Kazuto Kirigaya, an ordinary high school student with a love for books and a knack for getting lost in stories, stumbles upon a dusty, ancient tome hidden deep within his school library. The mysterious book, glowing faintly with an otherworldly light, piques his curiosity. Without thinking, he opens it—and in an instant, reality twists around him.
Kazuto awakens in the grand throne room of the Kingdom of Aishihara, face-to-face with King Yukishiro, a gentle yet eccentric king, and his fierce, beautiful daughter, Princess Reina. To Kazuto’s shock, the king declares that Kazuto is the long-awaited Accidental Summoner, a prophesied hero destined to restore balance to the realm. His one and only weapon? A cursed artifact called the Charm of Miscommunication, which guarantees absurd romantic misunderstandings with anyone he grows close to—especially the princess.
