As Kuri woke, she shivered. She felt very cold, and weak.
Shuddering in the corner was a shadow, whimpering and sobbing.
Kuri searched her memory. She had seen Reiko, moving, and lunging for her, attacking.
Had her magic created some kind of abomination?
Kuri stood shakily. She felt sad. So very very sad. Guilty, shameful, sorrow.
As she stepped closer the feelings deepened, agonizing her heart.
"Reiko?" Kuri whispered. "It's me. Your sister."
She turned on the light.
Howling, Reiko receded into the corner.
Her eyes red as blood, her skin very pale.

Kuri stepped close and embraced her sister. "You drank my blood."
Another cringe.
