A Tale of a Short Life
The next station for the 999 was called Butterfly's Dream. The inhabitants had wings (like butterflies) but they also have a very short lifespan (also like butterflies). They met Leaf and Kureha. Leaf, an artist, was wingless and was shunned by the locals because of it. Kureha was in love with Leaf, but she was also engaged to Hanza. Kureha called off the engagement and went to the forest with Leaf, but Hanza took her back with the help of thugs. When the 999 was about to leave, the autumn wind signalled the end of Kureha and Hanza, but Kureha found Leaf before she died in his arms.

Galaxy Express 999
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.
