So this takes place somewhat near the end, when they first meet the twins in a banquet, and they just found out they were the ones that trapped her, after some drama, this happened:

"Kukki couldn't stop the tears falling down her cheeks. She kept backing up on the table and screaming no. the twins, confused, climbed onto the table to try and stop her. "It wasn't my fault!" Kukki whispered, falling on her knees. A soft golden glow started growing around her but died down just as quickly as it came. Niah reached out to comfort her but as soon as her finget tip touched her shoulder, her neck snapped up and her eyes went completely blank and the golden glow became stronger..."
