After dying in an accident a college girl finds herself reincarnated into a fantasy world; one identical to a game she has played. She is the raven haired Yumiella Dolkness and is proficient in dark magic... two things that are hated and feared in this world. She is shunned by her family and passes her time raising her magic level. On entering school students magic levels are checked; ten is considered very impressive; hers is ninety nine, the maximum! At first she is accused of cheating in the test but when it becomes apparent she really is that level her fellow students fear her. She sets about trying to fit in and helps other students raise their level, in particular Alicia Ehnleit. She is a practitioner of light magic and was the protagonist in the game. As is usually the case they will ultimately have to face the Demon Lord.
Isekai series are two a penny these days and while this one doesn't exactly bring anything new to the genre it is rather fun if you enjoy the genre. It starts well and early episodes are amusing as Yumiella easily overpowers those who think she is a fraud. While there isn't a real sense of danger there are some decent action scenes as she helps others level up and ultimately face the Demon Lord. The characters are good, especially our protagonist. I liked the character designs and thought the animation was solid. Overall I'd say this is worth watching if you are a fan of the genre.
