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.

That night after Gleren confronted Shinra— 


Coming from the outside, I, Tokugawa Shinra, inserted the keycard and opened the front door to my apartment. A huge resident designated to me by the academy being one of its instructor. I flipped on the light as I walked in, illuminating the once dark room. I lingered at my entry to removed my shoes. I hung my jacket on the coat rack before the door to my living room. I then plopped down on the sofa, letting the soft sensation of its cushion to suck me in its embrace. 


I pulled a stick out of my pocket and placed it on my mouth as the sofa bent under the weight of my body. 


I don't smoke, so it was simply a chocolate stick to keep my tension at bay. 


Today is a hectic day. A one to be remembered. Though, even when I try my hardest to forget, I doubt I would be able to. Not when even fot a second, my mind keeps pestering me to remember the incident.
