In a fantasy world, they say anything is possible. Is it possible to turn your resentment into repentance, even if you are a demon? That's Tsubaki's question, as she keeps within herself what no human would want to. She couldn't ever deserve another person's forgiveness, but just so she could forgive herself, she quietly roams the world, killing monsters and protecting innocents. And yet, even then, unwilling to acknowledge it, she is itching for forgiveness, or at least, a partner. The gentle touch of another human.
