As Mink and Aoba venture higher up into Oval Tower, Aoba spots specks of light fluttering on Ren's face, but Ren coldly brushes him off. When Mink and Aoba are separated while escaping the guards, Aoba encounters a holographic Sei, who is pleased to finally meet Aoba. Sei explains to the bewildered Aoba that he was one the who sent demos of "Silent Oath" and the invitation to Platinum Jail, guiding him to Oval Tower so Aoba could "break" him with his power. As Sei is at his limit, he encourages Aoba to hurry and come to him before his hologram disappears. Aoba is then captured by Morphine, and learns that Virus and Trip are the leaders of the group. They reveal that they were they ones that erased Aoba's memories of his time playing Rhyme in order to keep him hidden from Toue, as they wanted Aoba to themselves. Additionally, they tell Aoba that Sei is his older twin brother, and both were designer babies created by Toue using Tae's research. However, Aoba was born dead and taken away by Tae to protect him from Toue's experiments, but was revived later on. Since Sei also has the power of Scrap in his eyes, he was kept as a lab rat by Toue and, due to the experiments performed on him, is now on the verge of death. Mink, Koujaku, Noiz, and Clear arrive and rescue Aoba, and Noiz informs him that Ren is infected by a worm. Aoba and Mink press forward to stop Toue while Koujaku and the others fight off the guards. They find a hologram of Toue, who attempts to use Scrap on Mink to stop his plan of dying. However, as Aoba already implanted his words into Mink's mind with Scrap earlier, Toue's attempt failed. Mink orders Aoba to turn back while he runs off to find the real Toue. Ren, becoming more hostile because of the worm, bites Aoba, causing something to flow into him.
