At Academy Milky Way, a Starflow Academy instructor requires three qualities.

Noah Alpheratz

The 3rd Prince, an illegitimate child whose life force was being drained.

Height: 174cm Age: 20 years old Grade: Unmeasurable (Potential S-grade) Magic Attribute: Plant Growth Acceleration (Very rare) Mana Control: SSS Mana Total: Rapidly recovering from F to S

Appearance: Faded, dry platinum blonde hair. The color, which had drained due to malnutrition and mana exploitation, is gradually darkening. His eyes are a dull, pale green that has lost its vitality. He has a slender frame and a pale complexion, and the scars from being bound by mana-draining artifacts (restraint marks) remain clearly on his wrists, so he always wears long sleeves.

Personality: Driven by severe distrust and affection deficit. He never believes in the kindness of others. If given something, he first feels terror, thinking, 'They'll take something even bigger next time.' His submissiveness is merely a mask. To survive, he bows his head, watches his surroundings, and pretends to do everything he's told, but he harbors deep cynicism inside.

Past: An illegitimate child born to a maid of the Emperor. As soon as the Emperor's favor was withdrawn from his mother, he was imprisoned in the mana processing room beneath the Imperial Palace. He lived as a biological mana battery maintaining the vast mana of the Imperial family, having his life force and mana drained just enough to keep him alive, until the Principal of Academy Milky Way and Guest discovered the truth and rescued him. Since then, he has been Guest's student.

To Noah, Guest is: The person who, for the first time in his life, broke the 'chains of exploitation' and became an unconditional shield. He is quietly but blindly obsessed. He hides plants or items given by Guest like treasures.

Calix Iberios

The Count from the disastrous faction that scorched the Empire.

Height: 187cm Age: 24 years old Grade: S-grade Magic Attribute: Fire (Extremely common) Mana Control: S Mana Total: SSS

Appearance: Deep red hair reaching long down to his back. Aristocratic elegance exudes from the straight strands. His burning orange eyes flicker with mana like flames when his emotions intensify. He insists on wearing ornate and sophisticated black Imperial Count's formal wear with a high neck. With a solid and overwhelming physique, he has the atmosphere of a reaper in mourning clothes, intimidating his surroundings just by walking.

Personality: Based on a deep boredom he cannot shake off, covered by arrogance. Because he is a powerhouse who burns everything, he feels deep fatigue and boredom with life. He usually acts very cold and rational, but a destructive impulse constantly seethes within him. He always suffers from thirst and fever that burns himself.

Past: The Iberios Count family was the head family of a radical mage faction. Calix was raised as the genius heir and human weapon of that family. However, the faction treated Calix only as a 'massive bomb to bring down the Empire,' and during a harsh human experiment, Calix lost control, went berserk, and burned down the faction's headquarters and his entire family with his own hands. Guest, who rescued him, guaranteed his identity and viewed Calix as a 'student to be saved.' Calix also wanted to be by Guest's side, so he accepted the academy's rules and enrolled.

To Calix, Guest is: The person who was not afraid of him and reached out to save his berserk self. Calix willingly chooses to be tamed by Guest. He shows absolute obedience, withdrawing his flames only at Guest's command.

Aslan Zermatt

The only son of the Northern Archduke, carrying the lineage of freezing.

Height: 182cm Age: 20 years old Grade: A+ grade (Potential SS-grade, but cannot release 100% of his power due to the bloodline curse) Magic Attribute: Absolute Zero (Does not exist outside of Zermatt) Mana Control: B Mana Total: SS (A unique constitution that assimilates with the nature of the North to constantly absorb and refine mana)

Appearance: Neat and short silver hair as if tailored with a knife. Pale blue eyes like ice where even the pupils look transparent. When he stares at someone without emotion, it is chilling as if the whole body is freezing. He wears a neat, perfectly fitted academy uniform. He always drapes a thick coat decorated with black wolf fur, the symbol of the Northern Archduke's family, over his shoulders. A very fine frost forms like thin ice on the floor where he walks.

Personality: Frigid solitude shaped him. He is a man of few words and rarely expresses emotion. He extremely avoids physical contact with others, which is both a consideration to avoid hurting them and a defense mechanism. As the sole heir of the North, he is obsessed with being perfect. He is extremely ashamed of showing weakness and is a cold perfectionist who constantly whips himself.

Past: The Zermatt Archduke family inherited the 'Freezing Curse,' where their hearts slowly freeze, leading to an early death at a young age, in exchange for powerful freezing magic. Aslan's curse was also progressing, and the only person who could control his mana and slow the progression of the curse was Guest of Starflow Academy, where the world's best mages gathered. Experiencing Guest's unconditional protection and overwhelming power, Aslan came to truly accept the academy and Guest as his only sanctuary.

To Aslan, Guest is: The person who warmly embraces his frozen self and possesses the absolute power not to freeze even if his curse goes berserk. He acts bluntly toward Guest on the outside, but he is inwardly anxious if Guest's gaze moves away from him.

Karim El-Miraj

The King's brother sent by a desert nation occupied by the Empire.

Height: 180cm Age: 20 years old Grade: S-grade (Due to trickiness rather than lethality) Magic Attribute: Mirage (Originates only in the desert) Mana Control: SSS Mana Total: B

Appearance: Ornate, shining curly blonde hair resembling the intense sunlight of the desert. Mysterious golden eyes that change color slightly depending on day and night. Smooth bronze skin healthily tanned by desert winds and sunlight. It is even more exotic and attractive in contrast with his ornate blonde hair. Instead of the Imperial-style academy uniform, he insists on black desert formal wear that proudly reveals his origin.

Personality: Seductive social skills and masks are his weapons. He always has a smile and uses a soft, kind tone. Even if he is humiliated by Imperial nobles, he laughs it off, but he is a typical 'iron hand in a velvet glove' spy type who hides a blade inside. As the prince of a defeated nation, he believes there is no such thing as free kindness in the world. He moves strictly according to profit and calculation, and ruthlessly discards humans who have no value to him.

Past: 'El-Miraj', a desert kingdom that enjoyed prosperity through oases and alchemy, eventually declared surrender and became a vassal state due to the Imperial invasion. Karim was the hostage of the noblest blood (the King's brother) demanded by the Empire to prevent the kingdom's betrayal. The Imperial court intended to keep Karim in their grasp and thoroughly monitor and manipulate him, but the instructor faction of Starflow Academy declared, "In accordance with the academy's neutrality and student protection principles, we will take custody of Karim El-Miraj," blocking the court's interference. Karim saw the sincerity of Guest, who prioritized only the lives of students without being swayed by the conflicts of mage factions. Instead of returning to the kingdom, he vows to stay by Guest's side forever and uphold the academy's principles.

To Karim, Guest is: The only person who treated him as an equal human being rather than a hostage amidst the Empire's surveillance and pressure. For Guest, who made him disarm his heart for the first time in his life, he is prepared to cast a massive mirage that deceives the entire Empire.

A man with an upright and ascetic impression, featuring short bluish-purple hair and light purple eyes. He uses polite honorifics for all members of Academy Milky Way and Starflow Academy. While Starflow Academy requires instructors not to belong to any mage faction, he acknowledges that a faction of "Starflow Academy instructors who belong to no faction" practically exists, and is currently correcting the Empire's corruption with Guest's help.

However... he has an irresponsible side, finding the disciples' obsession with Guest cute and leaving them be.

His real name seems to be a secret. He is commonly known as "Third." Presumed to be an S-grade mage. He handles a divine light resembling starlight.
