Dramatical Murder - Season 1 Episode 11 Data_11_Fixer
6.30 24 minutes 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.
