During her display, in which only Satsuki can control, she is stopped by a robot named Griffith, which also destroys tanks and people in the process. Inside, a man named Alan Mizuki claims she is a cyborg named Nana-Go, which was shown to him by Dr. Ogami in their early days in college together. The once-friend of Dr. Ogami has now become his biggest rival, after sabotaging an attempt to revive one of his loves, Jamie. Nanako pleads that she is not a cyborg, but a human. Mizuki refuses to listen, and still believes she is a cyborg, because she cannot take the suit off.
