Chiyo was five years old when her mother gave birth to Natsu. 

It’s easy to remember the small, squirming newborn with pink cheeks and large, dark eyes. It’s easy to recall the first time Chiyo held her sister, realized this tiny, warm thing was a person, a human being.

Their mother passed not a month later from complications. Their father was devastated. So, the task of raising Natsu naturally came to Chiyo. They’re more than sisters and best friends and, now all alone, Chiyo’s duty has not, will not, and cannot change.

Because now she has two people to protect.
