Neuro, Yako, and Godai arrive to the tanker by a helicopter which is blown up in the process. Neuro enters the digital world of the tanker to pursue HAL. Godai destroys the Sphinx System so Neuro is able to go further in. There HAL is behind his final barrier, a 20 key long password which if typed incorrectly will send nuclear missiles from the tanker and destroy Japan. Yako enters the password and the final barrier is destroyed. Neuro immobilizes HAL and eats up the puzzle. In the real world, the Electronic Drug-controlled Humans break in through the window. Neuro greatly powered by the puzzle commences to defeat (not kill) every single person (20,000 people) on the boat. Meanwhile HAL explains his motive and gives Yako the vaccination for the Electronic Drug. His last request is for him to be deleted before his backup data boots up and make him continue his plan. When HAL reaches 0.00000000001% data remaining, he finds his dead lover in the world between one and zero before disappearing. (thetvdb.com)
