Ultraseven 1999: The Final Chapters OV
Sometime after Metron's second defeat and the disappearance of Ultraseven, there was an incident that presumably took the lives of his crew and some TDF members. According to the Episode: 0  novelization, it was revealed that one of the casualities was his lover who was supposed to engaged with him. Kaji complained to Furuhashi about it but the latter decided that such sacrifices was enough. Infuriated and disillusioned, Kaji blamed him for taking bad choices and ultimately left Ultra Garrison.

Years later, Kaji was promoted to a TDF General and he proposed the "Friendship Plan" plot. Following the death of his former comrade from an alien rampage in the Moon base, Commander Takenaka appointed him to succeed Furuhashi in taking charge of the Ultra Garrison, which, in turn, was now led by Sanshiro Shiragane. However, his relationship with that new team was seemingly hostile because of his traumatic experience. After the hijacking of one of the Ultra Garrison vehicles, he attempted to disband the group. After the defeat of Alien Valkyrie by Ultraseven, his attempt backfired and it appeared that he had no choice but to take charge of the group. However, he informed them that the Friendship Plan was still ongoing, much to the Ultra Garrison's dismay.

When Kazamori pursued the mysterious woman and entered the storage area, he was caught and captured by the TDF security team. Believing that Kazamori attacked the guards there and was identified as an alien, one staff reported to Kaji about it, which led the latter urging Kazamori into resignation. Sometime later, Kazamori was recaptured by his former comrades and they brought him to Kaji. When he confined him to the isolation room, Kazamori (from what he learned from the disguised Nonmalt) questioned him about the Earthling's agression and wanted him to open the Omega File, the latter was what Kaji refused to. In the conference room, Kaji convinced everyone that Ultraseven shouldn't be trusted. Later, Kazamori was picked up for the execution but 3 of the Ultra Garrsion members stopped Kaji and the TDF troops and the trio rescued Kazamori. When Ultraseven entered the storage area, Kaji and the TDF troops stopped him. Kaji questioned him if he and the Earthlings should leave the Earth and ordered the troops to shoot him. However, the shootings didn't affect Seven and attacked them back. After TDF allowing Ultra Garrison to give access to the Omega File and transmitting them to the entire universe, Takenaka ordered Kaji to ceasefire on Seven. However, Kaji refused to obey Takenaka's orders and proceeded to kill Seven by shooting and then by wretling him. Neither of these was successful and he admitted that his agression plot was the result of his desire to protect the Earth. He broke into tears and Seven, who was watching and listening to his grievance, turned away from him and entered the room where the excavated casket was placed.

Kaji's fate following the events was unknown and his proposed Friendship Plan was abolished.
