Sachiko Tomoda was just a very ordinary high school girl. Her classmates were also very ordinary. Pink hair, orange hair, silver hair, dead fish eyes, high school students who solved cases, and so on. They were all ordinary people. One day, she obtained a special ability. And so, Sachiko's amazing journey began. Even though Sachiko looked as quiet as a chicken on the outside, her inner thoughts were unusually rich. Here's what happened: Sachiko, Eraser, and other accomplices were eating together at a table. Sachiko thought to herself, Ahhhhh, will I be poisoned to death!! Ahhhhh, this chef's cooking is too delicious!! Ahhhhh, will I become the legendary demon!!! Sachiko and one of the captains sat on the floor, quietly drinking tea. Sachiko thought to herself, Damn, will I become a dead person after drinking this cup of tea?! Ahhh, I don't want to!! Damn, is this hell? It's so scary!! Someone save me!!! Can I still be human?!! Later, Sachiko boarded Bearded Dad's ship. Bearded Dad said, "Be good and call me daddy." Sachiko said, "… Sorry, I already have a daddy."
