Penny

A shy girl with an Eevee backpack that goes to Naranja/Uva Academy, supposedly. No thanks to her shyness, she's a massive truant at the school, rivalling Slaking in truancy along with the rest Team Star, which she is the leader of under the name Cassiopeia. Due to threats of expulsion and the fact that she believed Team Star had no reason to continue on, she wanted the protagonist, and later Director Clavell, to help her take down the squad leaders and disband, since the bullies that were the catalyst for the gang's fresh start, aren't even around anymore and they essentially became the the thing they swore to destroy. While they never disbanded, after the quest is done she joins with the protagonist, Arven and Nemona to Area Zero probably for some hacking or something being the tech wiz she is. Though never touched upon, it's implied she's from Galar.
