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. His 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 verified to be female she is made out to be more of 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 whining when wanting food from Naofumi. Despite how she acts, she helps bring together the slaves and acts as a sort of leader.

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

Trivia

 * Keel wasn't meant to be an important character, however, the personality the author gave him overlapped with another male character he planned to make down the road, so he decided to give ‘him’ a little… quirk. (Sex change)
