"I had always thought of my sister as a jerk. I thought she didn't care about me when she had escaped. I thought that she only wanted freedom for herself. But I was wrong. She isn't a jerk. In fact, she's one of the most kindest "demons" in existence! So don't you dare call her something that she isn't!"
- "Well bravo, you little shithead. You just made the worst mistake of your life. Angering me."
- — Kotori to Kyoko when they first met.
Kotori Byern (コトリ ビエルン Kotori Baierun) is the fraternal twin sister of Kyoko Byern. After hearing that her sister had escaped from Paradonix, Kotori made several attempts to escape as well, all of which failed. This led to her determination to become stronger, and she soon was put through the same process in which Kyoko was forced to go through to turn into a demon. During her time in captivity, she soon started to resent her sister for supposedly, "leaving her behind". However, after managing to escape from Paradonix, she found out that Kyoko had actually been trying to rescue her from Paradonix.
