Following the world's greatest catastrophe—which nearly led to the apocalypse—the revelation of the skills to utilize magic and supernatural powers were brought to light. They, who were chosen by the stones were called the Ability Holders. 
With the globe entering a new era, an Academy specializing and entirely dictated for ability users was established. At this academy, abilities are evaluated and ranked based on how they influence the world.
Gleren Stasis, a F-rank student at this academy—due to a certain circumstances—was forced to covertly work for an organization that preserves global harmony and balance; a pacifist and a nonchalant boy who would rather idle his days watching anime and play games than to do anything bothersome.
However, one day with the arrival of Maria, the vampire princess—his wishful and peaceful days came crashing down.
Maria as the Last Vampire was a special existence for which she was constantly sought after by her enemies. With such danger always lurking about the Vampire Princess, Gleren Stasis—a F-ranked student at Saint Stella Academy—was tasked with protecting her at all costs without disclosing the truth about himself(?).
Will his life thoroughly change—or will he be the one to change the life of the vampire princess?
This story revolves around the life of an underwhelming boy and the one's he had sworn to protect.

Blood & Shadow; My F-Rank Shadow Ability Has An Unlimited Skill Sets!

I never would have thought that things would come to this. First, the barrier that enveloped the whole school—thanks to that, the class was cancelled. And now, the whole campus was surrounded with people wearing white robes, what's more was that their numbers are insane. They easily surpassed the count of hundred, and that's only within this floor. The students Council came here to warn us and gave us orders not to go out of the barrier they’ve set. However, that idiotic master of mine has run off to somewhere and hasn't returned yet. 


I, Tokugawa Shinra, is worried for that idiot. 


In this type of crisis, no matter how strong you are, if you're surrounded by this many, you can only hold out for God-knows-how-long. Moreover, the enemies this time found a way to stop our abilities from working. In a case like this, we are as if chicks hiding from the rain as we holed-up in this classroom.
