Sai

Though he has no real name, Sai is a member of Danzo's "Root," a secret group in Konoha that swore to do whatever it takes to protect the village. He is currently in the war against Madara. Married to Ino Yamanaka and had a son with her named Inojin.
Tsunade was pressured into making Sai Sasuke's replacement in Team 7, but Naruto and Sakura were also met by a new group leader, Yamato. They set out to meet Sasori's spy and get information from him, possibly even capture him for further questioning. On their trip the group came to know each other better, but Naruto had already previously met Sai, who attacked him in Konoha.
