Canon
One day, Bronya, looking for food, breaks into Sin Mal's home and threatens her. However, Bronya's pursuers follow her and attack her. Sin Mal then kills the pursuers and Bronya is able to leave.

"That day, an angel appeared in front of me. She showed me the light. She gave me the hope of living in this corrupt world. She planted seeds in my heart and soon left. I'm tracing her footsteps, chasing her shadow."

A few years later Sin's adoptive parents meet Cocolia, who wishes to adopt Sin from them. Sin Mal meets with Bronya and Seele once more in the courtyard, but Bronya and Seele are visibly afraid of Sin and Bronya calls her a monster. Because of her failure to become friends with them, (likely reducing her chances of being adopted by Cocolia since she does not get along with Cocolia's other children) her adoptive parents beat her. Sin Mal, lying on the shards of a broken mirror that was shattered during her beating, begins to hear voices. The voices tell her that the only way for her to become a human is to become the incarnation of sin, a trait that distinguishes humans from other beings. Her adoptive parents then try to sell her to a noble as a child bride in a bid to get rid of her, but Sin retaliates and splits the nobles head in half, stating that she doesn't want to be a monster, but rather a human. She then burns down the palace, meeting once more with Bronya, asking her if she is human now.

Some time passes and Sin Mal undergoes the X10 experiment where Bronya and Seele learn more about her childhood, but unfortunately the experiment fails.

During the second time Bronya reveals to Sin that she called her a monster because she was afraid of herself.

"Sin... I'm sorry. You're not a monster. The one in the wrong here is me... Who was afraid of becoming a monster. When I first met you on that rainy night, I saw the evil reflected in your eyes. .....It felt like my heart shattered. Before I met you, I fought and killed to live, and dyed my hands red with blood...... I was scared... The reflection I saw in your eyes was of a monster wearing human skin. So I avoided you... I was scared. But I wasn't scared of you, I was scared of what I looked like to you. Sin, I'm sorry."

Afterwards Sin and Bronya are able to become closer.
