Na Honja Guide

Ji-An, an S-rank guide in Korea who isn't compatible with any espers, people gifted with superpowers, finds herself on a strange continent one day. There, she meets Duke Wisrode, an esper she can finally guide. However, her excitement is short-lived when she discovers that she is the only guide in this land, which is full of espers, and the duke wishes to keep her to himself. Will Ji-An be able to find her way back to her own dimension safely? Or will she be stuck here as the lone guide forever?
