Keel

A demi-human of the War Nui species and Raphtalia’s childhood friend, Keel identifies as male but is biologically female. Due to the effects of the Waves, Keel became a slave and suffered abuse until being rescued by Naofumi Iwatani. After his rescue, Keel became one of Naofumi's companions and joined in battle. He was injured during the Spirit Tortoise incident but returned to health through treatment. After recovering, he worked to help restore the village, raised his skills, and became active as a traveling merchant. Once it was revealed that Keel is female, he began crossdressing as a woman for his merchant activities, becoming the village’s top seller.

In combat, Keel wields a one-handed sword and learned to transform into a beast form under the instruction of Sadina. His transformed appearance resembles an anthropomorphic Siberian Husky, which is considered cute by those around him. He can also use magic and enhance his physical abilities by howling. As Naofumi's slave, Keel regained his cheerful personality, but he still suffers from past trauma. In his attempt to overcome it, Keel asked his ancestor Horn to perform modification surgery, but since he could only attain a cute form, he gave up. However, by making use of his beast transformation, Keel is able to change forms to match his attributes.

In the sixth loop of "The Reprise of the Spear Hero," Keel reappears as a slave and wears cute outfits while working as a merchant. In Zeltbull, he learns beast transformation from Elrasla Ragnarok and acquires dual-wielding skills.
