Shirley Fennes
Shirley Fennes Shirley is Senel's sister, two years younger than he. She is constantly trying to protect her brother from the dangers that his job puts him in. She has a unique body chemistry, however, that causes her to fall ill should she come into contact with salty sea wind or water.

Normally she is calm and quiet, giving those around her an impression that she is frail. At the same time, though, she can be quite stubborn, and once she has decided upon a course of action, it is almost impossible to change her mind about it.
