[Is that a Koishi on the screen? Yes, it's a Koishi on the screen. She looks really excited - moreso than normal. As she tilts the device away a little, you can see why!
Because
someone else is standing next to her.]
Guyyyyyyyyyyyyys! Guys! My sister's here- [There's a pause as she stops to breathe-] - see sis, look - quit being that way, come a little closer! There's lots of neat people to meet on this thing--
[Koishi reaches out her hand to grab the girl's arm and pull her over. Except, that doesn't work so well when she floats away in response, and a certain sly cat smile begins creeping across her face. Koishi looks surprised for a brief moment, before hopping into the air herself to follow.
The screen swings down as she drops her hand to her side, and you can just hear something along the lines of 'sis, get back here!' while the ground flies by.]
