SAI 

Sai Yamanaka is a Chūbu of Konohagakure's Yamanaka clan. Prior to this, he was an Anbu from Danzō Shimura's group: Root. As per standard Root training, Sai was conditioned to remove all emotions and as such, has difficulty connecting with others. When he is added to Team Kakashi as a replacement for the rogue Sasuke Uchiha, Sai begins to learn more about people's feelings and tries to develop his personality and identity by forming genuine bonds and rediscovering the emotions he was taught to suppress.

Sai eventually married Ino, and had a son with her, named Inojin, whom Sai helps train to become part of the new generation Ino–Shika–Chō, with assistance from his wife. The week before Inojin's Academy graduation exam, Sai practices his signature technique with his son. When Naruto and Boruto Uzumaki sparing session interrupts them, Sai tells the Seventh it's petty of him to consider using multiple Shadow Clones against Boruto. Afterwards, Inojin tells him his taste in art is ancient.
