At some point while she was away, probably a short while before she once again returned, a golden spark was created in mid-air. With each passing second, the size of the spark grew, until eventually it would connect to itself in a ovoid shape. And, at about the time that Asteria walked back through her door, the fabric of reality would ripple, and open a portal. One could look through this portal, straight to the other side. And if they [i]were[/i] to look, they would see some dirty, cluttered alley way. Non-descript, and darkened by shadows. 

From that location, a young man seems to be crawling up through the portal, from the ground, as if he had been laying before. His appearance is likewise tusseled enough to suggest as much. His hair and skin, both appearing normal despite the stripes of purplish silver, were both dirty. His car ears lazily announce his current form. Yet, in contrast of that and his rather ragged looking clothes, he wore what appeared to be light armor, made of shined bronze. 

The cat boy flopped the rest of himself onto the floor, and laid still for a moment as he took in his surroundings, and the girl infront of him. Then he would burst out laughing, "Oops...wrong location~" 

However, the portal would close behind him quickly, giving him no option to backtrack.
