“Wait… the male lead’s name is Hirius, and the female lead’s name is Diana…? Oh my god… Of all the novels, did I really get stuck in that horrible one?!”
Diana, the protagonist, realizes she’s been reincarnated into a novel infamous for being a chaotic mix of female-oriented romance fantasy and male-targeted fantasy—truly the worst of the worst. As if disliking the male lead wasn’t enough, she remembers that in this disaster of a novel, her character, Diana, is destined to die from exhaustion in the role of a healer after ending up with Hirius.
“No way—I refuse to die like that!”
Determined, Diana decides to test if she possesses the same overwhelming magical powers as her character does in the story, and quickly awakens her ridiculously strong abilities. Things go well enough as she impresses everyone during a magical assessment, earning a spot at the Academy—the very center of power in the empire. But there are many obstacles in front of Diana, such as Hirius and his devoted follower Arahel. Plus, her plans only get more complicated as she becomes entangled with a suspicious man named Leo, who seems to be hiding within the Academy.
Will Diana be able to achieve both power and love?
