Kaoru was a normal office worker who loved to play otome games. One day, she was summoned to another world as a hero, along with four other people. They were supposed to defeat the demon lord and save the world, but Kaoru soon realized that she was just a bait. The king and the church planned to sacrifice her to the demon lord, while the other heroes would escape. Kaoru was outraged by this betrayal, but she had a secret weapon: her ability to create potions. She used her potions to escape from the castle, and decided to live on her own in this strange world. Along the way, she met many people who needed her help, and she used her potions to solve their problems. She also encountered some enemies who wanted to take advantage of her power, but she used her potions to fight back. Kaoru was determined to survive using potions, and maybe find some happiness in this world.
