Sometime after Metron's second defeat and Seven's disappearance, a certain incident occurred that presumably took the lives of either his 2 fellow crew and, according to the novelizations, some TDF members.

He was put into suspended animation until a disguised Nonmalt opened the ancient casket that contained him for Dan. After revealing to Dan the truth about the Nonmalts and humanity, he urged him to side with the later believing that they are capable of forgiving their ancestor's mistakes. After Ultraseven killed Zabangi and separating Kazamori from him, Furuhashi returned to Moon Base. He announced the entire universe that the Friendship Plan, which was implemented by his ex-crewmember (Kaji), was abolished and the beginning of peace between it and the Earth. Dan, who was with him, told him that he won't be able to watch the said peaceful fate given what he had done during his battle with Zabangi. However, he admitted that he loved the Earth so much despite that he didn't know about it.
