46 parts Ongoing In a shocking twist of fate, an ordinary school is transported from the familiar world into a vibrant, fantastical kingdom brimming with magic and mythical creatures. Unbeknownst to the students and staff, this realm is plagued by an age-old menace: a powerful demon king bent on conquering the land and casting it into eternal darkness. Stripped of their routines and comforts, the bewildered group soon learns of their urgent mission: to aid the kingdom as its last line of defense. With courage and resilience, they must rise to the challenge, leaving behind the ordinary lives they once knew.
In this world, a mystical system has awakened within each of them, bestowing the ability to unlock and harness hidden powers that reflect their unique potential. This system offers new paths to greatness, empowering them to forge alliances, master unfamiliar skills, and confront their deepest fears as they prepare to face the demon king's unrelenting forces. However, not all the students are blessed with equal opportunities or strength.
One student, an unlikely hero among them, discovers he has been assigned a lower-tier class-a position with few benefits and even fewer options. Unlike his peers who wield swords, magic, or other mighty abilities, he finds himself restricted to a limited set of skills and weaponry, with only a shield at his disposal. Despite feeling the weight of these limitations, he becomes a symbol of determination and tenacity, relying on strategy, resourcefulness, and an unyielding will to prove that strength isn't always defined by power alone.
