Kairi Sanjou  

, 三条海里

The new J-Chair is a young boy who serves as the leader of the group. Despite being two years younger than Amu, he is very capable and has earned the nickname "class president" from his peers. He wears glasses and prepares for Guardians activities. When Kairi's character changes with Musashi, his hairstyle also transforms to match his new Guardian persona. This boy wields a bokuto as both an offensive weapon and a defensive shield, using it in green color.
