Plot
Spica Virgo is a budding witch who admires Claude Sirius, a skilled wizard and teacher who mysteriously vanished one day. However, due to her clumsiness and lack of skills, she feels it is difficult to fulfill her dream of entering Royal Diana Academy, a prestigious magic school where Claude was once a teacher. One day, she encounters a black cat. She is surprised that the cat can talk and asks it for help in entering the academy. After learning that the cat was formerly human but was cursed to have this form, Spica aims to undo the curse. She learns that she has "Rebirth Magic", which gives her the power of regeneration, and that she can undo the curse by kissing the cat's butt. She does so reluctantly, leading the cat to reveal itself to be Claude. With this, Spica enters the academy, with Claude becoming her teacher, with Claude still maintaining a cat form as Spica's magic remains too weak to lift the curse fully.

|
Claude Sirius, the Royal Magic Academy’s youngest professor and First Class Magician, mysteriously vanishes during a Cultist attack and is branded a coward. Two years later, Spica Virgo aspires to be like Claude, despite her inability to cast spells, because he saved her life during the Cultist attack and was not a coward. Spica encounters a talking black cat who claims to be a cursed magician. He promises to teach her if she retrieves the Book of Providence from the Royal Library to cure his curse, a task he cannot do because the library's Mother Grimoire detects non-humans. Finding a book on Ancient Runes, Spica reads the runes on Mother Grimoire, which reveals a hidden library containing Providence. The sentient runestone reveals the cure is Rebirth Magic, which Spica unknowingly possesses, but it must be delivered via a kiss to the cat's anus. When a Cultist sends an Orthrus monster to attack them, Spica desperately performs the kiss. The cat transforms into Claude Sirius, who destroys the Orthrus. Restored, Claude selfishly refuses to teach her, but suddenly reverts to a cat. Providence explains the cure is temporary; for a permanent cure, Spica must match Claude's power, meaning Claude must train Spica into a First Class Magician. | ||||||
| 2 | "Magic of the Zodiac" | Unknown | Unknown | TBA | April 19, 2026 | |

Spica learns magic corresponds to the Zodiac, meaning people only command their birth element. As a Virgo, Spica has Plant magic, but her magic control is the worst Claude has ever seen. When Spica's mother breaks her leg, Claude suggests Spica manage their family farm entirely with magic for six months before her entrance exam. After weeks of labor, her skill and confidence soar. Spica travels to the Diana Academy entrance exam with her friend Aria, an Aquarius who wields Water magic. En route, a golem attacks the examinees. While others flee, Aria destroys the golem, but it reforms. Recalling her time in the Royal Library, Spica remembers golems possess cores inscribed with EMETH (Truth) and erasing the first 'E' leaves METH (Death), destroying it. Claude chides Spica for not fighting herself. Ashamed, she joins Aria, using vines like a whip to slice the 'E' from the core, returning the golem to harmless earth. Vice-Principal Justice Libra appears, revealing the golem was the exam. He passes Aria for her skill and power and Spica for her courage in protecting others. Later, the Principal is shocked to receive a letter from Claude, her former apprentice. | ||||||

