The Vision of Youth, Farewell, 999: Part Two
The Conductor and Tetsuro attempted to steer the 999 away from the black hole, but was immobilized by tractor beams from Promethium. In the mean time, Maetel was able to escape, and managed to turn off the tractor beams. The 999 was able to change course and returned to the planet to save Maetel. He ran into Mirai, and stopped her trying to kill herself for failing to persuade Tetsuro to become a cyborg. Maetel appeared, and the three agreed to work together to retrieve the pendant from the Queen. Though this time the plan successful and the reactor began to overload, Mirai was killed in the process. Queen Promethium disintegrated (but presumably not killed) in the final confrontation with Maetel and Tetsuro.

After witnessing the death of his mother and being left for dead at the hands of Count Mecha, ten-year old Tetsuro Hoshino is awakened by a mysterious woman, Maetal. In exchange for only his company, Maetal offers him the ride of his life on the Galaxy Express 999. It is said that those who travel aboard the legendary train to the end of the line can receive a free mechanical body and with it, immortality.
Impoverished and alone, Tetsuro leaps at the opportunity and joins Maetal on a quest that will span the cosmos. As the Galaxy Express 999 makes its way across our solar system and beyond, Tetsuro is drawn deeper into a dangerous universe where peril lurks at every stop.
