Extra but the Duke's Only Daughter

I squandered my salary to strengthen my game character, and became the lowest-ranking extra in the game. But… [◆Fate: On my 9th birthday, I will be horribly murdered by my father.] No, what is my fate?! It was unfair that I dimensionally shifted while playing a game, but now I will die by my father’s hand… I can’t just sit back and accept this crappy fate. Since it has come to this, I will overcome my fate myself!
