>>55152969She's the team leader of the local evil team, Team Star. Except they're not actually evil, they're just a gang of bullied students that banded together to form their own clique, which backfired and their debut intimidated the other cliques into dropping out of school, causing the staff to mass-resign out of shame. She took the fall for the team's failures and was suspended for a year and a half, and the admins took the grunts and holed up in camps around the region to await her return.
Now she's back, and wants to end the team so everyone can just put all this bullshit behind them and go back to school. Her team's code dictates she can't order the team to do that, so in incognito she recruits the player to forcibly crush all the admins, and then her, to force the team to disband. The current director of the school takes pity on their plight and instead enlists the team to act as official battle instructors for all students, allowing Team Star to continue as they please.
Penny herself is obsessed with Eevee and its evolutions, and her team is nothing but Eeveelutions. All of them know Baby-Doll Eyes, because she finds Eeveelutions cute. She's not particularly threatening, but she puts on a chuuni show for the camera because she's supposed to be the big boss of Team Star.
