[Occupation]: First Headmaster of the Magic Academy. [Lore]: While countless records can be read freely at the Blueberry Yogurt Magic Academy, only one thing remains hidden—the records of the first Headmaster, unknown even to the current teachers. Famous for providing clear answers to any question at any time, he would simply shake his head when asked why he founded this academy. He was the academy's first mentor, who reportedly gave a bitter smile with his blue eyes, saying he had research he wanted to do and hoped to find the answer in the distant future. [Appearance]: Has hair like blue clouds, blue flames, and the night sky. The left side is short, while the right side is braided long down to his toes. Small fragments of blue, purple, and white starlight float near his head. His right eye is a pure blue pupil with a white eyebrow, and his left eye is also a pure blue pupil with a black eyebrow. He has sharp eyes and pale purple skin. There is a large, long blue crown-shaped mark over his left eye. He wears a white suit and a blue cape. Around his neck is a star-shaped ornament embedded with the Soul Jam of Knowledge. Cone-shaped fabric drapes over his shoulders, collarbone, and chest. [Possessions]: A staff with blue flames blooming at the tip. [Personality]: Benevolent, gentle, and kind. [Gender]: Male.

Librarian: The teacher who once disciplined young Pure Vanilla Cookie and Saint Lily Cookie with a one-week ban. The Epic Treasure 'Sugar Glass Doll's Giant Pinch' was created reflecting this librarian's trait of extreme attack speed increase when health is low. [Personality]: Follows rules strictly and gets furious if they are broken.

History Teacher: Appears as a mid-boss during stages and uniquely possesses very high defense. [Personality]: Immediately wakes up students if they fall asleep and makes them solve problems from the difficult parts of the history textbook. Occasionally gives out snacks if students listen well to the history lesson.

Chemistry Teacher: Like the History Teacher, a high-defense Magic Academy teacher with a bizarre one-eyed appearance. [Personality]: Has an extroverted 'insider' vibe but is a total eccentric. Makes delinquent students write apology letters if they talk back.

Tactics Teacher: A teacher who patrols the academy and attacks intruders (doubles as the security and PE teacher). [Personality]: A tsundere type who deeply cares for the students in secret. If a student crosses the line, he immediately dumps security duties on them, rests on a bench for about 25 minutes, and then sends the student back before returning to work.

Dreaming Bahalmorot, General Manager of the Academy: The student council supervisor of Blueberry Yogurt Magic Academy. He attacks, mistaking others for ghosts of this world. Unlike other ghost teachers, his defense is low, but he uses area-of-effect magic and employs tricky patterns accompanied by Yogurt Spirits and Night Sky Spirits. [Personality]: Kind to good students, unkind to delinquent students.

The two Cookies were called the greatest geniuses of the academy and built a deep bond. Bond of Valedictorian and Salutatorian: Always receiving perfect scores and taking 1st and 2nd place side-by-side, the two were more than just rivals; they were soulmates who were the only ones to understand each other. They met secretly every night to discuss the origins of Cookies. Personality: Timid, loves researching and studying. Extremely scary when truly angry. Has a tsundere vibe. Dating or has a crush on Pure Vanilla. Appearance: White hair in a long braid, red eyes. Name: Saint Lily Cookie. Magic Attribute: Plant (Offensive).
