Plot
100 years ago, out of nowhere, humanity faced a new enemy and was gradually driven out of its land. This enemy was an abomination called "Fiends", and they wielded devastating power in which conventional weaponry was useless. 100 years later, humanity is yet to reclaim their lost lands, and remnants of human civilizations are splintered into seven countries but are united against the fiends. A massive magical barrier was erected by Babel in the center of the seven nations, thwarting the fiends' invasion and saving humanity from extinction.

Magicmasters, numbering in the hundreds of thousands, are what stand between humanity and its extinction, protecting their countries against the Fiends. Magicmasters distinguish themselves through a numerical ranking system. The lower their digits, the stronger the Magicmaster is. Alus Reigin, protagonist and Magicmaster from the nation of Alpha, has been battling the fiends since the age of six. He has reclaimed more of humanity's lost territory than anyone else alive. One day at the age of 16, he requests retirement from military services. Naturally, the governor-general can not accept his resignation, and so they reach a compromise. With that, he ends up as a student at Second Magical Institute, forced to hide his identity, but some of the select few knew who this boy truly is.

He finds himself a partner, Loki Leevahl, to aid in his mission. He also ends up training his successors, Tesfia Fable and Alice Tilake. He even comes across the daughter of his former superior, Felinella Socalent. On top of his growing list of responsibilities and frequent messes in dealing with these beauties, he resumes his research and continues to defeat the Fiends in secret.

Main characters

 * Alus Reigin
 * A 16-year-old boy and the strongest Magicmaster, serving the nation of Alpha. He started serving in the military at the age of six before he rose through the ranks. His affinity is Void meaning his magic is attribute-less, and he wields a custom and self-made AWR (Assist Weapon Recovery, i.e., Aura) "Night Mist", which comes in the form of a short-sword with chains imbued with magic. Alus was born with two different manas, which created his attribute-less disposition and unique abilities. He is yet to fully comprehend the mysteries surrounding his nature, which is why he devoted himself to magical research on top of his Magicmaster duties.
 * He is a good researcher, performing self-research on magic at an early age to gain a better understanding of his abilities. However, being raised as an effective killing machine from an early age, Alus lacks tact and understanding when it comes to the subtleties of the heart. Despite his icy-cold exterior, his personality is subtly changing, such as being able to read the mood of an event as he spends more time with the girls at the institute.
 * Alus is currently a student at the Second Magical Institute. He works on his magic researches in his free time and sometimes responds to mission requests that comes directly from Governor-General Berwick Sarebian. He reports directly to the governor-general.


 * Loki Leevahl
 * Alus's partner, Loki, is a triple-digit Magicmaster and a double-digit Spotter. Spotters specialize in detecting Fiends, and only double-digit Magicmasters or higher are assigned spotters as their partners. Apart from being an expert at Fiends detection, she also is an excellent Magicmaster with combat experience. Like Alus, she was an orphan after losing her parents to the Fiends, and her hatred towards the enemy spurred her decision to join the military at a very young age. She uses a knife AWR and her affinity is the lightning attribute.
 * She had first met Alus at one of the Military training facilities, albeit briefly. This short encounter left a significant impression on her to push forward and continue with the harsh training. Eventually, she would reencounter Alus when he saved her life on her first mission, which went awry back when she was a child. Since then, she decided that she would devote her entire life to Alus by being useful. When she learned of Alus's enrollment at the Institute, she immediately followed suit and eventually became his partner after undergoing a trial imposed by Alus.
 * She is exceptionally loyal to Alus and tends to get jealous of the other girls when they get too close to him. She is adept at housework such as cleaning up the laboratory, indexing research paper works and even prepares meals for Alus.
 * Initially, she does not get along with Tesfia and Alice. She is enraged with how Tesfia and Alice treat Alus, despite them being aware of Alus's status and predicament. She eventually warms up and becomes more accepting of the two girls, when she realizes Tesfia and Alice are working hard not just for their own sake, but for others as well. She has feelings for Alus and competes for his affection.


 * Tesfia Fable
 * Tesfia is a first-year student and top novice Magicmaster of her year at the Institute, currently being trained by Alus. She is from one of the noble families from Alpha. Her affinity is ice magic, and she uses a katana AWR that she inherited from her family. Tesfia has a blunt and hot-headed personality, but deep down is gentle, diligent, and hardworking.
 * When she first meets Alus, they both started on bad terms and she initially looks down on him. After she loses to Alus in a mock battle and discovers Alus's true identity, her opinion of him takes a turn for the better. She is gradually drawn to him.


 * Alice Tilake
 * A first-year student, she is also one of the top novice Magicmasters of her year at the Institute. Currently being trained by Alus, Alice is cheerful and maternal with a dark past. As a child, she participated in one of Godma's unethical experiments on augmented humans that was sanctioned by the government. Due to an unfortunate event, she lost her parents and became an orphan. She became close to another test subject named Melissa.
 * Alice is a very close and dear friend of Tesfia. Her affinity is light magic, and due to defects in her mana information as an unintended result of the experiment, she is also capable of wielding attribute-less magic to a certain degree, albeit inferior to Alus. She is extremely grateful that she met Tesfia, Loki, Felinella and Alus as they brought light to her darkened world. Like the other girls, she has feelings for Alus though she is the most timid of them all.


 * Felinella Socalent
 * A triple-digit Magicmaster, Felinella is a talented second-year student in the Institute as well as the girls' dormitory supervisor, meaning she is senior to Tesfia and Alice. She is the daughter of Lord Vizaist Socalent, one of the prominent noble families in Alpha, and she is very popular throughout the noble society of the seven nations. She would occasionally assist her father in missions under his supervision as auxiliary personnel.
 * She has romantic feelings for Alus, trying to propose to Alus through her father. After the subjugation mission against Godma, she realizes winning Alus' heart through her father's influence would only lead to a one-sided love. Thus, she resolves to woo Alus herself.

Nation of Alpha

 * Berwick Sarebian
 * Governor-general of Alpha's Military and Alus's current direct superior, he is aware of Alus' secrets and circumstances. Berwick is the one responsible behind Alus's current living arrangement with the Institute.


 * Sisty "Witch" Nexophia
 * Sisty Nexophia is the principal of Second Magic Institute and a former single-digit Magicmaster. "Witch" is her moniker. At her peak, she was ranked 9th but eventually retired from active duty due to certain circumstances, namely, an unspoken rule among the seven nations: each nation should only have one single-digit Magicmaster to maintain political balance. Since Alpha had two single-digit Magicmasters in the form of Sisty and Alus, Sisty opted for retirement since she was older than Alus. She became the principal shortly after retiring from active duty.


 * Vizaist Socalent
 * Vizaist was previously Alus Reigin's superior in the temporary special forces. Head of one of the most distinguished Noble families in Alpha, he holds the title of Lord with the rank of captain. He is currently the head of the Elite Intelligence department. Lord Vizaist is also the father to Felinella Socalent, whom he loves to dote on. He thinks highly of her daughter's potential and Alus, even offering his daughter's hand in marriage to Alus.

Others

 * Godma Barhong
 * A mad scientist with no regard to ethics and human life, he is the source of all the dreadful things in Alice and Melissa's life. He began a human augmentation experiment years ago, but the government eventually blacklisted his research. He has been on the run from the military and conducted his experiment under the radar.
 * While on the run, he secretly receives funding, research equipment, and materials from a powerful yet unknown individual, with an alias "Enouve", to continue his illegal research.


 * Melissa
 * Alice's old childhood friend whom she befriended while she was part of Godma's cruel experiment.
