Konjiki no Moji Tsukai Novel

A summoning ritual brings five individuals to an alternate world facing a catastrophic threat—a demon lord whose power endangers the realm itself. Yet this summoning contains a critical error: only four heroes were meant to be called upon, leaving one person an unwilling participant caught in circumstances beyond their control. This accidental arrival transforms the situation into an unexpected predicament. With the fate of an entire world hanging in the balance and a demon lord awaiting challenge, the question becomes how this unintended bystander will respond to their sudden and unwanted placement into a battle they never sought. Their decision and actions will determine not only their own survival but potentially the outcome of the world's desperate struggle against its greatest menace.
