YMMV / The Caregiver

• Complete Monster: The Karasu Tengu is a demonic entity who cursed the elderly Koga Souichi and his family in order to merge his body with Souichi. Driving the spirit of Souichi's wife Haori insane, the Tengu made her murder the entire family, including their young children, as The Tengu held a ritual on Souichi. When Tomita Sachie discovered the Tengu and Haori, the Tengu spirit drove her insane and caused her to commit suicide. Chasing down Kuramoto Naomi in order to stop her from meddling, it's revealed that the Tengu already succeeded in possessing Souichi and presumably kills Naomi by the end.
