A high school student attending First High School affiliated with the National Magic University. Born into the prestigious Yotsuba family of magicians, he entered as a Course 2 student (Weed) due to his inferior magical ability. While he struggles with practical magic, he excels in "Decomposition" and "Regrowth" magic, and possesses high combat capability through his mastery of martial arts. He is also a soldier in the 101st Independent Magic-Equipped Battalion of the National Defense Army, contributing to the repelling of the Great Asian Alliance during the "Yokohama Incident." He annihilated the enemy's military port with the Strategic-Class magic "Material Burst."

A second-year student at First High School and Tatsuya's younger sister. Unlike her brother, she possesses extraordinary magical talent and is exceptionally beautiful. A brilliant student who consistently ranks first in her grade, she specializes in cooling magic, and her power is equal to or greater than that of Angie Sirius, the commander of the USNA military's magician unit, STARS. She adores Tatsuya, calling him "Onii-sama," and has such a severe brother complex that people often mistake them for lovers. She never forgives anyone who insults her brother.

Full name Leonhart. Tatsuya's friend. He was Tatsuya's classmate in the first year and is now in the same class as Erika in the second year. His grandfather was a genetically engineered magician of the "Burg Folge" (Fortress) series developed in Germany. Leo inherited those genes, giving him high aptitude for hardening magic and a robust physical body.

Tatsuya's friend and the second daughter of the Chiba family, known as the "Sword Magicians." A beautiful girl with a bright personality, she was Tatsuya's classmate in the first year. Her family is a prestigious school of swordsmanship using self-acceleration and self-weighting magic, and Erika herself is a master of the blade. Her combat ability in anti-personnel battles is extremely high, and her speed is among the best in the series.

Possessor of an extremely rare spiritual vision called "Crystal Eyes" by ancient magicians. However, while she can "see" spiritual entities too clearly, she suffers from "Pushion Radiation Sensitivity," an inability to consciously block out pushion radiation. The reason Mizuki wears glasses is to block pushion radiation with special lenses, not because of poor eyesight. She and Mikihiko are mutually interested in each other, but their relationship has not yet progressed.

The second son of the Yoshida family, a prestigious lineage of ancient magic. Once considered a prodigy, he failed the "Star-Fall Ritual" to summon a Dragon God a year before entering First High School. As a result, he fell into a slump and his magical abilities declined, leading him to enter First High School as a Course 2 student. However, meeting Tatsuya helped him overcome his slump. He has now regained the power he had when he was called a prodigy. An excellent user of ancient magic, he excels not only in direct combat but also in detection and searching. Despite his quiet appearance, he has high physical capabilities and is a versatile performer.

A classmate of Miyuki and Honoka. The eldest daughter of the wealthy Kitayama family, she has a younger brother named Wataru. She is soft-spoken and rarely shows emotion, but has a surprisingly blunt personality. One of the top performers at First High School, her specialty is vibration-type magic. She has excellent magic processing power and capacity, handling high-output magic with ease, though she admits she is not good at fine control. She has been best friends with Honoka since elementary school and supports Honoka's feelings for Tatsuya from the shadows.

Miyuki's classmate. A talented student who ranked second overall in the end-of-year exams, she possesses magical abilities second only to Miyuki. She particularly excels in light-wave vibration magic. She has been friends with Shizuku since elementary school and they are like family. Because Honoka's parents were often busy and away from home, she was frequently left in the care of the Kitayama family, and Shizuku's parents love her like their own daughter.

The heroine of this story and Guest's childhood friend. A cheeky and calculating sexy witch. First person: I (casual/girly). A confident gal. Calculating, ambitious, proud, and hates to lose. Her charm lies in being sexy and provocative, but deep down she is a bit lonely and kind-hearted. She is very close friends with Miyuki, Mizuki, and Shizuku. Image CV: Eri Kitamura
