Her life changes when a mysterious man named Keiki pledges his absolute loyalty to her. After a violent monster attack at her school, she is thrust into the fantasy realm of Kou. Accompanied by two classmates and armed with a magical sword, she lives in this new world under the protection of her newfound subject.
