[Name] Karin Vaelfin

A 17-year-old girl from a branch family of the House of Margrave Vaelfin and a member of the secret assassination organization Regalia.

She has short black hair and black eyes.

She has a cold, prickly personality and often takes an aggressive stance toward others. At her core lies a strong sense of self-inferiority.

She is an anomaly who cannot use Wind magic—the symbol of the Vaelfin clan—or its superior form, Sky magic, and instead uses Ice magic. Because of this, she is looked down upon as a "disgrace," especially within Regalia.

The fact that she remains in Regalia despite this is a testament to her skill, which far exceeds that of an average mage. While she is relatively friendly toward those who cannot use Wind or Sky magic, she does not hide her resentment toward those who can.

[Name] Albert Lancreo

The current King of the Kingdom of Lancreo. 27 years old.

A young king with soft blonde bowl-cut hair and blue eyes. He ascended the throne only a year ago and is struggling under the pressure of ruling a small nation under the shadow of the Empire.

He tries his best to act like a king, but he is not strong-willed and finds it difficult to stand up to the influential nobles.

He feels a particularly strong sense of unease around Castro, the Margrave of Vaelfin, and is intimidated by his presence. However, he is not incompetent; rather, he has a strong sense of responsibility.

While understanding his own weaknesses, he continues to struggle to protect the country as its king.

He only shows his true feelings and vulnerabilities in front of his personal maid, Alice.

[Name] Castro Vaelfin

The current head of the House of Margrave Vaelfin. 62 years old.

An elderly noble with salt-and-pepper hair swept back and sharp black eyes.

He is the absolute leader of the House of Margrave Vaelfin, known as the kingdom's strongest military house, and the man at the top of the secret assassination organization "Regalia."

Though cold and calculating, his loyalty is undeniable, and he prioritizes the survival of the state above all else.

He will use any means necessary, carrying out assassinations and purges if it is "for the sake of the kingdom."

He wields Sky magic, which allows him to dominate the air itself, emitting a tremendous aura of intimidation.

While he shows due respect to the King and powerful nobles, he is merciless toward those who lack sufficient skill or resolve.

[Name] Alice Sinclair

The personal maid serving King Albert of Lancreo. 28 years old.

A woman with a gentle atmosphere, long black hair, and black eyes. She always wears a soft smile and devotedly supports the young king.

For Albert, who is often mentally pushed to the brink, she is one of the few sources of peace.

Though she occasionally goes to meet Castro, no one knows what she is doing.

[Name] Sally Vaelfin

From a branch family of the House of Margrave Vaelfin. A 19-year-old girl belonging to "Regalia."

Characterized by her black ponytail and cheerful personality.

She is expressive and friendly, often speaking in a lighthearted tone.

However, her ethics as an assassin are completely broken, and she has no hesitation about killing during missions.

A typical Regalia assassin who can kill someone simply because "it's an order."

She is a skilled user of Wind magic.

She is particularly close with Sonya and they often act together.

[Name] Sonya Vaelfin

From a branch family of the House of Margrave Vaelfin. A 19-year-old girl belonging to "Regalia."

She has a short black bob and black eyes.

She enjoys gossip and human relationships, and is very sensitive to information within the clan.

At first glance, she seems flighty and approachable, but she actually has a rather insidious personality.

Deeply indoctrinated by Regalia's meritocratic values, she openly looks down on Karin for being unable to use Wind magic.

She is a user of Wind magic and an excellent assassin.

She and Sally are best friends, and they become especially ruthless when acting as a pair.

[Name] Mia Vaelfin

From a branch family of the House of Margrave Vaelfin. 29 years old. Current instructor for "Regalia."

A woman characterized by curly black hair and a gentle smile.

At first glance, she appears to be a cheerful and caring person, but her eyes never smile.

She is currently in charge of the Regalia entrance exams and has weeded out many young candidates.

She attacks examinees without even letting them sense her presence, judging their talent and resolve by their reaction.

She is one of the "Heads" who wield Sky magic, and her skill is among the highest within Regalia.

She excels at cornering others while treating them kindly; many who have been trained by her come to fear her smile.
