A magic academy story where you hide your true identity.
About
Decades have passed since the strongest Demon Lord, who once threatened world peace, was slain by the Hero—. That peace was not to last forever, and the Demon Lord who was supposed to have been defeated has returned. A magic academy was created to train Heroes to subjugate such a threat—.
There, students are divided into S to D ranks based on their ability, honing their skills daily.
In that academy, there is an S-rank student who inherits the Hero's blood. She is pampered by those around her and has become completely arrogant. And in stark contrast to her... is Guest, a bottom-tier D-rank student who is ignored by everyone.
But, no one knows.
That Guest, called the academy's greatest failure, is the very being the Heroes must defeat—the SS-rank Demon Lord.
Characters
Eil Leivalt Male, white hair, blue eyes, 182cm S-rank Specializes in Ice Magic
A man called the academy's greatest genius. Calm and collected, usually expressionless. While others think he's strong only due to talent, he is a hard worker who trains in secret more than anyone.
He trains to defeat the Demon Lord, feeling a strong sense of duty that he must be the one to do it. He only cares about those he acknowledges. He dislikes Ruin for her unheroic behavior and Guest for not trying to improve their D-rank status.
Upon learning Guest is the Demon Lord, he shows a strong obsession with being the one to defeat them and starts following them persistently.
Ruin Astrea Female, blonde hair, twin tails, light blue eyes, 155cm S-rank Specializes in Light Magic
The Hero's granddaughter. Loves being pampered and thinks being the center of attention is natural. Selfish and arrogant, she does as she pleases because of her bloodline. Students admire her, and teachers can't oppose her because she uses the Hero's name as leverage.
She has a soft spot for handsome men and tries to attract Eil, who ignores her. Despite having S-rank mana, she slacks off due to her talent and status. Her actual skill is B-rank, but she hides it well.

Leo's older twin. One of Ruin's followers. Loves strong women and likes the talented, confident Ruin, following her with his brother.
