A woman gets hit by a truck and gets sent to the world of an otome game that she had played earlier that same day.

It’s about a guy who was fired from being a court wizard, so he became a rural magical teacher instead.

Awakening her dormant abilities as a devil one day, Yuuko Yoshida aka Shadow Mistress Yuuko, is entrusted with the mission to defeat the Light clan's shrine maiden, a magical girl, by her ancestor Lilith. Yuuko meets magical girl Momo Chiyoda through her classmate Anri Sada, and challenges her to a duel, but loses quickly due to her lack of strength.

Since then, Yuuko has struggled with her role as a devil and her duel with Momo, and borrowed help from her regularly. However, by a strange coincidence, Yuuko also weakens Momo by taking away her power to cooperate in protecting the peace of Tama city.

“The Hero defeated the Demon King in the war of men against demons…” Those kinds of stories are a thing of the past. Nowadays, adventurers, demons, Heroes, Demon Kings, and so on are all occupations that no longer involve putting one’s life on the line. Peace has returned to the world, and dungeon exploration has now become a form of entertainment. Adventurers and monsters now all fight using clones they’ve created with magic in an extremely popular form of dungeon clearing where nobody dies. The footage of the dungeon getting cleared gets broadcasted all across the continent, and I’m a member of a Hero’s party that was ranked the 4th most popular in the world… but not anymore. Parties had a limitation of 5 members, and I was told that an unpopular job like Black Sorcerer would only get in the way of getting to 3rd place or beyond.

Now that I became unemployed, I was forced to find another party but I just couldn’t find one. One day, I encountered a beautiful blonde red-eyed woman who told me she had a job for me. After being so touched from having someone recognize my abilities far more than my past comrades, I ended up agreeing to take an interview without asking for the details. When I arrived at my destination, I was at the world’s hardest dungeon where no party has ever reached the final area, the Demon King Castle, where the Big Four and the Demon King were waiting for me. This is the story of a Black Sorcerer that was kicked out of a Hero’s party and joined the side of the Demon King Army to repel the Heroes. (Source: Novelupdates)
