"MysticWitchmon." She said matter of fact-ly once they were in the humans house. "My name is MysticWitchmon. Don't call me lady." She lifted her broom up horizontally about at waist height and let it go. It floated there in mid air and she rather nimbly took a seat on the flying broom. She crossed her legs and folded her arms her lips pursing in thought and frustration. "Where do I even begin..." she saighed "I come from a place called the Digitalworld. A world of data and will. In that world there live a great many beings called Digimon. They are what inhabit that world as you humans inhabit this one. I am one of those digimon." 

She faltered, not sure where to go from there. Those were more or less the basics, though she was almost positive it would raise more questions than answers for the boy. "There are actually a great number of worlds besides yours and mine, I was attempting to go to leave the digital world for...personal reasons. I really hadn't meant to come to the human world, but it isn't to surprising I ended up here. Of all the various worlds yours and ours are very closely connected. Some say your world and it's technology and strongly willed imaginations gave birth to mine. It is not uncommon for digimon to sometimes pass over into this world. Sometimes even humans pass into ours, though that is much more rare. And rarer still..." she said pointing to the device her still held in his hand. "Is that. That is a Digivice. When what ever greater powers that be happen to pair a human and a digimon together the human is given that device and receives the title 'Tamer'. It means you and I are connected by fate, and stuck with one another for better or worse. You are my Tamer and I am your digimon."

[i]It also normally means that fate has big plans for the pair[/i] she thought with no small amount of worry to herself [i]but that's not always the case. Could just be that we were compatible and in the right place at the right time. Man I hope that's the case.[/i]

"So...any more specific questions besides 'explanations'? Cause I could go for hours about."
