I became the mother of 'Ainspanner,' who was presumed to be the final mastermind of this novel. I was supposed to be a bad stepmother who abused him when he was a child and eventually became the first to be killed by him when he became an adult. I was thinking of a plan to escape my tragic fate when I saw the young future villain and the naive, innocent look on his face. However…

"What an adorable child! He’s so cute I want to bite him! How could anyone abuse him?"

He was so cute that I couldn’t believe he would become a villain when he grew up. So, I decided. I will protect him. This way, he’ll save me too when he’s all grown up.

Grimoire Alchemist is a dating sim popular among both boys and girls in Japan. The player’s rival in love, Claudia Ellington, is jokingly called the “Villainess of a Thousand Deaths.” But this alias of hers is actually no joke; she really does die a thousand times in the game!

Determined to escape the dire fate she has in store for her, Diehard Grimoire Alchemist Fan #1 (now the reincarnated Claudia) does everything she can to avoid entering the love interests’ romance routes in an attempt to separate herself from the game’s storyline and save her own skin.

Join her as she (much to her dismay) magnificently steals the hearts of the game's charming love interests!
