An Ordinary High School Girl Becomes a Demon Lord in Another World

Airi Katagiri is an unremarkable high school student whose life takes a drastic turn when a mysterious magic circle abruptly whisks her away to another world. She awakens in the Demon Realm, where a faction of demons had been conducting a ritual to resurrect their fallen ruler. However, instead of reviving their lost master, the ceremony unexpectedly summons Airi. To everyone’s astonishment, the ordinary Japanese girl has somehow inherited the immense power of the Demon King. Thrust into a position she never sought, Airi suddenly finds herself ruling over a domain of demons as their new sovereign. The transition from classroom life to commanding a dark realm is jarring, and the weight of her newfound authority brings immediate complications. Tensions between humans and demons are already dangerously high, making her sudden ascension a volatile catalyst for potential conflict. Now caught between two vastly different worlds, Airi must navigate the treacherous politics of the Demon Realm while grappling with her extraordinary circumstances. As she struggles to understand the true nature of the power she wields, she faces a daunting question: what does it really mean for an ordinary high school girl to become the new Demon King?
