An avid MMORPG player suddenly finds herself trapped in the world of an otome game she’s barely touched—and only out of obligation. Now inhabiting the body of Bianca, the plain and overlooked friend of the villainess, she’s exhilarated by the chance to live in a world brimming with magic. Determined to make the most of her knowledge of the game’s opening events, she ventures into a beginner’s dungeon to gain strength. But when a seed of darkness disguised as an innocent puppy crosses her path, her plans spiral out of control. It pushes her to level up, seize an overwhelming power, and face the temptation of becoming the next dark overlord. What to expect: No harem. Posting schedule: 3 days a week. Dungeons, academy, empire building. A contract with the darkness. An isekai story where the MC has the potential to become the most powerful hero ever (or the villain, or the demon king...). A slow development of the MC's potential. An OP, devastating ability that the MC can only use once per day—and it's better if she avoids using it. A world where leveling up is difficult and the dungeons are controlled by the army. A system of magical affinities based on personality. Starting from chapter 19, chapters will be at least 1500 words, with an average of 2000.
