participant in the Royal Road Writathon challengeOne day a large number of people suddenly vanished from earth, all transported to a different world. A dark place as cold as frost itself, a frozen forest that never dethaws. Our protagonist has a hero complex, and wishes to save people due to a difficult past, but its a little too much for his own good. It allows his immaturity to show, despite his bravery. He meets a girl from his world, trained in sword fighting and gardening. A middle aged man, a chef and doting uncle. As well as a girl born from ice, someone not of his world, but of the one he came to. A mystery to him, her cold icy blue eyes stare without emotion and her unexpressive personality causes his struggle but also a sense of peace.Our protagonist Kajito has to find a way out of this nightmarish world, while saving the people he grows attached to. He needs to return home to see his dear little sister again.
