I Am the Future of the Demon Cult

Mo Ying is a high school student, currently on summer vacation after her second year. She’ll be starting her third year when school begins again. As a student about to start her final year, she doesn’t really get a summer vacation. Every day, she’s buried in an endless sea of practice problems. One day, she finds a key that can open a gate through time and space, letting her enter the legendary Demon Realm. They tell her she is the hope of the demon race, its future heir. She was sent away to study back then, and now she’s returned. Surely she has learned supreme techniques and will lead the demon race to revival! Mo Ying: ... She must have fried her brain doing practice problems. But... Mo Ying looks at the exam paper in her hand, then at the demons waiting for her to reveal her techniques, and smiles. Great. Now they can experience the agony of being tortured by language arts, math, English, physics, and chemistry too. Heh heh heh... Theme: Without rules, there can be no order
