Kairi Sanjou (三条海里, Sanjou Kairi), replaces Kukai Soma as the new "Jack's Chair" when Kukai leaves for
Kairi Sanjou
middle school. In Shugo Chara! Encore, he later returns to this position.


Kairi is the younger brother of Yukari Sanjo and was sent to spy on the Guardians. This was not his choice though, Yukari immediately begged him to transfer to Seiyo upon discovering that he had a Guardian Character. Since his sister is busy at work, Kairi takes care of the household work (and his sister) in her apartment. However, when he saw the true meaning of his "missions," he tries to rebel against Yukari, but not before he reveals his secret to the Guardians when they accidentally discover him with Pestering CDs. After Amu convinces him that he needs to do what he truly thinks is right, he switches sides. After they stopped Easter's plan to use the Black Diamond CDs, he returns to his hometown and his place as the Jack's Chair is replaced by Nagihiko Fujisaki. In the anime, Kairi reappears in episode 71 where he becomes Chairman of a Committee, and meets Amu and Tadase, who are both representatives of Seiyo Academy. He is still seeking to improve himself to become a man worthy of Amu.


Kairi is tall, despite being two years junior to Amu. Unlike the spontaneous Kukai, Kairi is intelligent, uptight,
very organized, and blunt about faults. Even with these traits, he is so capable that Amu and Yaya call him "class president" (class prez for short.) He can also become very shy in certain situations. He has a tendency to be the "planner" of the group, ad he usually leads the meetings and instructs what is to be done by each member. He has dark black hair, often looking like a girl and old-fashioned glasses.
