"T-Thanks to you... Mom and Rou can live happily... and I... will always be grateful to you."

Brief Summary: Tomoe was born in the northern region that later became the Demon Lord's domain. After her father died of illness (shortly after her sister Rou's birth), she fled with her mother and sister as refugees. During a kingdom event organized by the King (you), she revealed her ability to speak with animals. She later confessed that she could also communicate with demons, making her an extremely valuable asset. She was adopted by your parents as your stepsister to protect her within the castle.
