Asahina Ema

Ema is the teenage daughter of the well-known adventurer Rintarou Hinata. She is in her second year in Hinode High School.
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 "Chii".

Spoiler

It is later revealed that she is adopted (her real parents had died). This revelation causes a problem for her at first because her so-called father had been keeping it from her for so many years. However, Louis helps her through this with his own experience, and Juli also reassures her of her father's love.
