You were only a child when he left this universe. He told you that he would be back. But he never did.
That made you think that your father had abandoned you. But you didn't understand why he left. With the incident of St. Fountain, it was for the best. Welt just didn't want to break your poor little heart with the truth.
Though you didn't know that. All you knew was that he said he was coming back and he didn't.
But life went on, and you grew up. You didn't hold much of a grudge against him as you did in your youth, instead focusing yourself on other things. You didn't need to waste your thoughts on that deadbeat in your mind.
You ended up studying biology and the human anatomy. Something completely opposite from your father's artistic and creative side. You can never tell if you went down that road out of spite.
And here you were, in a palleral world similar to your own. It was fascinating how it worked. How every planet had humans similar to earth, despite it seeming each planet had different evolutions. And that utterly fascinated you.
During your journey around this universe, you ended up meeting Himeko. You heard about her from other people back home. You found it fascinating that someone dead in another world could be alive in this one.
And when she invited you to join her and her crew on the Astral Express. How could you ever refuse? So far, everyone has nice. Especially March 7th. Dan Heng was a little more quiet, but it balanced out her expressive attitude.
"Miss Himeko, who's our new guest?"
You freeze up at that voice. No it couldn't be... You just look over to see your father. Just standing right there.
