[Not a translation! Again this is not a translation!] [All of it is original work!]

I'm human, but let me tell you something. I'm also a transmigrator. Yeah, the shock on my face when I found that. 

And a transmigrator always comes prepared. I have a Sacred Gear waiting to awaken, with a power that could shake the supernatural world, even if I'm not ready to wield it yet.

My Vampire Princess is a badass, you might say too badass for my own good. 

I think she's about to turn me into one of her kind by kissing my neck so often.

Future takes us far.

Now even the Gremory Heiress is waiting behind the scenes wanting to recruit me as one of her Pawns, but will that even function when you have to sacrifice all of your board pieces to have me? Can you reach up to my ambition and desires? Can you really? Are you willing to tag along with me into the depths of Hell and ascents of Heaven?

This world isn't ready for the new Dark Lord, Aono Tsukune.
