Koji Majima

Came from a line of doctors, befriended Mana and idolized Kino. When Ryou was injured after a fight with Another Agito, Koji was told by Tetsuya/Shoichi to give Ryo his Agito seed in order to save his life. As he gave up his power, Ryou was not only completely healed, but was able to access Exceed Form. He is the only surviving member of the Akatsuki by the end of the series. Other people who were in the Akatsuki incident were Jun Tachibana, Masahide Takashima and Kazuo Ashihara.
