Keel/Relationships

Naofumi Iwatani
Keel showed hostility from the start, but she became attached to Naofumi seeing him as a big brother figure.

Raphtalia
Keel and Raphtalia have been friends since childhood. After Raphtalia liberated Keel, Keel becomes determined to protect her. She even willingly entered into a slave contract with Naofumi, in spite of the past traumatic experiences she suffered as a slave, in order to increase her strength.
