Keel

Keel (キール) is a resident of Raphtalia's home village and her childhood friend. She became Naofumi's slave in hopes of rebuilding the village.

Appearance
She is shown to be a young boy around the age of 10 with dog-like features, later revealed to be a girl. Her tomboyish appearance fooled everyone, including Naofumi, who accepted her as his slave under the impression that she was male. When Tact asked his harem not to hurt women, every other woman in the Holy Hero side remained unharmed, with the exception of Keel.

Human
She is initially described as a young man around the age of 10 with dog-like features. However, as she levels and her appearance ages as well as her being, she is verified to be female, making her out to be a tomboy who could easily pass as a pretty boy.

Dog Form
Her dog form takes the appearance of a loincloth-clad puppy (specifically, a Siberian Husky) who walks on two legs.

Personality
Keel can be bratty and whiny when wanting food from Naofumi. Despite how she acts, she helps bring together the slaves as a leader of sorts.

Background
Throughout her life, Keel was raised as a boy. Her father treated Keel like his son, telling her that gender was a state of mind.

Trivia

 * Keel originally wasn't intended to be an important character, however, the personality that given to him overlapped with another male character that the author planned to make down the road, so Keel's sex was altered.
 * Keel's favorite food is crepes.
