Ryoji Kaji (加持 リョウジ?, "Kaji Ryōji") gives off an impression of being a triple executor, filling in as an uncommon overseer for NERV (Internal Affairs) while covertly examining NERV for the Japanese government, and now and again apparently going about as a cat's-paw both for and against Gendo Ikari and SEELE - also, he seems to have his individual motivation free of any association, hunting down "reality" behind NERV, SEELE and the Human Instrumentality Project. Amid school, he and Misato were partners, yet split up at Misato's request. A long time later, they are brought together on the UN armada shipping Unit-02 and Asuka to Japan. After he comes back to NERV home office, Kaji and Misato rekindle their sentiment after a time of teasing and affront, when Misato admits that she said a final farewell to him in light of the fact that she understood that he helped her to remember her father.
He is in the long run shot and killed by an anonymous attacker in the wake of challenging his superintendents one time too much, yet not before giving Misato data with respect to reality of the Instrumentality Project. His Japanese voice performer is Kōichi Yamadera, and his English voice performing artist is Aaron Krohn.
