Ema Hinata is the daughter of a well-known adventurer, Rintaro Hinata. After her father remarries, she moves in with her new 13 stepbrothers. She is very good at cooking. Her father's job had always left Ema feeling alone, but now with her new family she feels happy and safe. She has a talking pet squirrel named Juli who is always saying that her new family is a pack of wolves and that she must always be well aware of her surroundings. Juli can only communicate with Ema and (as it is later discovered) Louis, and both Juli and Louis call Ema "Chi."
