Potion, Wagami wo Tasukeru

The story centers on Kaede, a normal high school girl who suddenly finds herself reincarnated into a fantasy world full of beastkin, elves, and dragons. She spends an entire day walking to try and find her way in this new world, and rummages through her bag, where she finds a mysterious book. As it turns out, the book allows her to craft potions simply by gathering the necessary materials and chanting "Create." Kaede then plans to use this power to make her way through her new world, and get back to Japan somehow.
