But I'm a villain!? (mha/bnha oc story)

"If I can't be a hero, I'll be a villain..."
Kagetsu Bakugou, twin sister of Katsuki "Kacchan" Bakugou, had wanted to become a hero for years. But she had always been inferior to her twin, seeing as the explosion quirk the both possessed was weaker in her. Always being told that she could never be a hero if her brother was a competitor took a toll on Kagetsu. Because she was shunned by most, she became close friends with none other than the "quirkless wonder" Izuku Midoriya.
When her brother went to UA Kagetsu was devastated and that's when her life went wild. She decided that if she couldn't be a hero, she'd be a villain.
