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.

Lately, a certain woman has been acting all cheeky. It has been already a week since Maria was admitted here in the Academy and all has been strangely peaceful. Except from all ruckuses that the confessions from the guys to Maria (which have been all coldly shut down) and all the idolism from the girls (apparently, they made a club that mainly composed of Maria's fanbase), nothing significant happened. 


A certain woman has been driving me on the edge as of late. She made me do all the troublesome school chores that my classmates refused to take. She has been ordering me nonstop with unreasonable demands around the clock. And she made me stay at the campus late when not a soul was left before finally letting me go back home. I can't retaliate as inside the campus, I am nothing but one mere student. And, know this—exactly as she knew my disposition that she's exploiting me to no end.
