Evil Vampire System in a Scientific City

This world isn't fair. Why am I a level 0?

My parents tell me to go study and forget about my dreams. I get bullied at school and nobody cares, nobody helps me.
One day, I was on the brink of giving up. This hopeless world, this pointless life I lead. Suddenly, <You have the Vampire System>, what was that?

Will I finally be able to stand up to the level 6s of Yokusuka?
I will take over the underworld and make this city pay for all it has done to me.

Authors Note: I have never written a 'systems' novel before, mainly because I never really liked this style but it would appear that this is what people are reading these days. As a result, I have no idea what a 'systems' novel is supposed to be like and thus; this novel will be fresh, new and different.

It'll be something unlike anything you've read before.
