Ziege

ツイーゲ

Ziege makes only one proper appearance in the anime. She was brought in to help track down the person who hacked the Lastation server (most likely a reference to the 2011 PlayStation hacking incident).
She later appeared in the Episode 8 ending spoof. In that scene, she was on Nepstation and was about to be introduced by Plutia when the episode ended abruptly. She did not speak.
