While the students are finishing up the X-3 engine, they realize they need a final, very expensive piece. Angelina (a.k.a. Hanako Hattori) and Iris attended a pilot conference, and miss their flight back to Mars. Nagisa arranges for the two of them to board a private company plane, carrying a famous space engineering professor. Hanako and Iris realize the space plane has been hijacked, which is relayed to Nagisa and Director Kiryu. Nagisa doubts that the director will handle the situation and asks A-TEC to save them. With A-TEC's help, Hanako and Iris secure the cockpit and set course for Mars. A hijacker tries to shoot at Iris, but the shots end up shattering the front window. This triggers an old memory within Iris, becoming helpless as the plane veers on a crash course. Suddenly, an unknown ship saves them, while Nagisa is perplexed as to who sent that ship.
