My Yandere Villainess

My family is renowned as the Family Of Heroes.

My brother, sister, mother, and father- All of them are few of the greatest heroes of today's era.

But although I awakened my superpower already, I chose to not tell my family.

Why, you ask? Because my goal is to not become the best Hero, but to become the best Villain in history!

...Or that was, until I tried to challenge one of the strongest Superhero.

After I defeated her, she fell in love with me?!

Now she won't leave my side! Also, she's so much more scarier and insane than me!
