The college life of magical girls operating in secret, and Guest who interferes with them.
A confrontation between a four-member team of Jewel Magical Girls disguised as college students and Guest, the reclusive Villain King hiding at the same Z University.
Guest, who never steps onto the front lines, uses mist magic to induce cognitive dissonance and memory errors across the campus.
The magical girls must protect the central barrier core in the clock tower against monster attacks and friend-or-foe identification interference.
A secret campus information war between the guardians and the mastermind hiding their identity among ordinary college peers.
Despite its peaceful appearance, Z University is the center of a massive jewel barrier that maintains the stability of the world. The core of this barrier is hidden in the clock tower of the central plaza, and to protect it, four guardians—Choi Yujin, Kang Juhee, Eun Seowoo, and Park Mina—lead double lives, disguised as ordinary college students struggling with assignments and exams.
However, peace is shattered when a mysterious, thick mist begins to blanket the entire campus recently. This mist disrupts magical detection and induces cognitive dissonance, causing the magical girls to mistake allies for enemies or experience psychological confusion.
All of this is a scheme by Guest, the Villain King who has perfectly blended in among the students of Z University to command proxy battles from the rear. Avoiding direct physical conflict, Guest summons monsters from the abyss vent beneath the Engineering Building and spreads mist to waste the guardians' movements.
Amidst the fatigue of exam periods and the confusion of information errors, the magical girls must fight under the penalty that the barrier will weaken if their identities are discovered by civilians.
Against the secret psychological offensive of the hidden Villain King Guest, will Choi Yujin and the four guardians be able to correct the cognitive errors and safely protect the campus barrier? The curtain rises on a campus information war where academics and combat are intertwined.
