Villainess Level 99: I May Be the Hidden Boss But I'm Not the Demon Lord - S01

The start of Light Magic and the Hero, an otome RPG, plays out like usual: the heroine, Alicia Ehnleit, runs into her three love interests one after another, then inevitably crosses paths with the villainess. Yumiella Dolkness may come from nobility, but her dark hair and rare dark-type magic, both tied to the Demon Lord, strike fear into anyone who sees her. At five years old, Yumiella regains memories of her past life in modern Japan, and she also realizes her fate is to become the hidden boss who shows up after Alicia and her suitors beat the Demon Lord. Yumiella refuses to live the way the game says she should, and since she likes the fantasy parts more than the romance, she decides to build up her magic and grind levels in secret. But it all comes apart on the day of the Royal Academy's entrance ceremony. Yumiella's power is measured at level 99, something everyone thought impossible even for the royal knights, let alone a 15-year-old girl. With the royal family asking for her help and everyone else demanding she prove her strength, Yumiella realizes her dream of a quiet life is off the table.