Situated under the Witch Hat World Tree, the 1,000-year-old Diana Royal Magic Academy, founded by the witch Selene, hosts 600 students in Middle and High School. Principal Jeanne reinstates Claude, but remains furious he vanished for two years. To allow Claude to teach in human form, Spica must resentfully kiss his anus every morning, igniting scandalous rumours from the outraged Dorm Mother. Spica frees student Io Taurus from being stuck in a wall, who explains students form 12-student covens with one teacher for three years. Spica soon meets her eccentric classmates: playboy Astraea Libra (psychic magic), Castor Gemini (self-cloning), Leo Regulus (animal transformation), and Io (giant transformation). To her horror, they are all in Claude’s coven; Claude having been assigned the 12 most troublesome students to atone for rumoured cowardice, and warned if even one drops out he will lose his job permanently. Academically, Spica struggles while Ewe Aries aces every question while asleep. During practical assessments, Claude notes Aria's high skill, Hana Sasorijō’s collateral-heavy Scorpio Poison magic, and Tarf Cancer’s capabilities. Spica finishes dead last. Because the academy expels the worst performing 10% of students each year, Claude sentences her to remedial study classes. | ||||||
| 4 | "Castor Gemini's Fate" | Unknown | Unknown | TBA | May 1, 2026 | |
|
The students become infamous for their behaviour, earning their coven the nickname "Pandora's Box." Jeanne warns Claude that Castor faces expulsion for truancy. Claude and Spica intervene as Castor beats a student he claims groped him. Castor declares he would rather be expelled than learn from Claude, revealing he was among the students Claude abandoned during the cultist attack. During the confrontation, Castor falls into a river and touches Io's hand, revealing he shares a body with his twin sister, Pollux. They swap places whenever they touch the opposite gender, which is why Castor so often beats up boys, as he appears when they grope Pollux. While Castor is violent, Pollux is cheerful—yet both resent Claude. Claude later admits to Spica that while abandoning students was a necessary tactical choice, his subsequent two-year disappearance was unintended. Suddenly, monsters ambush them. Pollux runs out of magic, leaving her naked as her cloned clothes vanish. Claude arrives, defeats the monsters, and genuinely apologizes for his past actions before rushing away to secretly transform back into a cat. Touched, Pollux convinces Castor to give Claude another chance and attend class. Meanwhile, a shadowy group watches from afar, targeting Spica specifically for her "Rebirth" power. | ||||||
| 5 | "Spica and Aria" | Unknown | Unknown | TBA | May 8, 2026 | |
|
Claude fears Spica will fail midterms because her lack of imagination limits her magic. Resentfully, Spica asks Aria for training. Aria demonstrates how she shapes water freely, then challenges Spica to a Lophorn Rabbit hunting contest. Aria is secretly upset that Spica spends more time with Claude than her. A week later, Claude and Aria are amazed by Spica’s progress and her willingness to endure injuries from untested spells. Though Spica loses and must serve as Aria's maid for 24 hours, Aria is happy they are close again. Claude decides to select a Student Leader for the coven. While observing candidates over the weekend, Claude is stuck in his cat form. He is adopted by a delusional Merrow Pisces, who forces him into a dress, and is subsequently bothered by a crude Prince Chiron Sagittarius and his over-loyal servant Tarf. After Hana Sasorijō accidentally spills a sex potion on him that attracts the entire dorm, Capella Capricorn calmly dispels its effects. Impressed, Claude appoints Capella as Leader. Later, Claude reveals the midterm is a high-stakes dungeon exploration. While Hana confidently promises her family she will top the first-years, a giant Griffon suddenly approaches their airship enroute to the exam. | ||||||
| 6 | "Midterms" | Unknown | Unknown | TBA | May 15, 2026 | |
|
Claude reveals the gryphon's immense nest is the dungeon, and the midterm requires stealing gold before sunset. Teleporting to safety is an instant failure. Claude hopes the students discover the dungeon's true meaning, but grows incensed when the incompetent Spica delays herself and a furious Hana from entering for ten minutes. Spica assumes Hana dislikes her due to a crush on Claude, while Hana expects Spica to be useless. However, Spica surprises her by trapping a gryphon in a vine cage. When monster hornets cause the bug-phobic Hana to panic, she accidentally burns nearby students with acid rain. Their contempt drives her back to hostility aimed at Spica. Meanwhile, Ewe is disqualified after falling asleep and being eaten, while Chiron and Tarf are also eliminated. An angry Hana sets indiscriminate poison traps, claims victory, and abandons Spica. She then encounters an immense, two-headed mutant gryphon using lightning magic. A flashback reveals Hana accidentally poisoned a child, leaving her terrified of causing or receiving harm. The gryphon overpowers Hana, but Spica's vine shield rescues her. Spica grabs her hand without fear of poison, accusing Hana of secretly wanting friends. Realizing wood resists electricity, they combine their magic to injure the gryphon, which strangely smiles at Spica. | ||||||
| 7 | "Cross Magic" | Unknown | Unknown | TBA | May 22, 2026 | |
|
Spica and Hana combine their powers using Cross Magic. Embracing rather than fearing her Poison Magic, Hana’s cooperation with Spica sprouts hundreds of poisonous flowers, defeating the gryphon. Spica is glad they make a good team. Elsewhere, Castor fails to cooperate with Astraea and Io, forcing Pollux to take over their shared body. Hana finds the required gold, but Spica collapses from exhaustion. Claude is visibly disappointed. When Spica awakens, Hana reveals they ran out of time and failed the exam. Spica feels guilty, but Hana is satisfied, having found something more valuable than victory. Meanwhile, Aria passes with Merrow Pisces, alongside Io, Astraea, and Castor/Pollux. Despite their technical failure, Claude praises Spica for cooperating with Hana, leading Justice to suspect Claude is growing as a person and an instructor. As the only failures, Spica, Hana, Chiron, Tarf, and Ewe must attend a three-day remedial camp in the frozen mountains where academy founder Selene trained. Anxious about their blossoming friendship, Hana overthinks things when invited shopping with Io and Aria. Spica insists on visiting the Witch Hat World Tree, where everyone agrees Hana has become nicer. They commemorate their first shopping trip with a group photograph. | ||||||
