1x11 - Classroom Crisis

While Mizuki begins to nurse Iris back to health in a hospital, Dr. Jason Li finds Kaito, and brings him to a secret research facility. CEO Kazuhisa tells Nagisa his plan to open a military weaponry division, but that he needs Nagisa, Kaito, and Dr. Li to manage it. He also reveals that Nagisa is not even a member of the Kiryu or Shinamiya families, and was instead a decoy as the real Nagisa Shinamiya escaped Mars. Iris, her memory fully returned, attempts to seek out Nagisa. The CEO tells Nagisa to forget his revenge plan and join his side, and Nagisa, lost in his thoughts, finds Mizuki and breaks down. Mizuki tells him they will struggle together, and they kiss. Nagisa and Kaito, not wanting to join the weaponry division, decide to throw a wrench in their plan and re-create A-TEC. Three days later though, Nagisa gets stabbed by former director Yuji Kiryu in a dark city street.
