Eru
Eru works as an engineer on the Giftia maintenance team at Terminal Service #1, where she's been for about two years. She's known for being pretty openly perverted—fans often note her habit of trying to grope her coworkers, particularly when it comes to Andie (or Olivia, depending on the source). It's played more for comedy than anything serious in the series.
