How Did a Commoner Like Me End Up in a Royal Academy?! (Blame My Aunt)

Rein Aster is just a scary-looking commoner who wants a peaceful life. Unfortunately, life has other plans. Thanks to a clerical error (or maybe divine mischief), he’s accidentally enrolled in Astrelia Royal Academy—a prestigious institution meant only for nobles of pure bloodlines. His presence alone is a scandal, and the academy’s elite students demand his immediate expulsion.



But there’s just one problem: Rein is an absolute monster in combat.



Having been raised and trained by his terrifying aunt, Lilith Aster, a so-called "Demon Lord" (who’s actually a legendary hero), Rein endured years of brutal training disguised as "character-building exercises." Now, thanks to that hellish upbringing, he’s:



Unfazed by deadly magic, casually walking off spells that would cripple knights.

A natural-born warrior, wielding weapons like an extension of his own body.

So desensitized to pain that academy duels feel like a relaxing pastime.

At first, the noble factions try to crush him. Instead, he crushes their expectations.



Celestia von Ardentia, the prideful high elf princess, sees him as a brute—until she realizes his strength is beyond noble superiority.

Eleanor du Rosette, the cold and calculating half-dragon, suspects Rein is no mere commoner and sets out to uncover his secrets.

Lilia von Helios, the mischievous fox girl, finds him endlessly amusing and attaches herself to him for entertainment.

Seraphina Nachtwald, the feared dark elf villainess, is shocked when Rein doesn’t flinch at her intimidation tactics—and starts shadowing him instead.

As Rein unwittingly shakes up the entire academy, dark forces begin to stir. An underground faction sees him as a threat, and assassins are sent to eliminate him. Too bad Rein just assumes they’re part of a particularly intense training exercise.



And just when the academy reaches peak chaos, the truth is revealed:



Rein Aster isn’t just any commoner. He’s the nephew of the strongest hero in history.



His reaction?

"Wait… my aunt was a hero?! I thought she was just a crazy old lady!"



A ridiculous fantasy romcom harem where the overpowered commoner just wants a quiet life—but accidentally conquers the royal academy instead!
