Destructive Red, False Black, Lonely White (The Bonds of URTV)
The variant URTVs Rubedo, Albedo, and Nigredo. The bonds between the three of them were deep, and at first, they acted like brothers with a good rapport. However, everything completely changed after the confrontation with U-Do at the Miltian Conflict 15 years ago. Albedo's whereabouts became unknown after going berserk from being contaminated by U-Do, and the bonds of the three was completely severed.
15 years later, the three came together once again at Abel's Ark: Gaignun whose consciousness had been overtaken by Yuriev; Jr, who proceeded into the Ark in order to stop Yuriev; and Albedo, who appeared as a Testament to recover Abel and the Zohar. After Albedo had finished his mission as Testament, he ordered Jr to initiate the spiritual link. By forming the link, Gaignun's consciousness would be housed within Jr, and Albedo alone would try to co-annihilate with Yuriev, who had been contaminated by U-Do.
However, Gaignun rejected Albedo's decision, and he himself wished for annihilation together with Yuriev. Gaignun saw right through him. Albedo was frightened of loneliness as a result of his immortality, and Albedo's true objective was to unify his heart with Jr.
Moreover, he spoke openly that he himself was the stopping power to the URTVs that had gone berserk, and that he was the existence that was created to spy on Jr. Now he wanted this mission to be over, that was his wish. "Let's play again, the three of us". Just before he was annihilated, Gaignun's spirit-body, which had returned to the form from 15 years ago, smiled. And then, leaving his comrades who had achieved unification, he disappeared within light together with Yuriev. The bonds of the three had foiled the ambition of the man who tried to become God.
