Once upon a time in the magical kingdom of Japan there lived a young girl named Mami. Always she would ask her parents to read a children’s book by the name of Guri & Gura in which two field mice share good times together. Her most favorite story of all was the one in which Guri and Gura find a large egg and make a big fluffy cake out of it. However, as the years passed by and Mami grew into a woman, she gradually stopped reading the adventures of Guri and Gura and eventually went to work as a reporter for RocketNews24.
One day, her wicked step-editor called out, “Maaaaamiiii! Write me something about food! I’m hungry!” Checking the internet for something to write about, Mami learned of a famous café in Osaka. Other women wrote marvelous things about it saying, “It’s a real picture book world!” and “Everything about it is cute!” Thinking this was a nice place, Mami boarded a train for the land of Umeda not knowing what was waiting in store for her.
