Sheila's transformation

Pushing the door open, Cristian froze at the sight before him. On the bed, Sheila was wrapped in a white blanket but the chains connected to her ankles and wrists almost made him erupt.

The temperature of the room spiked by several folds but he took a deep breath to calm himself.

The chains rattled as Sheila turned to him, her pure white eyes glaring at him but they flickered for a short while, causing her to swing her arms, hurting herself even more.

The chains had runes, which sealed her powers and from how they were created, Cristian figured out the others had no other choice.

"What are you doing in her body?" He asked calmly, clenched his fist, and the chains broke. His Will grew stronger and stronger and soon it would be able to do feats, not one less than engulfing an entire city in flames.

The moment the chains broke, Sheila paused for a second, then something wriggled underneath the blanket before she shot toward him.
