Korrin is the third protagonist of this series. She is one of the best demon slayers in her village, and being the second female in the village history to do so, faces ridicule. She has expectations constantly pushed onto her that others don't. she is determined to exceed those expectations, and probably curse out whoever placed them once she achieves.

Her younger brother, Axel, is the only one around who truthfully supports her, covering for her at every turn and being there to help when she needs it. Although, not without a little teasing.
