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!

With Shinra standing at the front going about her lecture and my classmates focusing on class like always, the daily normalcy was on track. Still on the corner of my mind, I can’t seem to relax. Varvara and the lass Maria had yet to return. 


Shinra had given both of the girls an exception for the class. Since both had a good head on their shoulders, Shinra decided it was okay for them to skip he lesson just this once. I don’t get the logic behind it, so don’t press me for more details. Even I don’t get how Shinra’s brain works. 


It was nearing past their allotted time limit, yet I don’t see even the silhouette of Varvara and Maria. I wonder if something happened? I'm quite worried. After all, this is Varvara we're talking about. She is no doubt a good person, and a bit of a push-over too. But that shyness of hers was her undeniable weakness. I just hope everything went fine.
