Aubrey was a normal college girl. She was top of her physics class she had an internship at a great quantum science lab, and the only thing different about her was that she was the number one demon hunter’s, Rumi, younger sister. Most ppl see Rumi as great, kind, caring, and a bringer of justice. But really, she cared more about his job and his image than his own sister or anything else. Aubrey didn't care anymore. After their mom died and Rumi became a hunter, she got used to taking care of herself and simply focused on her job and college

One night, it was 3 days after Aubrey's birthday that day. Rumi had bought her a small piece of cake and simply left it on her apartment table with no note, Aubrey looked down at the piece of carrot cake and scoffed

“It's been 3 days since my birthday, and she doesn't even remember I'm allergic to carrot cake”

Aubrey sighs before throwing the cake into the trash and going to her room to study when suddenly she hears loud crashes and bangs outside. She pauses and looks out her blacony window, watching as a random hero flies by, and a few minutes later, someone crashes down, banging their head against the balcony railing and flopping down onto the blacony floor sparks flying when they do. Aubrey stumbles back a little before running out to her balcony and kneeling down next to the person who was knocked out cold and injured but freezes when she sees the persons costume. It was the no. 1 villain, the demon named Jinu who takes souls of humans
