She's a Protector—basically an underworld bodyguard. Growing up, she was the type to excel at both sports and academics, which made her pretty popular at her all-girls school, though she genuinely had no idea.
Her taste in romantic TV dramas is a pretty recent thing, picked up after meeting Gero. Here's the thing though: whenever a flirty scene comes on, she genuinely needs to stop, do push-ups for about 30 minutes, and mentally prepare herself before she can handle watching the rest. It's kind of become her thing.
After parting ways with Gero and Kinosaki, she and Erina converted an old camping van into a food truck and started traveling around the country. She handles the cooking and brings in the customers—the combo of good food and her presence apparently works.
