with Tsunade after she accepted the office of Hokage.

Sasuke Retrieval Arc
When Tsunade took on the title of Hokage, Aiko led a team consisting of Momoko Sora, Kaede Tanizaki and Kyo Shiburai to to fill the role as the leader of their team.

Pre-Shippūden Filler Arcs
She appeared in almost every filler arc as Team 12's leader and occasionally as Tsunade's secretary with Shizune.

Hidan and Kakuzu Arc
In the anime, Aiko was present at Asuma Sarutobi's funeral, mourning his loss.

Five Kage Summit Arc
Aiko was later seen with Shizune, Naruto, Sakura, and Kakashi, looking down on Tsunade, who was now in a coma. Aiko was shocked when Danzō arrived and stated that he was the new Hokage. While later attending to Tsunade alongside Sakura and Shizune, Aiko listens on as and is also present when Sai tells Sakura how Naruto feels for her.

Confining the Jinchūriki Arc
Days later, Aiko and Shizune sense a change in Tsunade. Shizune sends one of the shinobi standing guard over them to announce Tsunade's awakening to the Konoha Council and the Fire Daimyō, who were about to appoint Kakashi Hatake as the Sixth Hokage. Aiko is then seen throwing herself on top of her recuperating mother, crying in joy. Aiko later watches on happily with Tonton and Shizune as Tsunade consumes a large amount of food in order to regain her stamina and chakra reserves. As Tsunade demands more food, Shizune tells her that all the food in the Hokage barracks was finished and that more was on its way after seeing Tsunade's gaze seemingly linger on Tonton, which slightly scared Aiko.

Shinobi World War Arc
Aiko is placed within the Third Division of the Allied Shinobi Forces during the Fourth Shinobi World War. Later on, Aiko is seen with her division as a red flare goes off and Kakashi orders them to go the Surprise Attack Division. Along with her division, they encountered Zabuza and Haku who were about to attack the Surprise Attack Division.

After being informed by Inoichi from HQ that Naruto and B were fighting the "masked Madara", Aiko rushes to his aid.

Ten-Tails Revival Arc
She later stood with the remaining members of the Allied Shinobi Forces as they prepared to face their opposition. Aiko was later seen on the battlefield with Naruto and the others and has received chakra from Naruto.
