1. Reo Carter / Leonhardt Caulem
Reo Carter was a feared assassin on Earth, died after eliminating an entire mafia organization single-handedly. After his death, he woke up in the body of Leonhardt Caulem, the disgraced firstborn of the powerful House Caulem Dukedom.
Leonhardt was seen as weak, constantly bullied and ignored by nobles and commoners alike. Now, Reo must live as Leonhardt—using the alias "Leo"—while pretending to be the same useless noble, all to complete a mission that offers him a reward beyond his imagination.
A reward he's willing to do whatever it takes to obtain.
2. Liana
A commoner maid assigned to serve Leonhardt, Liana endured years of mistreatment from the original Leonhardt, who used her as an easy target for his frustrations.
Even though he beat and insulted her, she never left his side, for reasons only she knows.
But after Reo takes over Leonhardt's body, he begins treating her with kindness.
Not just because of guilt, but because she reminds him of someone precious from his past life.
3. Rin Valarune
A quiet girl from Bronze Class 2A, Rin kept to herself, rarely speaking to others. But after Leo helped her with archery training, she began to open up, gradually becoming one of his most loyal supporters.
Leo never thought much of her at first, simply seeing her as a young, timid student.
Her father is a viscount whose business is failing.
4. Erin Dranemount
A mysterious first-year student, Erin is hailed as a once-in-a-century genius.
With silver hair and violet eyes, her combat abilities are unmatched, even Reo was aware of her skills.
Yet, she rarely participates in duels or tournaments, preferring to observe from the sidelines.
Her true motives remain unclear.
5. Elara Valcourt
A graceful, auburn-haired girl from the prestigious Gold Class, Elara is widely admired for both her beauty and kindness.
The original Leonhardt had a disturbing obsession with her—he stalked and harassed her relentlessly.
But behind their lies a deeper secret between them that no one else knows.
6. Darius Rathur
A top-tier student and the current leader of the Gold Class, Darius is the closest friend and ally of Prince Cassian. As a member of House Rathur, which openly opposes House Caulem, Darius holds a personal grudge against Leonhardt.
Known for his imposing presence and deadly combat skills, Darius is considered one of the strongest fighters in the academy. His dark hair and sharp gaze make him all the more intimidating.
7. Prince Cassian
The charismatic first prince of Elaris, Cassian is locked in a power struggle with his half-sister, Princess Thalia, for the throne.
Like many royal family members, he views House Caulem with suspicion and disdain. While he rarely confronts Leonhardt directly, he encourages others to bully him, ensuring his path stays difficult.
8. Princess Thalia
An intelligent and politically ambitious princess, Thalia competes with her half-brother Cassian for the throne—but lacks strong backing.
She is Leonhardt's cousin, the daughter of his mother's elder sister. To strengthen her position, she has set her sights on winning the upcoming student council election, hoping it will increase her influence.
9. Lucian Caulem
Leonhardt's younger half-brother, born from a different mother. Talented, admired, and naturally gifted, Lucian was everything the original Leonhardt envied—which led to deep resentment.
Yet, Lucian has always loved his brother, holding onto hope that their bond could mend. After Reo takes over, Leo begins treating Lucian as real family, finally building the relationship they never had before.
