The protagonist is reincarnated into a world where magic is paramount, having wished for a peaceful, reclusive life. Upon birth, he is revealed to be Prince Reinhardt of the Ortheas Kingdom, son of King Jilku Ortheas and the renowned "Flash Princess" Gizerotte. However, a magical aptitude test reveals his maximum magic level to be a dismal 2, with no elemental attributes, rendering him capable only of barrier magic. This shocking result leads his father to declare him stillborn, a decision made to protect his own image and political standing, despite the protests of the loyal border count, Gardo Zenphis.
Reinhardt, now a helpless infant, is abandoned in a forest. He quickly discovers his cheat ability is the versatile barrier magic, which he can manipulate with incredible ease and precision. He creates invisible barriers to move, defend himself, and even to see through walls, effectively creating a rudimentary form of remote viewing. His abilities are so advanced they defy the world's understanding of magic, leading to confusion and fear among those who witness them.
Meanwhile, Gardo Zenphis, the only one who advocated for Reinhardt, secretly rescues him. He takes Reinhardt to his castle and raises him as his adopted son, Hart, hiding his royal lineage and low magic aptitude. Gardo's motivation stems from a deep sense of justice and a desire to protect Reinhardt from the machinations of the royal family. He is aware of the King's political maneuvering and the Queen's ambition.
Ten years pass. Hart, now a ten-year-old boy, has lived a comfortable, secluded life under Gardo's protection. He has honed his barrier magic, creating sophisticated constructs like an AI-powered clone of himself and a VR interface to control it. His younger adopted sister, Charlotte, possesses exceptional magical talent, surpassing even Queen Gizerotte, and harbors a childish delusion that Hart is a secret hero fighting an "evil organization."
The political landscape is tense. King Jilku's authority has waned, overshadowed by Queen Gizerotte's immense popularity and influence. Gizerotte, a cunning strategist, manipulates events to consolidate her power, viewing Reinhardt's existence as a potential threat, even though she believes him to be a "cripple" with magic level 2. She plans to eliminate Charlotte, who possesses superior magical talent, and frame Marianne, the King's daughter from a previous marriage, for the deed. Gardo, aware of these schemes, intends to protect Hart and Charlotte. The story concludes with Hart preparing to leave Gardo's castle to establish his own secluded research base, a plan complicated by Charlotte's insistence on joining him and the looming threat of Gizerotte's machinations.
