I don't own Black Butler :)) You are a half-angel, half-demon... For demons, their hearts don't beat until they pass their soulmate, they don't feel pleasure, they don't feel that many emotions. What happens when Sebastian comes across his soulmate...you. Will you accept or not? This is not modern^^

[Y/N] Rengoku, little sister to Kyojuro Rengoku, is on her way to becoming a hashira - just like her beloved slightly older brother. One difference between the two though: [Y/N] doesn't use flame breathing like Kyojuro does. She uses a technique known as bird breathing. Will she witness her dream of becoming a hashira coming true, or will she give up halfway? Or, even bigger question, will she survive?
